Introduction
Acoustic modeling restores body tone
Presets for 16 body types and 28 model types simulate the sonic characteristics of a variety of acoustic guitars with different body shapes and material properties. By choosing a body and model according to the guitar that you are using, you can share the original rich and beautiful tone of your acoustic guitar with audiences when you perform live.
High-quality preamp can be used with both pickups and mics
The preamp was designed especially for acoustic guitars and can be used with piezoelectric, magnetic and passive pickups. In addition, you can connect a condenser microphone to the XLR mic input, which can provide phantom power, and mix that signal with the pickup signal to shape the sound. This acoustic guitar preamp offers a full array of features. The 3-band EQ can be used to adjust the tone according to the environment. The BALANCE knob can be used to set the ratio of the original sound (DRY) and the sound after the effects (WET). The super low noise design provides a 120dB S/N ratio and a –100dBm noise floor.
40 types of acoustic guitar effects
The 40 effects, which have a focus on chorus, delay, reverb and other spatial effects, can make acoustic tones even more beautiful. Other effects include a compressor that suppresses input peaks and evens the volume level, an air effect that simulates the sense of space from room tone and a detuning effect that creates a sound like a 12-string guitar. You can use any 2 of these effects together as you like.
Anti-feedback function with minimal effect on tone quality
The Anti-feedback function can quickly and effectively eliminate feedback during a performance. Just step on the Anti-feedback switch to automatically detect the frequency that is causing feedback and surgically apply a steep filter to cut that frequency band. The Antifeedback function can handle up to 3 different frequencies that are causing feedback.
Clean boost of up to 12 dB
The Boost function can reduce the volume differences of fingerpicking, strumming chords and other guitar playing techniques, as well as increase amplification during solos. You can also adjust the sound when the boost is active with the TONE parameter.
Terms Used inThis Manual
Patch memory
The ON/OFF status and the parameter settings of each effect are stored as ”patch memories”. The
