Properly overdriving a tube amp
Posted: Thu Apr 21, 2011 2:35 pm
I've never really had tube amps that I could crank. What should I do to dial in sweet overdriven sounds? Or rather, how to get the best sound out of my amp? I've only got treble & bass EQ knobs, and I keep those fairly low. No separate gain on my amp, so it's just crank the volume and hope the neighbors don't complain.
Typical amp knob setup: (left to right: volume, treble, bass knobs)

Reference sound: Nels Cline (the dude playing the Jazzmaster) at 2:09

Granted, he's playing an amazing Jazzmaster (pretty sure his is imbued with secret magic) into either a Crowther Hot Cake or a Klon Centaur into a vintage JTM45 (pretty sure that's what he was playing on this tour, I'll check the DVD again.)
Edit: Nope, he's playing the Schroeder DB7, which Schroeder designed with Nels in mind, to be a loud 45-watt clean amp with high headroom. It uses 6L6's while my amp has EL84's. The DB7 does have a "boost" knob that may work like a top boost -- there's not enough info online to let me know. Because of this amp, I'm guessing most of the sound is from pedals driving hard. Sadly, the cameraman in Ashes of American Flags is like most music doc cameramen: he never gets close to showing the guitarist when he's doing important stuff like switching pedals or playing a solo

hence considering selling everything off to get one.
