This has been bothering me for close to a year now and I've finally decided that enough is enough! Basically, the tone control on my P bass goes from completely off to completely on almost instantly. There is no 'middle ground' with the tone control and it bothers me to no end that my only options are bassy with no highs or highs with no bass. I'd like a nice middle of the road, grindy sort of tone, and this just ain't cutting it. My question is what can I do to fix this? Is there any specific part I can buy to fix this issue and give my tone control a smoother slope?
