Based on what I've been reading around here lately, I stopped at my local Guitar Center today to check out the Crate Power Block and was impressed enough by it to bring one home. After dinner, I did some A/B'ing in my den with my NOS tube equipped Super Reverb reissue and the feel & tone are so close that I think I might have trouble picking which was which in a blind test . The giveaway might be that the Crate responds faster, but the tone & feel are scarey close...at least at decent den volume. I was using my SRV Strat and the cab on the Crate was my KJL 1210 Clubowner. You guys were right.....this is a decent bang for the buck amp that will hang with tube amps costing much more. The overdrive isn't that great but clean to edge tones sound and feel excellent to these tired old ears . My next gig is a week away and it looks like my SRRI just might be the backup amp for the Crate !! More to follow as I get to know this thing a liittle better.
