Greetings Talkbassers! I'm Jordan, and I'm actually a guitarist. I'm here because my bassist is looking for a new amp and since he only uses the internet for porn, I thought I'd do a little research for him. A bit of background - my band plays... I guess the best way to describe it is a mix of QotSA with some Sleep, Zeppelin, and jam music thrown in. Spacey stoner metal. Anyway, I run a 68 Bassman into the matching 2x12 (Eminence C. Rex and Texas Heat) I usually run that somewhere between 4 and 6, depending on how clean I'm feeling that day. I get my distortion from a Basic Audio Tri/Ram muff. I play most of our songs tuned down to C# Standard, although I do have a guitar that I use for a few songs in E Standard. My bassist just got a 70's Ampeg 8x10 and he's looking for a nice tube amp to go with it. He wants an Ampeg SVT Classic, but for $1800 we can do better than a Vietnamese amp that weighs 80 ****ing pounds. Enter the AD200B - seems like a much better amp. Let me just insert this here - my bassist is looking for a single channel, simple all tube bass amp. A bit more on the modern sounding side, but not totally modern. A good loud clean tone that can get a bit broken up would be ideal, but it should be able to take a fuzz or two really nicely to mesh with the music we play. Whatever he buys also must be new, as he's going to finance it. Durability and reliability are very important to both of us. So, the AD200B looks like it pushes all of the right buttons. Simple amp with a full tonestack, all tube, passive/active inputs, slave out (always nice) and ruggedly built (UK instead of Vietnam) without being heavy as hell (under 60lbs) and Oranges just look awesome. So, any opinions on the Orange? Any recommendations for something better? I've heard that the AD200 is best used with a cab with high efficiency speakers. Would the 8x10 we have be enough for the orange to keep up with my guitar rig? Oh and he's currently using a GK Backline 250. Thanks guys!
