Gigged the PF last night using a abm 2x10 and homemade cab fitted with a1x15 BW speaker. Got the volume up, before started playing. Turned it whilst playing ending up with the volume at about 1 o clock, gain At 10 o clock and compression at about 8 o clock. Everything else on flat, hi and low buttons in and centre knob on position 3. I found certain times the sound was disappearing in the mix compared to my tour 450 head. It could be down to the poor output from my 51 squire precision. Not really found any definate setting on the net as yet. I'm guessing the gain should be brought up in line with the volume, then turned back if it starts to clip.
