Best tone caps for GFS Dream180 pups?

Post by countertext » Sun Jul 20, 2014 9:51 am

Bear with me here - I need your help.

Ok, a few months ago, I asked about help with repairing an old Peavey Milestone (look here if you must), and the consensus of the few that commented was "that thing is a mess". After closer examination, I figured out that some of the components were melted from overenthusiastic soldering anyway.

The repairs were stalled for financial/time reasons for a while, but now I can round up the parts I need. I considered taking it to my local repairperson to have it rewired, but you know what, BABY TIME IS OVER. I need to just wire it myself.

The axe has two humbuckers, and I couldn't get any signal out of one of the coils of one of them, no matter how I tapped or metered or fiddled, so I bought two GFS Dream180s. Cheap enough, what the hell, if it turns out the original pickups can be salvaged somehow, maybe I'll reinstall them later. The switches and pots have been resoldered to the point of failure in a couple cases, and disfigurement in others, so they'll be replaced tomorrow when I go to my local parts place.

The original setup was: master volume; neck rotary coil cut; bridge rotary coil cut; 3-way pickup selector; 2-way phase switch (on bridge pup).

Realistically, though, I wouldn't mind just wiring it more simply: master volume; neck tone; bridge tone; 3-way selector; phase switch (bridge).

Please, oh please, can someone here sketch a wiring diagram that is legible to a novice for this setup? I would be eternally grateful if you could.

Anybody know of an online stash of schematics that might have what I need, then?

Holy crap, they got right back to me with the original schematic - good call, Grandmaster!

One vote for Peavey Customer Service!

Yea,nothing but praise for peavey customer support.Also I looked at the other theead you linked.The older peavey guitars mostly had the tone knobs wired to act as a coil split/tone knob.It's simple to wire once you see the schem.Pretty usefull imo.I don't know how framiliar you are with how it functions but there are a few youtube clips explaining it.

Thanks, Grandmaster. Now that I see the schematic, it makes sense and seems easy to do. I honestly assumed that either the pickups or the pots had to be special for that to work, so I was planning on just running tones. But I've changed my mind and now plan to preserve the honor of the noble beast with an original wiring scheme.

Your speaking my language.I am a fan of older peavey gear.I also assumed i'd need specialty components the first time I was asked to fix an old t-27(simmilar wiring to yours,no phase switching)
And when I got the schem had a face palm moment.

It's unfortunate no one suggested contacting Peavey earlier.

Oh, wait... :)

Ok, that's enough from you. I never claimed to be the sharpest tool in the shed.

??? Charming.

It was a joke, hence the smiley.

A hammer doesn't need to be sharp.

I was jokin', too. Don't know why I didn't email Peavey the first time. Just overlooked it somehow, I guess.

Regardless, in my meager spare time I've wired up everything but the pickups and jack. I'll do that tonight and report back on whether I was successful... or still a total failure at soldering.

Wired this up last night according to the schematic, but everything came out screwy with the switching... so I sent a pm to andy_tchp for advice, and he kindly pointed out that not all pickups have always been manufactured with the same damn color wires. :fp: I think I kinda knew that, but forgot. I showed up at a Peavey party and tried to speak GFS, so they kicked me out. Or vice versa.

Either way, another attempt tonight! I guess that amazing picture I was going to post of how clean my wiring job is compared to how I received it is never going to happen. Such a mess I've made... :unsure:

Re: Why would a 3-way pup switch not work in the middle pos?

Post by countertext » Wed Jul 23, 2014 7:23 pm

andy_tchp's solution helped make my individual humbuckers work perfectly... but when the pup selector is in the middle (both) position, I get nothing. Is there a common mistake I might be making for that to happen? I've wired it precisely to this schematic, save for switching colors to match the new pickups.

OK, I'm just going to wire this thing up straight - two hb's, three-pos toggle, one vol, two tones, one phase switch.

What do y'all think is a good cap value for the tone controls?
