Much as love my AI, as wags have pointed out on this site, your ears are not in your feet, and my band is getting noisier. Even if I had a different amp, you don't get no bass (unless you've something large) unless its on the deck anyway. Accordingly, a monitor is needed, if only to hear the higher treble overtones that tell you so much about intonation. Chris Fitz uses a seperate monitor, but given the cramped conditions, hassle and amount of gear I was thinking of trying a headphone amp into the DI out and use good quality walkman 'phones which allow a lot of sound leakage from the environment (I use them at work to listen to music and still hear what's going on). Has anyone tried this? I was thinking of a Raven Labs PH1, since if this arrangement works, I can drop taking an amp to any gigs involving a house PA (this headphone amp/pre-amp has a high-quality DI out as well). Any comments?
