I want to use a set up with 2 amps with my Parker Fly. I have a Boogie for the HB side and have pretty much narrowed down my choice of acoustic amp to either the AER Compact 60, the Schertler David or the Fishman Loudbox. They all come in at about the right money and they all have the 2 channels I want. I want to use it for the piezos on my Parker Fly on function band gigs and for guitar and sax on duo gigs. They all have the DI outs so I can add a SRM 450 for the duo if required to give a bit of headroom. Has anyone tried any of these or even better had the chance to A/B any of them? I don't have a dealer close to me that carries all 3 of them or 2 of the 3 to be able to try them. Any thoughts would be appreciated.
