i love the ace tone.
but i REALLY also love channel 3 tone on the tourmaster.
i finally got to "open" this amp up at a nice high volume to see how it reacts.
the GT6L6 seem to get a bit high endy in this amp when i put it from 10 watt mode to 20/50/100.
not a bad thing. but not a great thing either.
channel 4 is a mystery to me. it WANTS to get heavy, but it gets flubby after a bit. i have the bass mod schematic. i think im going to do it soon. sometimes channel 4 sounds REALLY good to me. other times, with the same guitar, it doesn't sound and feel like it should.
i asked John Ewing about another issue that im having. i'll bias this amp at 132, and a day later, it's reading 120 or lower. he thinks i have a bad power tube. if thats the case, maybe channel 4 will finally come alive.
