I tried out a CAA OD-100 standard yesterday with 5881s and I think this is going to be my next amp. The cleans are so good! Fenderish but big and fat and with the boost it provides really nice overdriven fenderish tones that I guess would be classifed SRVish. I initially didn't care for the OD side because it brought on so much trebly highs but after some knob twisting and pretty much maxing the bass knob I really got to sound great. I'm not a high gain guy but I was to able to pull up really nice crunch tones on this channel by keeping the gain low and cranking the level. Can anybody comment on the difference between the standard with the 5881s and the el34s. I probably wouldn't care for the SE mod because I don't use that much gain. Also has anybody compared the standard with 5881s to the new Classic model (which has el-34s)with less gain? I've heard the clips from indoor storm but it's hard to really tell. The cleans in that clip didn't sound as fenderish as the one I tried. Anybody have one they want to sell?
