Alesis GuitarFX



GuitarFX’s extremely intuitive user interface delivers Alesis’ award-winning DSP technology in the form of 80 preset/user programs, taking guitarists from high-gain distortion mayhem to subtle overdriven sounds, modulation effects, lush reverb and more.

Each of GuitarFX’s 28-bit effects and amplifier models have been carefully chosen from Alesis’ extensive DSP arsenal, and can be completely customized via simple front panel controls.

Large increment/decrement pedals and an expression pedal input make GuitarFX perfectly suited for live use, while a built-in auto-chromatic tuner provides for fast tuning on stage; battery or 9VDC operation means GuitarFX is ready to travel. GuitarFX connections include Guitar input, stereo line/headphone output, and expression pedal input.
