Not a fan of Deftones at all, but I really connected with Steph's modelling/amp journey. One of the best rig rundowns I have seen. After trying modelling for a long time, I went back to a JVM410 combo (sounded amazing, but got rid of it as it was too heavy) and recently bought a Revv Generator 120. Last night I took it to band practice for the first time (with a 4x12). Sounded incredible. (I was using the GT1000 for post effects and channel changing). It will be really hard to go back to the Kemper Power rack. As Steph said, there is something about the bottom end and I love the way a tube amp and cab moves air. Seriously thinking of running with just a volume/wah & tuner in front with the onboard reverb & noise gate (our music is punk). Modellers win for convenience, stereo & recording, but the organic and authoritive tone of a good, cranked tube amp can't be faked. BTW, I'll give the 4x12 a miss (too directional & heavy) and stick with stacked open back 2x12s.
