So, this last weekend our band went into the studio to begin recording bed tracks for our second album. I brought in the aforementioned amps to get my sounds. I have to say, I've always thought the PRRI was "the one" for me, but after A/B'g the two, the Vibrolux was the clear winner: much clearer, present and articulate. The PRRI sounded a bit warmer overall. A lot of people rag on the CVB, and to each his/her own, but it was a pleasant surprise. Now, my PRRI has an alnico Jensen (not the standard ceramic magnet) speaker. I'm contemplating a speaker swap, but I might just sell the thing as I have limited storage space at home and am not a pro, so one amp is good enough for me.
