I try to test a Cornford in Holland, but you don't see them a lot. At least not where I live. Ritchie Kotzen gets great tones out of his Cornford.
Funny what you mention about the booster. I have the same experience with my Toadworks Dual Boost, when I engage it it seems the guitar is straigth in the amp, although the signal goes through eight pedals. I think it is buffered and compensates the loss of signal throught the effects and cables. The booster provides more punch too.
