Excellent and versatile
A small-sized pedal with a wide range of effects. Some algorithms allow for multiple effects, contrary to what many believe (i.e only one effect at a time). That said, a second H9 would allow for far more versatility. I personally use a previously bought Hall of Fame pedal for reverb which gives me added flexibility for my needs.
I use the H9 in „pre/post“ mode which is brilliant as it automatically puts the effect either in pre or post mode relative to the amp (which you have to set in the software tool).
