I have a yamaha SBG700S, with two humubcking pickups and a coiltap system (seperate volume and tone knobs for each pickup, the tone knobs are push-pull pots for the coiltapping mechanism) the neck pickup works fine, but i can't get any signal from the bridge pickup. When my pickup selector is in the bridge position, there is no signal. When it is in the middle position, i have to roll the volume knob back a lil bit to get any signal, but i still only get sound from the neck pickup. I had never had problems with it before now, and this problem happened suddenly all at once.
I took it in to my local guitar store and and i just got it back. the guy plugged it in at the shop and it still had that problem. He had switched the volume pot with a brand new one and he said he had plugged the guitar in 4 times before now and it worked fine... but for some reason this time it wasn't. (not sure if this is entirely true, he didn't seem too sure of it himself) So i got my guitar back... no charge... still busted.
I bought the guitar used and i believe the previous owner may have messed with the wiring, but i'm not an electronics guy so i don't know how it's supposed to look. Another guitar place quoted me a $45 repair charge, but i dont' wanna pay that for something that i could get a friend to do for cheaper. i havea lotta friends who know electronics, but don't know guitars well enough to work without a schematic.
any suggestions? anyone know where i could get a schematic of how the wiring is supposed to look? anyone? beuller? an ifno AT ALL would be most helpful...
do any of these schematics match my description? i can't tell. I have a gig in less than two weeks and i'd like to play it with the use of my bridge pickup.
