Hey Ross,
I'm surprised at the experience you've had so far with JamUp and Bias. The clicking issues are new to a recent update and will hopefully be fixed very shortly. That said, even in normal latency mode (in JamUp) it's not uncomfortable for me, though Ultra Low Latency is better... in fact, I don't notice any latency at all in that mode.

Just for fun why not download my Bias patch Marc Hvy Crunch and give it a whirl. Obviously it's tweaked for my pups (Duncan Pearly Gates, neck & bridge, on a Blacktop Strat) but I'd be curious to know how it sounds for you. The few amps I've made (if you want to try others) can be found under Marc C. I'm also quite fond of my Ctry-Blues Bias amp.
