Go tube, unless you are gonna get a Line 6 , tubes are really the way to go. I wouldn't trade my Traynor for any current production amp, ( I am serious) it is the same amp as a 60s Plexi with a few minor tweaks. It is also loud as hell, not a master volume amp. You gotta attenuate it. IMO there is nothing like a cranked amp, I have a vintage tweaked Plexi RI, an early 70s Carlsbro I got from Terry Kilgore and the Traynor that was Terry's recommendation. Each one gives me shivers when I crank em up. The Crate isn't in the same ballpark as far as great rock tones go. It is a cool amp, but it ain't world class cool. If you search
Harmony Central there are Traynor Bassmaster reviews. If you get really intrigued I might know where you can snatch one up cheaper than the current Ebay prices. They are amazing amps, but it is early 70s rock tones all the way with them. My personal favorite.
