Did a gig last Friday with vocals and my Maton acoustic guitar. The guitar has a pre-amp that blends a piezo pickup with a mic pickup. Although the guitar didn’t need tweaks to the tone itself, setting up specific compression, reverbs and perhaps some corksniffing EQ really works well on the Dwarf.
I experimented with my other (cheaper) acoustic guitar to get the piezo fizz and quack out. A simple test with a bunch of acoustic guitar IR really made it sound a lot better.
