Have had my B9-pedal for a week now and I agree with the reviews here. Adjust your technique and avoid minor 2nds in your chord voicings (I think to mimic the B3 sound it adds one or more sinuses to the note that start interfering when intervals are too small). A compressor in front of it is indeed a really good idea. Haven’t played it in my keyboard-less quartet yet, but I’d like to add my experiences from home use: - putting my MXR Micro Chorus after it in the most extreme position sounded great! Like a Leslie at top speed - playing a jazz standard like Misty or Georgia in a solo guitar chord-melody arrangement is waaaay cool! You need to indeed adjust your technique and chord voicings – I found that playing with my fingers and using my thumb as a foot-bass yielded the best results. - I do feel a slight latency (especially when you cut off the dry signal), but that gives no problems, in fact it forces your timing to be more precise and laid back and prevents noodling ;-) Great pedal!
