I've only had the pedal one day: used it through my little combo at home (Smoothie only) and at last night's gig, both with and without the Tech 21 DP-3X. The DP-3X is a two-band pedal with compression on the clean lows and low mids, and distortion on the high mids and highs. Initial result: love it. I understand compression basics, and found it really easy to dial in, partly because of the ganged attack/release. I did some experimentation and never found an unpleasant tone**. I didn't have time for a whole lot of tweaking at the gig, but did find a setting that worked well with and without the pedal: added girth while retaining dynamics. **I mostly stayed away from higher Sust settings because I didn't want too much squish. That said, I do want to try high Sust along with plenty of dry signal: I've done that with my Empress and Cali76 G-P and gotten great results. Again I've only had the pedal for a day and haven't A/B'd with my other comps so I'll let Cyrus or others handle this.
