Overstayer Instrument Driver ID4.2

The Overstayer Instrument Driver is a dual channel line driver instrument amplifier. The multiple stages provide a wide array, from clean discrete gain to harmonics and soft saturation, from subtle thickening and high frequency and peak softening to rich distortion. Engage the pre boost and/or pull the saturation knob for oversaturation so you can distort, twist, and mangle for truly unique one of a kind sounds that just aren't possible in the digital domain.



  • Input selectable between the balanced XLR line input and unbalanced 1/4” DI input (switch in).
  • Convert instrument level unbalanced signals to +4 line level with pristine audio quality leaving your pre-amps free for microphones.
  • Use the balanced line input to re-process recorded tracks and soft synths.
  • Pre boost amplifier to overdrive the stages following while also engaging a pad on the final output.
  • Increases the drive and sensitivity of the SATURATION stage for more!
  • Provides more than 30dB of discrete gain.
  • 75Hz high pass filter immediately before the MASTER amplifier. If SATURATION is engaged a second high pass filter is also engaged within the SATURATION stage, which has the effect of shifting the harmonic content of the distortion more to the midrange.
  • 10KHz low pass filter to rolloff high frequencies.
  • Balanced XLR inputs and outputs, unbalanced 1/4" DI inputs.
  • Requires 12VDC at 1000mA supply (included).

"I've used the Instrument Driver on the Neon Trees "Picture Show", Garbage "Not Your Kind Of People", Superbus "Sunset" and the Tegan & Sara albums. Absolutely love that thing - still finding new uses for it!”
