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).


Rack Saturator under $1000

...not sure if I need a preamp or dedicated saturator. One of the best options suggested by these threads is an Overstayer iD4, but I can't find one for sale anywhere. There's tons of great options in the $2-3k range (Fatso, Silver Bullet), but I'd like to come in under that for now and upgrade...

That list is absurd and is just going to be a distraction if you actually want to make music rather than just be a collector of things. I encourage you to slim down to just a few good ones if you want to be musically productive.
