In addition to the sounds and controls of the ROD880, the ROD881 features a switchable Distortion mode that adds a secondary gain stage into the signal path for even more extreme drive settings. The Maxon ROD881 also features a Footswitchable Boost function that allows for quick changes between solos and rhythms. When combined with the various Drive settings on your amplifier, these features create a multitude of easily accessible tone settings at the touch of your foot. Powered by one hand-selected 12AX7WXT preamp tube, the ROD881’s Gain and Master Volume controls provide a wide variety of overdrive tones, from clean boost all the way to searing, saturated sag. Bass, Treble, and Mid Boost controls with extended operation ranges offer a limitless array of tonal options, from the classic “808” tone to extremely beefy low end chunk. All of the ROD881’s sounds are kept clean and noise-free via the rear mounted, switchable Noise Reduction circuitry with variable Threshold control and a 1:2 noise reduction ratio. Powered via a standard 9-volt DC adaptor that allows easy integration into your pedalboard or rack setup, the Maxon ROD881 offers the maximum amount of options for the distortion connoisseur.
