The speaker cabinet is a Rivera C212 loaded with 2 Celestion G12T-75s. I know they're bright speakers, but I've used them before and I'm positive the sound I'm hearing is not the fault of the cabinet.
I used ElectroHarmonix tubes.
I've been keeping the amp on its lowest power mode in stereo (triode power, the lower power setting on the front switch). I tried the gain knobs pushed and pulled in all combinations, usually with bass around 6-7, mids 8, treble 4 (and tried it at 0 to no avail) and it gets the same sound. When I turn down the presence, the sound gets muddier but remains buzzy. I already took my amp to a guy who's supposed to be a "specialist" and all he could do was bias it and charge me $80 for that and inspecting/testing all the amp's functions.
Vai/Satch sound is what I want from the distortion channel, but that's just not what I'm getting
I'm getting Squier plugged into a distortion pedal then into headphones kind of sound. Something has got to be wrong.
I phoned Paul Rivera Sr. and he said he didn't know what I was referring to exactly. He thought the cabinet might be voiced too brightly for my tastes (since my other amp is a Mesa Mark IV, mostly a dark sound) but I'm positive that isn't the problem. I get a near identical sound plugged into a Recto cab. Maybe I'll call back again later to see what else he might be able to do
Vaijem when Paul Rivera rebuilt your amp did it sound drastically different? I live in Canada so to send the amp to him would be very expensive. I'm thinking now I might just be better off selling the amp and trying to cut my losses.
