Re: Insulation tonal differences?

moocow	Re: Insulation tonal differences? Sorry, but you guys are getting way off track here. The capacitance of a pickup is very small, around 70-100pF or so. The capacitance of a guitar cable is much larger, from 600 to 1000pF is typical. This means the guitar cable capacitance dominates the pickup capacitance, and any small changes in pickup capacitance will be inaudible. Even if pickup capacitance were important, you would need to measure the capacitance to see if it even changes when you change a parameter in your pickup. It is one thing to come up with a theory as to how the capacitance changes, but very few people actually take the measurement to verify their theories. I'd be very curious to see the capacitance numbers but so far no one has ever made measurements that show one kind of pickup construction method produces less winding capacitance than another. Anyway, I have done these sorts of calculations, simulations, and measurements and I am trying to help you pickup winders understand what is going on with your pickups. If you are hearing a difference, that's fine, but don't waste your time pursuing these capacitance theories. I've already done that for you, so if your pickups sound different because of winding, potting, etc., that's great, but they sound different for some other, unknown reason.

Even if pickup capacitance were important, you would need to *measure* the capacitance to see if it even changes when you change a parameter in your pickup. It is one thing to come up with a theory as to how the capacitance changes, but very few people actually take the measurement to verify their theories. I'd be very curious to see the capacitance numbers but so far no one has ever made measurements that show one kind of pickup construction method produces less winding capacitance than another.
