Currently I am using acoustic guitar into an AER compact 60 acoustic amp. I would like to use up to 3 or 4 different instruments into the instrument channel possibly using an analogue unpowered mixer such as the Yamaha MG8/2FX. Each instrument will be used independantly of each other. Any comments regarding loss of sound quality, reduced power output or connections would be appreciated. Another option would be to use a dedicated switching device such as the Lehle 3@1 which may not be as flexible to use as the sub-mixer.
In most cases the AER would be DI'd into the PA mixer but not always, ie small cafe gigs whereby the AER's 2nd input channel would be used for microphone input. Comments gratefully received. Ta!
