This thing is very comprehensive if you have a basic setup like myself...No you can't use the 4 cable method as it has no loop...It can do everything else....

Very easy to use...Nothing but simple knobs that are clearly labeled...Plug and play...The manual is excellent and the presets give you a great start...Tweak from there....The sounds are just like the BOss pedals so I never understood why I don't see more of these around...


All my guit fiddles like this box....The OD boosts are excellent, there's compression that is ok, sound sculpting like a BBE, reverb that is passable, delay that is, well delay....There's also modulation that kinda sucks but I don't like chorus....

Overall, this thing is an all-in-one box that covers the ground of many BOSS pedals at a fraction of the cost....Worth every penny and built well to boot!


I like all the features....The OD Boost is nice...The reverbs are sufficient....They are all fine...If you have used Boss pedals before, that is the tone...For the price, you get a TON with this thing...

I don't like the fact that it has no loop...The 4 cable method would be nice with this...It also lacks usable midi...

This is a unit I don't use regularly but when I need something...It's an all-in-one BOSS pedal shop..

I'd buy again!
