Many here have heard me say that caps is caps and pots is pots. I may have changed my mind about the pots. When I built my latest guitar I installed a new set of 500K's (brand name witheld) and noticed the volume pot had a dead spot. Part way thru the sweep it would just quit producing sound. So I went back to my fave geetar store and they gladly exchanged it for me. I took it home and it measured 410K. Hardly within the =/- 10% range. I realize that every company has products that don't pass judgement, but I live in the sticks, 20 miles from my geetar store. Any suggestions for pots that don't have such a large margin of error? Are these Bournes pots worth the xtra coin?
