I picked one of these up last year as a backup. Ended up selling my main micro head. Super clean power, and uncolored--I double on electric and upright, and trust my 2R to handle my fretted, fretless, active, and passive basses. It really lets the instruments shine through without adding anything.
Lately I've had it set up at home with my Rhodes, and it works great as a keyboard amp, as well. Totally transparent.
It's definitely a nice transparent amplifier. I've had a few second thoughts about keeping it. Your post validates some of my reasons for holding on to it! Thanks for sharing your thoughts on it!
