Introduction

Acoustic remodeling that restores body tone
The 16 source guitar type presets simulate the sonic characteristics of a variety of acous­tic guitars with different body shapes and material properties. By choosing a source guitar according to the guitar that you are using, you can share the original rich and beautiful tone of your acoustic guitar with audiences during live performances.
High-quality preamp that can be used with many pickups
The preamp was designed especially for acoustic guitars and can be used with input from piezoelectric, magnetic and passive pickups. This acoustic guitar preamp provides a range of key features, including a 3-band EQ that can be used to adjust the tone accord­ing to the environment and a super-low-noise design with a 120 dB S/N ratio and a –100 dBu noise oor.
Anti-feedback function with minimal effect on tone quality
The anti-feedback function can quickly and effectively eliminate feedback during a per­formance.
Clean boost of up to 9 dB
The boost function can reduce the volume differences of fingerpicking, strumming chords and other guitar playing techniques, as well as increase amplication during so­los.
