hi guys, i'm having some issues with the blend pot on my yamaha bb1500a. It's only started recently, but the pot seems to be on the go. sometimes my bass will start to lightly distort.. or i get a slight volume cut. i've narrowed it down to the blend pot, because when it's happening if i press down on the pot or wiggle it around a bit it seems to make it go away. i had a quick look in the control cavity, and it seems the pots are directly connected to the pcb board. i've never really seen that before. possibly the problem is coming from a connection problem from the pot to the board?? i've tightened the nut on the pot, and that made it go away for a while, but unfortunately it's come back. and i don't think i can tighten that nut anymore! so, i need some advice here. i was thinking i should just replace the pot.. but because it's connected to that board, i'm not so confident in replacing it myself anymore (i'm happy soldering, and done a few electronics mods and such.. but i don't want to screw anything up). So not sure if thats my best option.. and even if i go down this angle, i have no idea what value that pot is, and i'd probably have to order from the net as i've looked for those kinda parts around here before to no avail. so to summarise my ramblings.. i'm needing help on a few matters; - does anybody know what value pot i would need buy as a replacement? - how hard is it to replace pots that are directly soldered to the pcb board? and any advice if i go down this angle? - do you think the problem might simply be a connection problem, not a pot fault? thanks guys i muchly appreciate in advance your collective advice! all the best, andy.
