Lately I went with 500k pots all around in my LP Standard after for years of using 300k volume pots. I kept coming back to using a 300k volume pot in the bridge but after installing some WCRs and now Wolfetone Marshallheads......I felt I should bump em up to 500k to allow the pickups to breathe which is what I also found with the WCR Goodwood. The thing you have to consider is that some guitars are naturally dark and some naturally bright so could it be best to have a 300k bridge volume pot in a naturally bright LP? It is interesting because I have done this and also had a 520k pot in my McCarty which my LP still sounded a bit brighter. Goes to prove how important the primary tone of the guitar happens to be in the end. But, I just find it important to let the pickup breathe with the 500k pot and I can always roll back the tone knob if needed. I did notice my other guitars with 500k bridge pots sounded louded than my LP when it had the 300k volume pot. Anyone else go through a similar experience or have a preference?
