I understand the WRHB in Tele custom RIs are not 'true' WR (because of the magnet material and construction). So, until I'm ready to pull the trigger on a more faithful reproduction, I'd like to try and remedy the muddiness of the current stock neck pup. From what I've read, upgrading the tone pot to a 500k might help a bit. However, I spoke with a local guitar tech who said it's the volume pot that I should upgrade, not the tone. What say you all?
