It's certainly provided an amazing introduction to many amps I never would have otherwise experienced. I've been spending a lot of time on the JTM45, JCM800, as well as the FAS Brit Brown and the Boogie IIC. It took about 3 seconds of playing when I got my unit a couple weeks ago to appreciate the "feel" side that several reviewers described. It's an amazing unit, and one hell of an upgrade from my SansAmp RK5 and BassFlyRig, to say the least.
In addition to the exposure to new sounds, observing creative signal chains, digging into settings from presets and Axechange site, and of course, the wealth of quality YT content have effectively become a crash course in tone.
