Yes, its a different animal than the Twin and even the Pro Reverb. They say the Vibrolux has the lowest headroom out of the LVL amps. Funny though, I think my Blues Deluxe may break up a bit earlier. The Fender youtube video which introduces the Blues Deluxe talks about how it is modelled after the black face Deluxe, but its 40 watts. My Blues Deluxe manual says its more similar to a Bassman, in fact modelled after it. Makes sense since they named it a blues amp and the Bassman was made famous by blues players and the average Joe who comes into the guitar center would look at a reissue Bassman and probally think it was for bass players only. The BD has definitely got more bass, too much for a perfect Jerry tone, but no slouch at all as my demo of the BD will testify to.
They say a Pro Reverb is like a half Twin, tons of headroom, but lighter than a Twin and heavier than a Vibrolux. If you are going for a SF Fender, my advice would be go for a Vibrolux, if you can find one. This was the first one I've seen locally on CL in a few years for sure. The Vibrolux is voiced different than a twin. Its got more high end and less middy to my ears. there is no mid pot, just bass and treble. Not an issue for me. One less dial to fret over!
Vic actually was the first to spike my interest in the Vibrolux from his post on "playing without your usual gear". Then I met Scott Murawski on the street in Costa Rica the day after their (Max Creek) festival gear and we got chatting about gear. He plays one. Plus Clapton used one for many years and I love his Just One Night album, and his amp at that time was the Vibrolux.
It lives up to its reputation. I gigged with it this weekend. It was stellar.
And Griffyote, I'm with you on that one. The twin is an unyielding beast and I'm certain needs a Shakedown mod to sound right.
Thanks for the kind words BTW.
