I started with a DP-03 and moved up to a DP-24 last fall. I'm playing G&L Jerry Cantrell Superhawks through a Friedman JJ-100. I'm using a Heil PR30 and two SM57's for guitar tracks. The Friedman cab has Greenbacks and V30's. I've experimented quite a bit with placement and have the mics where they sound the best on the speakers. I'm happy with the amp's sound in the room, but my guitar tracks sound a bit cold, sterile, brittle. I've rolled off treble on the amp and I've experimented with pulling off treble on the tracks in the DP24 and both have helped, but I'm still not totally happy with my tracks for having $8,000 in the signal chain and being happy with the guitar rig's sound in the room. I'm considering an external mic preamp to try and warm up the sound but don't have any experience with them. Is anyone using, or has anyone used, an external mic preamp with the DP24 or 32 for this purpose? If so, does anyone have a recommendation on a budget minded unit? I'm looking at this one, which gets pretty good reviews, but I see a lot of hate online toward Behringer. http://www.musiciansfriend.com/pro-audio/behringer-ultragain-pro-mic2200 If a preamp isn't the best way to go, does anyone have other suggestions? Thanks in advance!
