I'm not trying to be patronising, it's just he perfectly described what channel 1 with maximum gain sounds like. A) the amp switch and pedal have to be set up just right initially else the pedal doesn't work properly, B) if your last amp was a single channel Laney, it would be an easy mistake to make. How low are you playing at? It needs to be 3-4 or more to come alive, otherwise it just sounds flat and muddy, without much gain.
It's all good, my last amp as a pos crate gt1200h, which I only got cause it was cheap as chips.
I've basically got it sorted out now, my footpedal is just the one from the crate, and only switched between channel 1 and 2, but i've rewired it to change channels with 1 switch, turn boost on and off with 2nd switch and switch master volumes with 3rd. and I've got gain sorted.
