So I have a mini-pedal board consisting of a lot of pedals (11). They are running through a one-spot daisy chain type power supply (mostly for weight/size concerns as the whole purpose of the board is as a fly rig, so want to keep as small and light as possible). I do notice a lot of high end depletion from plugging in the board. We are not talking a huge amount of cable. In fact for the test, I used very short cables. Some of the pedals are true bypass, and some are buffered. So I didn't think I'd need a buffer. But perhaps the order of the pedals, even though some are buffered, requires that I put a buffer at the beginning or end of the chain?
