Fly Deluxe Mag PUs Used as Passive?
« on: May 26, 2011, 01:28:47 AM »
On the Fly Deluxe 1998 model, the mags seem to be routed through the pre-amp.
I understand this is necessary to prevent the impedance difference affecting the tone of the mags when the piezo-mag mix is used.
The problem I have is that, as the battery does not have a particularly long life, there is a distinct possibility of a battery failure, when live, becoming a total failure of the guitar output.  Also the impedance difference does not have any effect anyway when using the split/stereo output mode.  The guitar is used in split/stereo mode, with mags through a guitar amp (Mesa Boogie Nomad 55) and piezo out through a D.I. box to the p.a.  The amp feeds a p.a. mic as well so there is an integrated sound when using a mag/piezo mix
I am racking my brain to improve the reliability of this setup, particularly with the battery problem, and have considered the below:

A) A mod to bring the mag output out as passive, direct to the guitar amp when the guitsr is switched to stereo mode (mono/stereo is already manual switching).  This would mean the mags would be independent of the pre-amp when switched to stereo.

B) A mod to use an external d.c. power supply (available from an effects pedal board).  This is not particulary desirable and would involve fitting a d.c. socket somewhere, probable on the bottom edge of the guitar!  This also means a trailing lead.

Does anyone have any comments or suggestions?
I have not been able to find a schematic/wiring diagram for this model - can anyone help?

The only way I was able to do the passive output was to convert to point to point wiring and the Fishman Powerchip pre-amp.

I'm not sure if it's done for impedance matching or not, I assumed that it was. Some people have bypassed the Fishman "PowerChip" (on the refined Fly models) and say that it sounds better. Sounds like the Fishman preamp probably loads the magnetic pickups a little bit. It's probably done that way with the PowerChip for convenience more than anything else, or so that a monkey with a soldering iron could do it.

In any case, if you have a pre-refined Fly, you'll have to rewire it point-to-point like Alex said.

Thanks very much for the directions to the wiring diagram - I just didn't look long and hard enough!.  I may well be making some changes so it will be invaluable.

Just a thought, your name indicates you may be part of the New York jazz scene - you may know Dave Holland, who now lives in the Catskill Mountains somewhere.  He was an acquaintance of mine from an early band in the UK.

Thanks for your reply.
 Sorry - I am new to the world of the Parker - does this mean just by-passing the existing preamp for the passive mag mod, or is the Fishman Powerchip preamp a replacement?  If it is a replacement, is it a better option?

Fishman stopped manufacturing the big PCB preamp from the original Fly back in 2004 or thereabouts. They replaced it with a much smaller preamp that goes by the name of Powerchip. It is wired in with wires instead of ribbon cables. I pointed out that the thread linked above does what you want with the Powerchip.

If that's your only concern, an alternative occurs to me: a backup battery. I took a look inside the main cavity of my 2001 Deluxe just now. I believe there would be room to drop a 9 volt battery in the space below and to the right of the board if you're willing to cut away some wood from one or both of the 'protrusions' where the screw holes are. Then you could wire it along with the main battery using a small DIP switch placed in the other available area near the lower left corner of the board. Then cut an appropriately shaped hole in the cover so you can reach in with your pick and flip the switch in an emergency.

If you do the battery back up idea, make sure that the battery can't short out the adjacent pot. [;)]
