The AD-2 is a solid, reliable preamp for acoustic players needing a little extra something. It’s particularly good for stage use where feedback is a concern; the Resonance adds a pleasing warmth, and the Ambience is surprisingly nice. Ideal for singer-songwriters or anyone wanting a polished, stage-ready acoustic tone.
