i just want to pass on my comments as regards this amp ... i have used it for many functions , 1 from being a simple guitar amp with incredible sound and great sound effects , with the added colour button which enhances the sound , to using it as a PA with my desk taking a left or right out to the amp , regardless the sound and uses are great , being that instruments or vocals , have tried a full traditional Irish band thru it in a medium sound pub and no problem with overall volume and clarity , instruments that have been used with this amp , fiddle (violin) whistle Guitar obviously (ha ha) Banjo , uileann pipes , accordian , bodhran etc
i find this amp so good for smaller / medium sized gigs .. that i use it exclusively for these
the only drawback i have with this system is (because this is the battery one ) the overall weight could do with being a bit lighter , and you know its in your hands , and i would like AER to have a hole in the base of it in order to mount this on stands
other than that really amazed and happy with my purchase , yes its expensive , but the quality is there ...
