Read an in depth interview with a guitar tech, he worked with Emmylou Harris for 11 years, as wells many other renowned musicians. His take on boutique and high end pickups is the designer winds/designs the pickup with the intention that the best sound is at full output, as connected directly to the jack. He therefore had the guitars at full volume, and would use the mixing board to cool them down if necessary. Makes sense, the pickup designer has a specific sound in mind, and wound accordingly. As far as pots go, they simply dump unused frequencies to ground. He also had some good advice to avoid scratchy pots. One is to not store a guitar with the pot where it was when done, for example turn the pot all the way left, or off. If it stays to long at a certain point, corrosion can develop at that point. Also he recommends "spinning" the pot knobs stop to stop at least a dozen times often to keep them clean. An electrical cleaner/lubricant is also recommended every once in a while. Any other tips or feedback?
