I'm pretty sure that the speed electrons travel is a constant !!

However a power conditioner can make a difference to your tone especially if you get frequent brown out / spikes etc


I have my studio plugged into an ART 4x4 power conditioner (a whopping 32 bucks) and it really makes a difference. I notice this most when people turn lights on and off in the bathroom. If I have an amp or something direct into the wall I will hear a "pop" as the electricity shorts over the light switch. With the power conditioner, all the noise is gone.
