I use it for 8 months, I had already tried the roland at 60 and 90 (bof bof); of aer (much better!, but too limiting in 60), sr tech (same product but without reverb Schertler a spring).

it's a great amp and I'm used to the gypsy sensor Schertler (good!), sometimes directly with piezo, or my stimer ... the sound is very specific on top and, more gain and reverb per channel allow for fine tuning ...
I also play it with my Rocktron live with my parker, and I can not regret my mesa ... then!

what I like most is the extreme versatility, and very powerful sound studio.

Very good quality price ratio
