The swithcraft switch is nice, but it doesn't work. My fault, it is the wrong switch :(

I got my other Parker back from my cousin, took it apart, and could see what the switch is really doing. The old switch came apart so I guess the parts I couldn't hold together weren't working as they should.

Since I can see the connections make and break when the switch is intact, this is how it works. When the toggle is in the center position, there is no connection. In the up or down position it closes one of circuits.

I assume that when a circuit is closed, the preamp opens that circuit via a gated diode or something. (It's been a long time since I took electronics).

So is this on/off/on configuration?

So I sent the schematic to Stew-Mac and we'll see what they come up with.



I'll keep you informed.

It's like I'm going to guitar school :D

New switch to try, this should work. I'll report when it arrives and is installed.

AAAAAAARRRRRRGGGGGGGHHHHHH

It's a MIDI switch, and I cannot find a proper on/off/on spdt guitar switch anywhere. This is frustrating.

Any ideas?

Thanks
Bob

The “midi” switch should still work. If you mean mini instead that may be a problem relative to the hole size.

I’ll admit to feeling a bit like I’m wasting my time on this thread- the first reply from vj had all the info you needed. After you waffled I also chimed in a few times and even pointed to a place where you could choose from 100 on off on switches for less $$ than any of the other places. You could even find both varieties of switches there, order some of each and pick the one that best meets your need. 

There is some conflicting info which isn’t wrong for their guitar but turned out it wasn’t right for yours.

You seemed to ignore some very basic troubleshooting advice to help figure that out first and then you go to stew mac and get a switch that didn’t work.

I would love to help you but maybe go back and reread the thread considering what you have learned since?

Yes, I meant MINI not MIDI - I do so much MIDI work it just popped out of my fingers.

Sorry about wasting your time, I appreciate the help, but was simply very confused when you offered the first solution.

When I held the switch back together (it had come apart in pieces), it looked like on/on/on, and it wasn't until I got my other DF back that I realized you were correct on/off/on.

Yes I know how to use a VOM but the switch broke apart into pieces. It shouldn't have. The case was standing on the floor vertically (handle up, feet down) and tipped over. It didn't fall from a height or anything like that, it just tipped over on a wood deck because the wind blew it over. The toggle pushed itself into the switch and the switch came apart. The flanges where contact is made were also bent.

My other DF was loaned to my cousin, I had his strat for gig backup, and he wanted to try the DF. BTW he loves it and is looking for a used one.

It wasn't until my other DF came back that I could see what the switch is supposed to do.

I can't find hole dimensions in Mouser, so if the switch I ordered from Amazon doesn't fit, I'll call them (I've saved the page).

Yes this is a learning experience.

I can take a saxophone apart and reassemble (hundreds of parts), make MIDI backing tracks, create aftermarket styles for BiaB and sell them to musicians in over 100 countries, and so on, but guitar is my 7th instrument, and this is the first time one broke on me. Thus the confusion.

Funny, I can get anything to fix a sax at a sax site, but could not find this switch on a guitar site (GC, Sweetwater, Musician's Friend, Guitar Fetish, Music 123, SamAsh and so on).

Thanks to all that helped, I'll post results when I get it working again.

My earlier reply was probably harsher than it needed to be- sorry!  I really would love to see you get your guitar back to 100% or better, especially since you use it as part of your livelihood.

FWIW I had a number of similar situations last week where I gave someone info they needed but it seemed like "TL;DR."  lol. 

I get that, but there's a difference between saying "I don't understand, or what do you mean, or I tried that but it didn't work" vs. "any ideas?"

No doubt you're busy and it can be stressful when things you depend on don't work the way they should.

Keep us posted.  the mini switch will work electrically, but you're right that it probably won't fit the existing hole. 

You could drill a smaller hole to fit, and put something else in the existing one, but I'd be inclined to measure the existing hole and look for one that requires little or no modification.

First if all, thank you for all for your help. It was a guitar maintenance 1.01 lesson.

Problem is solved  ;D

I used a switch I got at amazon: https://www.amazon.com/Gardner-Bender-GSW-13-Electrical-Terminal/dp/B000BVXWF8/ref=sr_1_fkmr0_1?keywords=Gardner+Bender+GSW-13+Heavy+Duty+Electrical+Toggle+Switch%2C+SPDT%2C+ON-OFF-ON%2C+20+A%2F125V+AC%2C+Screw+Terminal%3A+Gateway&qid=1561761905&s=gateway&sr=8-1-fkmr0

The shaft size was a little bigger (15/32") but it fit in the same hole as the old switch (7/16" shaft size) with no problem.

It's a little stiffer than the original and makes a little louder acoustic click (but not loud enough to be a distraction). It reminds me of the switches that used to be on old Fender brown tweed amps that had a polarity reversal on/off switch.

It has screw terminals, and I put it together with the screw terminals, because if it didn't work, I didn't want to un-solder and re-solder again. I've got a couple of holiday week gigs so I'll probably go back and solder the connections, as I think that makes for a more reliable connection.

Here's a picture of the switch in the cavity:



And of course the outside looks fine, except that it isn't black, but that doesn't bother me in the least. It matches the whammy bar and the frets that way  ;)



If anyone has a similar problem, this is one possible solution. Any SPDT switch will probably do.

BTW, Stew-Mac will take the MINI switch back, and is sending a shipping label, since they were in on the e-mail techs and we both missed that the switch was a MINI.

So the story has a happy ending for me and my guitar!

Sweet!  So glad you got it sorted. 

And that picture is really valuable since it shows not only the replacement switch, but all the other guts and a good portion of the wiring too.

I had a thought since then that the guitar that has the on on on switching may be wired so the mags are passive, and that's why the switched connection would be need a different configuration.

It's nice having the guitar in full working order again.

BTW, the switch fits in the cavity with only a little gap between the cover and the switch. If the guitar was any thinner, it would have been a problem.

Weekend gigs are going to be more fun with my piezos back.

I actually never use the piezo by itself, but blend it with the mags to give some extra sparkle and twang on some songs. The piezo on the DF is a little thin sounding, more like an archtop than a flat top.

Pete Townshend style! I like it!
