Hi! I play a Les Paul Special in a Princeton Reverb, and I'd like to add some dirt. I don't use any effects so far, but I think a 'second channel' would be nice. What would you recommend to add to this setup if I want to come ballpark-close to the sound of Wasting Light by the Foo Fighters? For reference; Dave Grohl is using a Hiwatt 103 and a PT100, while Chris Shiflett is using a Bassman and a AC30 combo: I love how basic it looks; guitar - small pedalboard - amp, without changing guitars and tunings. The last song, Walk, is what I'm aiming for. Although the lead part sounds phenomenal in my opinion (AC30), I'm looking for the tone of the rhythm part (Grohl). Any opinions would be very appreciated . Btw, I'm not too much of a fan of boutique because they are hard to find where I live (Europe), and they are very expensive over here. I think MXR makes some good mass-production pedals. I think the Custom Badass '78 Distortion might be able to do the trick, although I'm afraid it's a little too rough/high gain. The GT-OD sounds a bit like a Tube Screamer to me, which is always a good thing with a Fender amp I guess?
