The Boss GX10 is definitely very dynamic and can serve as one of the best modelers in that price range. BUT they could have made some small stuff better and easier:
LOOPER: It is definitely the worst looper I dealt with, there is no "armed" stage for recording. If you are looking forward to jam/practice, this modeler is not very friendly in this regard.
USER INTERFACE: could definitely be better, especially with few buttons available.
MIDI: No MIDI output, which is clear before buying but weird not to have it at that price range.
AMP MODELLING: Not sounding as good as other models.
PROS:
Very Dynamic
Very nice modeling of BOSS effects
IRs
It ulimately depends on what kind of player you are. However, this modeler is not for me, I will send it back and get another instead.
