This is a technique I've used multiple times with good results. I was recording electric guitar with a POD Pro, and wasn't impressed at all. I wanted to move air, so I jacked it into a power amp, and then a Marshall cab and mic'd it up in live mode (cab sim disabled). It was better, but still not what I wanted. Then I switched to a Fender wedge monitor (looking for a flatter, broader-spectrum speaker), and enabled the cab sim. Better- not perfect. Then I got to thinking- what I need is a matched combo with a wicked clean amp and a broad spectrum speaker array that won't mess with the amp and cab simulation. No way-insufficient funds. Then I looked across the room and realized I already had it! I jacked the line out of the POD into an M-Audio SBX subwoofer and a pair of SP5B monitors. Bingo!- but I had some phase issues. So- I disconnected one of the satellites, and adjusted the sub's gain to compensate. Then I asked myself, "After all of this, why am I using a cheap dynamic with a high-mid vocal boost?" I switched to a B.L.U.E. Kiwi in omni (a C414 works pretty well, also), which eliminated the proximity effect of the sub, tweaked the sub's gain to balance the tone, and it was *there*. I got the sound of the modeled amp and cab with moving air, at a volume level *far* below what would be required with a cranked up tube amp. Along with mic'ing real amps, which I also do, I've used this technique with success for several years.-Richie
