The Maxon RTD800 features independent Overdrive and Distortion circuits combined with a dual triode tube to offer a massive array of saturated tones, from traditional tube overdrive through full-on gated metal distortion. No other tube overdrive pedal offers this degree of versatility in a single package.
Every aspect of the RTD800 has been re-thought and redesigned to provide a lifetime of trouble-free performance. As soon as power is applied to the pedal, an In-Rush Current Control circuit begins heating the tube at a very low voltage (much like a tube amp standby switch) to dramatically extend tube life. When the pedal is engaged, a charge pump circuit bumps incoming voltage to feed the tube with 12.6 VDC.
"If you ever want true distraction for the opposing world, try out the new Maxon RTD800 Distortion. The sustain and feedback made me go Funk Yeah!"
