Hello all. My friend and I recently got a PAS. We have practiced with it two times so far. WE have the PAS with a Mackie FX12 mixer. At our last practice we plugged the vocal mics - two shure beta 58's and then the instrument mic - shure beta 57 - into the mixer. We panned all mics hard left and plugged into channel one on the PAS. I ran my guitar through a LR Baggs para di accoustic and into channel two. My friend ran his guitar into channel three. This seemed to work and we thought it sounded good. I am not however, satisfied with the sound from the BETA 57. This mic is used for dobro and banjo. But it just seems so flat sounding to me, especially with the dobro. My question is about the presets. I had channel one set for the BETA 58's. From reading other posts here it seems the the presets can have a significant effect on sound. I realize that there is likely a variety of ways to set up. I would appreciate any suggestions on this issue. Lastly, I would have to say we really enjoy the PAS and I am sure with more practice it will sound even better.
