I have some Carvin amps.
A XV-112 combo, second generation (with EL34). The first generation was voiced slightly differently, and used 6L6.
This is a very capable amp, the combo version of the X100B (they share the same schematics).
This is a dual channel (+ boost) tube preamp followed by active stages (op-amps) : active voicing network followed by a 4 bands active "tone-stack". Then a graphic equalizer. Reverb is usable. The power amp is all tubes.
The equalizer is not very neutral with all sliders at "0".
I like this amp.
A Quad-X preamp. The design is an extension of the X100B/XV-112/XV-212 technology : tube preamps surrounded by an amazing number of op-amps. Never seen that many solid-state stages in a tube preamp !
4 channels, including a hi-gain channel using 11 (eleven !) tube gain stages.
Good "modern" cleans, a bit clinical. I found the overdrive definitively voiced for modern hi-output pickups. It sounded quite good with my Jackson (Duncan pickups).
The equalizer is of much better design than in the X100B, electronically speaking.
There is a usable spring reverb, a noise-gate, and a sophisticated, per channel, effects send-return system.
Oh, and MIDI switching (but not MIDI control, like in the Triaxis).
Seems very well built.
I used it with a Simul-Class 295 power amp and the power section of the XV-112. Eminence Legend or JBL E120 speakers.
For me, overall, it lakes a bit dynamics, and I'm not fond of the general voicing.
I'm definitively not a hudge fan of this preamp (I tried very hard !), but 90's hard-rock/metal fans may really love it!!!
I have a Triaxis and a Quad Preamp, so comparison is tough for this Carvin preamp !
One of these days, I will try again to love it.
A Carvin Legacy, first version. This unit had recurring faults, and have been butchered by a "professional" repairman. The owner finally sold it for cheap, and I fixed it.
Sounds exceptionally good, really. Very good cleans. Soaring, fluid distortion, without any harshness.
Some people says it has a Dumble flavor. As I don't have 30k for an amp, I can't tell for sure... :mrgreen:
The Legacy circuit is said to have been tweaked for almost one year under direct control of Steve Vai.
Great amp, not necessarily for Steve Vai fans !
P.S. I changed a number of pots (to audio taper), to get a much more progressive volume/reverb control.
Cheers !
