A Martin Guitar with tremolo and reverb? It can happen with the Strymon Flint Tremolo & Reverb Pedal.
The Flint brings together a studio effects pedal with a class combination. When you pair a Martin guitar with it, you'll get soothing, pulsating, and hypnotic effects that you never thought would be possible with an acoustic. You can see the Flint in action alongside a Martin OMC-28E and a DC-18E here.
