FX101 Grind Rectifying Overdrive

FX101 Grind Rectifying Overdrive from Fall 1998, with original box

The FX101 Grind Rectifying Overdrive was introduced at Summer NAMM 1996, along with the FX100 Integrated Tube Even Harmonic Overdrive pedal. Sharing the same circuitboard as the FX100, the FX101 was voiced to emulate modern Mesa/Boogie-esque rectified distortion, and despite its name is really a high-gain distortion pedal rather than an overdrive pedal. In a first for DOD, the FX101 and FX100 also included a speaker emulator output jack, for plugging directly into a mixing board or a recorder. Although the FX101 was generally well-received, it was discontinued by late 1998 as DOD revised their effects pedal lineup.

• Controls: Blast (output level), Rumble (lo E.Q,), Burn (hi E.Q.), Fear (gain/overdrive)
  
  
• From the manual: "The FX 101 Grind isn't just another overdrive box, it incoporates special circuitry that adds even harmonics to the signal, emulating an overdriven tube, and then recifies it to produce a modern 'rectifier crunch sound'. With the correct utilization of this effect, all of the dynamics of an overdriven amp can be heard. The FX 101 produces tones from Hard Rock to Alternative, to the Grindcore. Since the tone cntrols [sic] 'Rumble' and 'Fear' are centered at popular amplifier frequencies, this pedal sounds like a Preamp, not a pedal. As an added bonus, the FX101 now gives you the ability to run straight to a mixing board with the speaker emulating 'SPKR OUT' jack."

  • Related circuits: FX51 (loosely based), FX100 (same circuitboard, but R27, R32, R47, C17, C19, and Q7 are missing in the FX101); DOD's I.T. circuitry was also used in a series of small practice amplifiers (including the "Grind I.T.") released at the same time.
