Floor guitar modelling processor with the new generation of 32-bit DSP high performance 24Bit 44.1kHz AD/DA converter and True Simulation of Analog Circuits (TSAC) technology. It is based on the popular NUX MG-100 and it has its own unique features. Players who just want a convenient compact multi-effects pedal with good tone will immediately like the new designed CTRL pedal that can switch effects on/off, boost volume for solo, and set tempo for modulation and delay. The processor provides a total of 55 models (up to 8 can be used simultaneously), plus 13 classic amp models with true simulation of analogue circuit (TSAC) technology. It also offers vintage 3-band passive EQ modelling for every amp model and a 6-band graphic EQ designed specifically for electric guitar (100 Hz, 200 Hz, 400 Hz, 800 Hz, 1.6 kHz, 3.2 kHz), 12 cabinet models, a built-in drum machine with CD quality PCM sounds and 56 drum patterns including rock, pop, funk, jazz etc, and metronome. The time of presets switching is seamless and quick. The processor further offers up to 70 seconds phrase loop with sound on sound for more playability and the loop sound can be played with drum machine's rhythm beat synchronously. The AUX IN jack makes it easy to practice alone with MP3, CDs and other inputs, while large colour TFT LCD panel (160x128), graphic interface makes the overall operation easy and intuitive. The extensional pedal jack allows user to plug in an expression pedal or group switching pedal for more control. Device can be even put on the pedal board to be in the chain with other pedals. The processor provides a total of 72 presets, 36 factory + 36 user presets, and runs on batteries and AC adaptor (six AA/LR6 alkaline batteries can be continuous used for 8 hours).
