This is a rare Mi Effects Super Crunch Box. The only included item is the main unit, and it's in almost perfect condition. Here's the product description: ■ This is the ultimate distortion pedal, further "modified" from the hit "Crunch Box Distortion," meticulously tuned to emulate a stack amp. ■ An internal 18V boost circuit is incorporated to achieve a large headroom, creating a more defined drive tone. To improve playability, the "PRESENCE" control, previously an internal trimmer, has been placed on the front panel, allowing for a wide range of sound creation in conjunction with the TONE control. ■ Additionally, two new switches have been added: the "LO/Hi Gain Select Switch," which creates two different gain stages, and the "3 Point Comp Switch," which controls compression by selecting clipping. The sound achieves further saturation while reproducing a creamy and rich mid-tone.
