Members MetalFam Posted April 21, 2018 Members Share Posted April 21, 2018 I have a Synyster gates custom s and the neck pickup is weak. I checked the back electronic cavity and nothing seems to be wrong. There is a singular wire that if I move signal fixes. How ever if switch to the bridge pickup and switch back. signal cuts out. It eventually fixes itself but still I switch often.Gear:-Synyster gates custom S-Sustainiac In neck-Synyster gates Seymour Duncan invader in bridge Link to comment Share on other sites More sharing options...
Members sammyreynolds01 Posted April 21, 2018 Members Share Posted April 21, 2018 You need to resolder the wire. Sounds like a loose connection. Link to comment Share on other sites More sharing options...
Members MetalFam Posted April 21, 2018 Author Members Share Posted April 21, 2018 It doesn't look like there's a disconnection though. Link to comment Share on other sites More sharing options...
Members badpenguin Posted April 21, 2018 Members Share Posted April 21, 2018 A bad solder joint sometimes isn't easy to see. Just simply resolder. Takes longer for the iron to heat up, then to do the repair. Link to comment Share on other sites More sharing options...
Members Freeman Keller Posted April 21, 2018 Members Share Posted April 21, 2018 -Sustainiac In neck While the Sustainiac's neck transducer is a "pickup" when switched that way it is a pretty poor one and is rarely used in that mode. Does the Sustainiac work in the the feedback mode? Have you replaced the the battery (Sustainiac suck battery power and when it dies you are really dead)? When installing a Sustainiac the manufacture cautions about certain wires that should not be near each other (its been a while since I installed one) - maybe moving the wires around gets them positioned in that no-no zone. Also, now that I think of it, there are several push on connectors on the Sustainiac pcb - make sure all of those are tight. Link to comment Share on other sites More sharing options...
Members Freeman Keller Posted April 21, 2018 Members Share Posted April 21, 2018 http://www.sustainiac.com/troubleshoot.pdf See page two. When I installed a Sustainiac I put a little d.c. voltmeter in the battery circuit so the player could make sure it was above 7.5 volts when he started the gig. We also made it very easy to change batteries (the guitar has an active bridge so it has two batteries - if one dies the gig is over) Link to comment Share on other sites More sharing options...
Members MetalFam Posted April 21, 2018 Author Members Share Posted April 21, 2018 What exactly do you mean by feedback mode? You mean without the battery in? If then it does. Fairly well actually. I have a super hot output bridge so it helps. Link to comment Share on other sites More sharing options...
Members MetalFam Posted April 21, 2018 Author Members Share Posted April 21, 2018 The thing is that even without the battery I have the same problem. However if I play my low e(that I mainly have tuned to d) it fixes. Link to comment Share on other sites More sharing options...
Members MetalFam Posted April 22, 2018 Author Members Share Posted April 22, 2018 If anyone can find the problem then thank you. It looks like a lightly pulled aprt wire in the second picture. The red one. They're low res so sorry.Ideas as well. Anything. Link to comment Share on other sites More sharing options...
Members MetalFam Posted April 22, 2018 Author Members Share Posted April 22, 2018 How exactly do I resolder. Do I just solder on the already soldered areas or remover wires completely? Link to comment Share on other sites More sharing options...
Members Freeman Keller Posted April 22, 2018 Members Share Posted April 22, 2018 I can't be much more helpful except to ask if this had been working correctly and somehow stopped. Obviously all the typical questions - did you do anything else, drop the guitar, yadda yadda. My experience was installing the one Sustainiac shown above - I learned a lot how it works and learned that it was pretty figity as far as getting the wiring correct. I did get your PM's - again, I don't know what I can add. Even taking it to a tech is probably a waste of time unless he is familiar with the Sustainiac - I lost money on that install but I got a heck of an education. I'm going to ask once again, did you go to page 2 of that PDF that I linked about trouble shooting the sustainer? Wiggle and tug on every wire - be very certain that the ring terminal of the output jack is switching the sustainer to ground. Calling the folks who make the Sustainiac might be helpful - I had a question and they answered it for me. Link to comment Share on other sites More sharing options...
Members Freeman Keller Posted April 22, 2018 Members Share Posted April 22, 2018 Honestly, this is no place to learn. You are soldering small wires on a little PCB - take it to someone who knows how. BP, this isn't a simple strat pot wiring job, that sustainer is a little nightmare. Link to comment Share on other sites More sharing options...
Members Freeman Keller Posted April 22, 2018 Members Share Posted April 22, 2018 What I meant about feedback mode is the sustainer switched on - in that case the bridge transducer if feeding energy back into the strings. When Its turned off the transducer acts like an ordinary (passive) pickup. On the Vee we had a standard three way selector switch (that could be your problem) That last comment about the E(D) string has to be a coincidence - it isn't related to the operation of any of the electronics.

Members badpenguin Posted April 22, 2018 Members Share Posted April 22, 2018 I myself have installed as Sustainiac system on an Alvarez Dana, and every headache Freeman has described, is true.You did say that it happens when you wiggle a wire. I assume the red wire you show in the pic? If that's the case, take it to someone who knows how to solder, and get it resoldered. Everything I have seen so far, screams a loose wire.
