Yamaha FG820 with Trans-acoustic Pickup

Yamaha FG820, Mahogany Back & Side With Solid Spruce Top. Blue Sunburst. With Custom Installed Trans-acoustic Pickup. Double S1Pro with the following features. Dual-channel pickup system: combines an under-saddle piezo pickup + an on-board microphone to capture both string vibration and body resonance for a richer acoustic tone Built-in effects: includes Reverb, Chorus and Internal “Trans-Acoustic” speaker / resonance system: the pickup system can drive vibrations through the guitar body itself, so you can hear effects + resonance from the guitar — usable even unplugged. Onboard controls: knobs for overall volume, mic volume / blend, and effect levels (reverb, chorus, delay) — gives you direct control over the sound balance. Rechargeable power: uses a lithium (e.g. 18650) battery, chargeable via USB — no need for disposable batteries.
