Wanted to try out a PRS Studio last month. Shop assistant asked what amp I was using - as they do not stock Cornfords (Hellcat) he set me up with a Dual Rec (why?). Cleans were good but gain/distortion I can only describe as UGLY - if my Hellcat (or any of my amps) sounded like that my first reaction would be to tear out all the valves and replace them. I have heard some great sounds from Dual Recs but, try as I may, I couldn't get one no matter where I set the controls. (was using it at a 'polite' volume as there were some other customers being served, so would probably have helped to wang it up)
