I have some tweed amp clones (5E3, 5E7, 5F11) and wanted to see how they sounded with reverb and tremolo. I have a friend who allowed me to borrow his stand alone tube driven reverb/ trem unit made by a well known and respected boutique builder (street price 1500 to 1800 USD). I bought this pedal locally to compare against that unit. (300USD). THIS PEDAL SOUNDED JUST AS GOOD WITH ALMOST NO NOISE. I returned the stand alone unit. I won't be returning this pedal. Sounds very good on all the "period" settings, built like a tank, super quiet operation. If you're looking for a good pedal for recreating a lot of old school sounds, as well as more modern ones, look no further. This is the one you want.
