Yamaha AG-Stomp Acoustic Pre-Amplifier

This acoustic multi-effect functions as an EQ and DI for live and studio use. It also includes Reverb, Chorus, Delay and Feedback reduction

Yamaha's AG Stomp is a digital floor‑standing processor designed for use with acoustic guitars fitted with piezo pickup systems, its aim being to process the pickup sound so that it sounds more 'miked up'. Applications include both live performance and recording, plus there's a useful headphone output for rehearsal purposes.

There's actually rather more to the AG Stomp than mic modelling, as it also includes a chorus/delay section, limiting and onboard reverb, plus a five‑band feedback reduction system and comprehensive tone controls. Eight mic models are available, arranged as four mic types used both close up and at a greater distance, the latter settings including some nicely simulated room reflections that are quite independent of the reverb section. The whole unit is built into the same metal case as the previous DG Stomp (electric guitar preamp) pedal and is powered via an included AC adaptor
