I can't believe someone hasn't already started this thread with all the Paul Rivera fans I have seen on here. His work with Fender was great (mostly), but IMO his work since leaving Fender far surpasses his earlier stuff. My go to amp is a Rivera Quiana Studio 212 55/30 watt combo. Mine has a tone stack/bias mod by Voodoo Mods that was installed when I bought it used. It runs on 3 Tungsol and 2 JJ 12AX7's and 2 Gold Lion KT-66 power tubes which lend a little fatness to the Fender channel and make the Marshall voiced channel sound better than an old JTM. It is jam packed with very practical features but my favorites are the Bright, Mid Notch, Warmth, and tube buffered fx loop with adjustable send and return levels. Not to mention it is built in a two ton extra deep cab that booms with tight low end and projects better than any other combo enclosure I have heard. That being said it is a hernia causing back breaker that you wouldn't want to lug around without casters (which it comes with). The 6 spring Hammond reverb tank really makes for beautiful lush tones with perfect decay. And oh yeah, here's some pics of my tan and vintage cream beauty with her Blackface cosmetics, oxblood cloth, and beam blockers over her Warehouse cones!
