So I've once again come to that point in my life where I'm convinced that I need a new amp. I'm in a band that plays heavy stoner/sludge/doom metal. Looking for something that can go seriously LOW, FUZZY and LOUD, make me deaf in a couple of months and get me in plenty of trouble with the law until then. Something bone-rattling, that'll make the preacher crap his Sunday pants when it ain't even Sunday! I currently use a budget Bugera hybrid amp (essentially an SVT3 with a lower price tag) with a Boss bass OD in front. It's been mostly adequate and the fans seem to dig it, but I know I could do better. The amp by itself lacks... well... anything I want something all-tube, no more solid/hybrid state BS. And something with enough gain on tap that it will hopefully eliminate my need for a distortion pedal! Price isn't too big of a deal, but preferably under $2k (used). I kinda like the sound I get when plugging into a high-gain gui**** amp, but I need more low end than those offer. A couple of amps immediately come on my radar: The Orange Thunderverb 200, and the Sunn 300t (which I understand is the same thing as a Super Bassman 300? But of course, being a stoner, I'd opt for the one with the cool Sunn O))) badge on it ). Or possibly even a vintage SVT?? Problem: None of these amps are readily available to me to test out. So basically I'd like any and all input you guys have to offer on any of these amps, or anything else you think I should check out before trekking around the world to actually try these things! I play a Fender J, use a custom built 8x10, and am currently building a fEARful 1515/6. I don't plan on replacing any of this. I don't come on here too often anymore and I already know there are plenty of stoner/doom guys here, so sorry in advance if this has already been covered. Just looking for some quick answers!
