So far, I think the Celestion V-70 sounds really good. Seems to hold together well at higher volume, and not "ice-picky" at all. Don't know if its the speaker or the amp voicing, but the Custom DR seems tighter in the bass and not quite as bright as the DRRI, at least in the Vintage channel. I haven't spent much time on the Custom channel; my first impression is that its darker, warmer, and not as defined as the Vintage channel, which so far is my favorite. Had to ditch the tone-sucking turquoise jewel light, tho. Installed a vintage ANOS red one from my old '66 Bassman. Much better.
