Hi everyone, Im Vic, and I´m using a old POD 2.0 used as a head Mesa Boogie emulator connected to the return of a MARSHALL AVT150h which works fine for metal tone and delay very simple. Im thinking now on invest in a safe distortion and equipment, such as the peavy 5150. or keep this old POD, or maybe upgrade to another new version. do you think that POD is compared to a Head? or, ignore the amplifier and connect my POD direct to the venue audio system Cheers V.
