The presets effects are really really cool, but I find it not suitable for quick playing. Maybe I still have to dig more into it. So far I've just been messing around with it, by myself.
Since it is a mono synth it's not suitable for chords and you have to be very careful about resonance. The SENS control knob adjusts the responce to your playing, but I always feel some latency between my playing and the output. I really really appreciate the DRY control, which control the volume of your uneffected signal, and I have to say the the synth volume is always pretty loud-
I still have to look more into the CTRL knob, which affects different features depending on the effect.
Above all I think it is a good quality synth for the price, and I'm pretty curious about using it with an ebow.
