I looked at that amp and ended up with the ProBlock 200 (I am intrigued by their 2 x 8 speaker cabinet which is way overpriced).
In the mean time though, it is a backup to my classic tube stuff and am still getting familar with dialing in a great sound with pedals.
I use to use a Crate PowerBlock and I sold it when it was working but it always felt cheap (not so with the quilter stuff).
Post some live videos when you get a chance in a live setting. I am curious.... take care
I also use the Pro Block 200 but strictly as a poweramp with an Ethos preamp and an FX8 for efx. Haven't even turned the tube stuff for several months.
