Been playing a Tone Master Twin for 3 weeks now and have yet to find fault with it at all. I've been a working pro for a long time and am old enough to have played '65 Fender Twins when they were new. The amp works well, nails the tone of a vintage '65 Twin (at some of them given they varied a lot back then), is light, has a few options to make gigging easier especially on larger stages, and it resides in a physical package that operates just like the old stuff. If it is overprice a lot of knowledgable people have been fooled because they sell out as soon as they arrive in stock at high volume retailers. Can't remember a mass produce amp that did that before. I've read a ton of critiques on line in various spots on the Internet by people that haven't tried them but sure hate the idea and denigrate and ridicule those that do. My audiences enjoy what I'm doing with the amp. Can a neo magnet speaker be built that sounds enough like a ceramic magnet model so as to be essentially identical sounding? Yeah, it can, I have the proof sitting in my studio. Players seem to not care what puffed up critics in online gear forums who have never touched them have to say. Wonder why? I saw a bunch of discussion about not including an effects loop and how that seems crazy. You mean like the effects loop on the original '65 Twins? Hey, it's there. It's called reverb and tremolo. As far as plots, circuits, waveform analysis, latency or lack thereof, expandability, speaker specifications, none of it matters if you want a light weight, great sounding amp to cover the tone of a '65 Twin. This amp will do that.
