Glad to hear this. I have definite 'love/hate' with the drive pedals. As you expect, they work better with some amps as opposed to others; seemingly much better boosting a clean amp (yes, as you'd expect...dirt lessens the effect), but there is something that feels missing from some of them. Some top end glitter and cut through punch that I seem to miss. I fully accept that it might be just me. I'll have another go at the Filter Block boost, but eagerly await the rework of the Drive block.
