Played for years through budget multi effects. Wanted a tube amp with effects loop without selling a kidney. Thanks April Fool’s day sale! Initially unimpressed. Thought boost made it sound nasally and still not much crunch. Decent rock rhythm, but remarkably clean single notes, especially with single coils. Multi FX predictably awful in front of it, even with amp/cab sim off.
Discovered the boost comes alive with a little more signal. Amp shines with an overdrive pedal, even if you turn the drive down and use it as clean boost. Combinations of clean, boost on the amp, and drive on/off opens up wide range of tones. Multi effects sound great in effects loop (chorus, flange, delay, even wah). Maxing the master volume makes it screaming loud, but I haven’t noticed any power amp distortion, just volume. Very responsive to guitar volume with added drives. Glad I purchased this. Gets better the more I play with it. Seems identical to studio 10 except knobs and color.
