Thinking about switching out the tubes on my 2 Channel Custom from 6L6s to EL34s to soften the sound up a bit. Has anyone done this? I know the Guitar Sanctuary had a couple commissioned like this, but no videos / sound clips ever emerged Hoping that it will get a bit more crunch tone out of the amp. It's VERY good, exactly the right features, but I want a sound that is a bit more 'marshall-y'. Think Slash on his 'Slash' album. I know that there are a TON of different tones on that album, but would like to have my amp close to the 'Ghosts' tone.
