OK version two. The Fishman Powerchip has issues switching it simply doesn't always work. There are two solutions one use some device between your guitar and amp to fool the switch into switching or run the piezo preamp in mono mode piezo only. This is the wiring for that. This will work for any 2nd generation or converted Fly.

It is just an old NOS tone cap similar to the ones used on old LPs. I can't remember the value but it cuts only the highs and not the mids. I like the sound better and would put one in all my Flys if it didn't goof up the ribbon.

Yup pretty amazing Alex. Ever think of taking Flys on a repair and mod basis? This forum could use someone like you and frankly i'm suprised that we don't have someone doing it already.

Does it all checkout Paul. You know drawing this stuff is like writing you always find mistakes after posting. I played the guitar all evening and it might actually sound a bit beefier fuller then it did with the mags running through the board. I hate to say something like that because of  course I can't do strict blind a/b test to verify but it is possible that all those surface mount bits and the mixing circuitry was thinning the signal some how?

Simon I certainly would entertain the possibility of doing some work to help someone out. But I do think they should make use of local techs first and shipping is such a risk.

You guys remember this drawing the mags bypass the board the other drawing the mags go through the board just like a "refined" Fly.

Alex, nice work! I admire it, and wonder about what you said about the mag tone... It makes sense that something would get lost going through the board. Thanks for posting this...

Alex, You really don't know what the value of that cap is?  Can you measure it? I've got a great selection of NOS caps to try.

Your diagram looks correct to me.

I am very curious about the bypassed sound myself. I'd like to do that with one of my flys.

Simon, I'll step up right now and offer anyone my services to repair or mod any fly electronics. Just let me know. Check my website for reference.

If this Ghost system works with the piezo I gave Javier it would be nice to know someone on the Forum that can do the work. I mean just about any good tech could do a refined Fly but the older ones could be a bit trickier for them. Either of you feel comfortable with doing that?

Alex, did that guitar have four pots in it before the conversion?  Looking at the photo, what control do you have in the original master volume position? It looks like only two wires are attached.
Title: PTP Conversion 1st gen With passive Mags
Post by: 908ssp on May 19, 2007, 11:06:31 AM
It is a 1st generation guitar so it had the typical master volume there. I honestly don't use the master or the magnetic volume separately and wanted a momentary kill switch. I'll do another thread on it.[;)]

If the Ghost system works, I'd have no problem doing it, Simon. Parts & shipping both ways of course would be the responsibility of the guitar owner.

Alex,

So I'm in the middle of my mods. I've got the mags wired passive, kill switch all working fine. Still no piezo. I've wired in the Powerchip and the output jack that came with. I feel like I'm missing something about the connections at the jack. How is yours wired. I've tried several things, still no piezo. Help!

BTW, the Ceramic set is currently in... sounds great. I haven't played through them much (been busy trying to get Piezo working), but I like what I'm hearing so far! It's what I'm not hearing that has me pulling my hair out...And I got precious little of that to spare![:0]

I can't be of much help with that I am afraid. Check each wire I know this wiring works I have done it twice now. But I know what I drew if anything isn't clear I'll try to help. Some of the colored wires are correct and some are arbitrary which I guess wasn't the best way of drawing this.

Do you have a wiring chart for the jack? You can down load one from Fishman.

Yeah, I've tried it the way it's drawn above. Not sure why it's not working... I've got the wiring diagram for the jack, so must be something else. I'll try again, see if I can find the issue.

So, I've checked some things out. I've found that I've got continuity between the "hot" plate and the ground pad on the bridge itself. In other words, the ground pad and the pad where the piezo leads attach on the bottom of the bridge are connected, somehow, though they don't appear to be (no obvious connection exists). I'm fairly sure this should not be the case, and can't see why this is happening.

Yea that shouldn't be. I just checked mine I have 500+ohms between the ground and the hot lead when soldered to the board. Which is too much to sound the continuity checker. Is the piezo lead still soldered to the preamp? The way they solder the shield and the core is pretty touchy and where I would look first. You might just cut a 1/2" off the lead and check the resistance if you now have an open circuit you can solder the lead back to the board. If cutting the end off does solve the short then removing the piezo leads one by one might be in order, yuck.[V]

Post by: Lwinn171 on January 18, 2008, 01:28:16 PM
Problem solved. You see in the pic above, one of the piezo's has a red lead? Guess what? That one was causing all the problems. I replaced that one with one of the old ones (I had replaced them all with new style, because one had broken). I didn't think anything of it when one of the six new ones had a different color lead. I replaced it with one of the old style and it works. Now the problem is the old style saddles are taller than the new ones, considerably so. I'll call Parker service and get another so they match up.

This also means that the original problem probably wasn't the ribbon wire, but this bad piezo element. So I may not have needed the PTP conversion. But now that it's done, I'm happy. Plus I've got the kill switch to play with, the master vol is out of the way (Always had to dance around that), and I've got some cool PU's.

Alex, I'll try the other set soon and decide. I really like the ceramics, though. The others would have to be pretty awesome to beat them.[8D]

I thought I was losing my mind. Whew!!!

By the way, the kill switch is a lot of fun. Thanks for your help, Alex.[^]

PS Alex, I think the mag vol in the original diagram is backwards. Check and see if I'm not just being dyslexic.

You're right the wiring is back wards. In the guitar the pot is at the top with the connection hanging down and then the terminals are on the left is correct but I turned the pot around so it is wrong. I'll fix the drawing and correct the link. Glad to be of help weird about that one saddle, that's a real head scratcher that is.

The above drawing is the corrected version.

Something finally clicked in my mind, and I started questioning some assumptions concerning the piezo. I decided to check the continuity between the piezo "plate" where the 6 leads attach and the ground pad right next to it (bottom of the bridge, pictured above). Should be none, was fully connected. Visually didn't make sense. The red one just stuck out to me, so I detached it, checked, and violla... no continuity. Customer service has one on the way to replace it. I was a hair's breadth from sending back the Powerchip, for testing. I'm so glad it didn't come to that!

Anyway, many thanks for your help, Alex. The mods are very cool, and I'd never had done it without your help. As very few tech's are familiar with Fly's, it's very reassuring to be able to do this stuff. I'm learning as I go, and a bit surprised I got through the rewire. But not for the weird bad "brand-spankin'" new piezo, I'd have licked it pretty quickly.[:D]

This is why I love this place

Thank you

Hi Alex!
A few things:
1.  would you please explain why this won't work in mono?  I have noted that Ryan's Blend (Balance) pot mod will work in mono.
2.  the piezo output on my chip is opposite that on your wiring diagram.  I had to ground the red wire (upper wire in your diagram) and use the white wire (grounded in your diagram) for the piezo output to the jack.  The red wire carried no piezo signal.
3.  I did end up reversing the polarity of the piezo to get the same "summed" output as before the mod.  Note that I am using a single amp for both outputs and this is probably a non-issue if using separate amps.

Thanks for making the drawing; I find it extremely helpful.
Peace,
SML

In the both positions of the mag/piezo switch the signal remains divided right to the jack if you introduced a blend or second switch at that point you might be able to feed both signals together into the tip of the chord. You could also run a stereo chord into a blend box and mono chord from there to the amp. This is all hypothetical because I haven't tried it.

The reason I went this way in the first place was because the Powerchip failed to switch to stereo/mono when I ran two amps and Fishman told me they had no solution except to permanently bypass the auto sensing switch in the Powerchip.

OK, I got that.  So the mixer is blending the signals so both go to the tip when it senses a mono cord is being used.  So what I/we need is a schematic of the mixer itself.  Then I could see how the mixer is processing the signals and perhaps find a way to mimic that passively.  

Anyone got a schemo of the mixer circuit?

I have tried the A/B switch and it does sum the signals and allow a mono output, with the mag pups bypassing the mixer circuit.  In fact, with my Mojo, the signal levels are more balanced than when both were going through the mixer.

Ah, but wait!  Couldn't the switch in the Fly be made to do the same thing the A/B box does?  Why not make the switch post-mixer instead of pre-mixer?

Good question I don't have an answer. In the old guitars they had a button that told the guitar whether you were running a stereo or mono chord. With the switch you could switch to the mono setting with a stereo cord and and play the piezos through the Mag amp. With the auto sensing switch you couldn't do that. Another reason the old guitars were better for some people.

Title: PTP Conversion 1st gen With passive Mags
Post by: Steven Murali Levine on December 05, 2009, 03:18:40 PM
thanks Alex.  yes, the part about the switch makes sense.  In mono everything goes to the tip no matter what cable is being used.  Well, the whole point for me is not to have to rely on the battery.  Might be moot if my new batt continues to work for more than 2 or 3 weeks.  I usually play several hours a day, so at the stated batt life of 200 hrs, I should be getting 60 to 70 days.

I am going to take a closer look at the switch/mixer interface, just for fun.  I have enough things on the ground to push and prod and would like to have as much as possible controlled on the guitar.

I recently posted this in the section for P-Series guitars but then I came across this post, so I was hoping someone might be able to help me with my problem i'm having with my 2009 P44V:

I have a Parker P44V which has developed a strange problem that I currently have been unable to resolve. I was hoping for some input from anyone who may have experienced something similiar or have suggestions as to what may be causing it.

During practice with the group I play with, after having been playing for about an hour, I stared to hear some static coming through the PA. At first, the static was very infrequent, but got more frequent the more I played, until it piezo signal coming from the Fishman bridge eventually dropped out completely.

I replaced the battery, and everything was fine for a while, but after further playing it started again.

I noticed that by pulling the guitar plug out of the input jack approximately 1/8" to 1/4", I was able to get the signal from both sets of P/U's. I talked to Parker about the possibility of the input jack being bad and decided to purchase one to swap out the original.

I have just installed the new one, and am having the same exact symptoms. If I take the battery out and then put it back in, things are fine for a while and then I start losing the piezo signal as before and eventually lose it all together. I think the volume control for the Fishman has a blend circuit board on it. Could the problem be coming from it? Could it be grouding-related?

I am afraid that I may have to send it to Parker for diagnosis and repair. Any thoughts or comments as to where this may be originating would be greatly appreciated.

Paul Marossy responded to my original post that the active electronics may be going bad and said if my guitar was configured like the refined Fly I may able to replace the Power Chip for around $90.00.

Any other thoughts on this would be appreciated.  What is the correlation between pulling the guitar cord out of the input jack slightly and getting both signals back?

Hey chatwithmrhyde, this is thread is for replacing the original electronics in the PRE-refined Fly to a point-to-point wiring scheme. Your P44V is a completely different animal, and no point-to-point conversion is needed on your guitar.

It could be that your jack has a loose connection, maybe one of the tabs inside is not making contact very well. On the Fishman PowerChip, it has an IC chip on it which is a solid state "smart switch" that can sense if you have a stereo or mono cord plugged into the jack. Maybe because there is a loose connection, it's fooling that chip into thinking a stereo cord is plugged into it. If that were the case, it would send the piezos straight to ground (if you were using a single amp & mono cord), which is the same as turning a volume control all the way down. Pulling the cord out would reset the "switch" and then both outputs would work for a little while until your jack connection went intermittent.

If that IC chip were faulty, it wouldn't switch properly and you could get that kind of behaviour as well. The only way to fix that is to replace the PowerChip.

So it's either the jack or the PowerChip causing your problem.

What is your normal setup? Are you running one or two amps? Have you tried different cords to see if your guitar always does this no matter what?

Try different amps. My smart switch would work with one amp but not another. I discussed this with Fishman and they admitted it was a known issue. Some amps impedance did not trigger the smart switch. That is the reason I worked out the full time stereo wiring for the Fishman Powerchip and Fly guitar.

Thanks for pointing that out! I remember that you have mentioned this in the past, but I forgot about it. [:I]

Hey guys,it appears that I have found the problem with the acoustic signal dropping out on my P44-V.  I found the "min" stereo/mono slide switch on the back of the guitar appeared to not be completely in the correct position (not all the way in the Mono position).

After sliding the switch back and forth and then moving it all the way to the mono position, after playing the guitar for over 2 hours, the acoustic signal has not dropped out.  Prior to this, I was never able to keep the signal for more than 45 minutes before it would drop out.

Any thooughts?  Thanks for the earlier posts.

908ssp or other regulars,

I will be sending this wiring schematics to my tech to switch my 98 Fly to PTP.

If the piezo is running in mono only, can the mag/piezo blend still work?

Thank you for any help.

Alex

Hi, I know this is an old post, but the photos are not available anymore in the threads i found about the battery less mod or bypassing the preamp for passive mag pickups... Im doing the mod for a nitefly m with fishman power chip... Someone could e mail me the info to do it?

Tus!! (my email carlospf22@hotmail.com :) )
