in regards to the GT SOLO -75..
The manual didn't really say which tube was for which..
I gather that 2 tubes are probably used for the effects loop, one is the Phase Inverter...as for the other two, it seems they may both effect channel 2 (scream)...Do you know, and could you explain which is what each tube is for, and how it may effect the overall sound, and which ones I really need to concentrate on to alter sound on this? I have done a bit of swapping in it, and want a little more head knowledge of what is being effected to go along with my ears...
Thanks!!!
