I already have a Superblock US, which I was using with Boss Gt1000 into my PA system direct via Quiler cab sim.
I'm not a fan of IR use, it doesn't sound authentic - to my ears.
The Quilter Mach 3 however gives a great solution to American an British sounds in one very useful package.
Two channels is ideal - I switch from US 57 to Vox top boost without having to alter the EQ.
All in all a great product that I highly recommend.
Nice one Quilter. Nice one Thomann.
