Picked this up on Friday & been playing around with it ever since, but still haven't actually tried all the presets.
Won't get around to really trying the effects until the expression pedal that I ordered arrives.
In my mind I was going to bring it home & compare it to my Rumble 40 (non-Studio), but as soon as I sat down & started really playing it here at home I knew there was just no way the "regular" Rumble can pull off some of these models.
Some are pretty raw-sounding, almost like a tube amp.
It sounds better with guitar than my old Rumble as well, probably due to the horn tweeter.
The looper works well, but I haven't determined its limit yet.
Having the Effects loop is a welcome addition, previously I'd been using a BigShot ABY to split my signal, because otherwise it was noisy. (ground loop)
I'd been trying these sporadically wherever I came across them & I kept telling myself I wasn't that interested. Trying to tell myself that my Rumble 40 could pull it off, LOL!
Sort of wish I'd bought it sooner, but I did get it at a discount for Black Friday.
