Mu-FX BoosTron 3

Based Upon a Trio of Classic Designs
The NEW Mu-FX Boostron 3 is three pedals in one… and three you might never want to turn off!

Stage 1: Based upon an Alembic Stratoblaster clean boost
Stage 2: Based upon a Musitronics/Dan Armstrong Orange Squeezer compressor
Stage 3: Based upon a Pro Co RAT distortion

The Alembic Stratoblaster is a FET preamp that provides a clean boost. The original product was a retrofit guitar input jack with the (battery powered) effect built in – controlled by an on/off switch and a small adjustable trim pot for the desired amount of gain. The Musitronics/Dan Armstrong Orange Squeezer is a very simple and distinctive sounding compressor. The original product was a small cube that plugged directly into your guitar (…unless you had a Strat!), powered by a 9V battery and was controlled by an on/off switch as well as an internal trim pot for setting the desired output level. The Pro Co RAT is an LM308 op-amp distortion that ranges from bluesy overdrive to full-out fuzzy distortion. The original product was a moderately sized effects pedal powered by a 9V battery.

The Mu-FX Boostron 3 provides added functionality to these classic effects all bundled in our “mini-mu” housing. Made in the USA, this new Mu-FX product combines visual and sonic cues from the past with a thoroughly modern, pedal board oriented approach.



    • Boost controls the output level of the effect
    • Blaster On/True-Bypass switch determines whether the effect is on or off (true-bypassed)
    • LED indicates volume by brightness
    • Bright controls the amount of treble boost
    • Juice controls the input level to compressor (the amount of “squash” to the signal)
    • Output controls the output level of the compressed signal
    • Gain controls the amount of gain in the distortion circuit
    • Bass Flat/-/+ Switch
      • Flat position is the normal tonality of distortion circuit
      • – position cuts bass frequencies from the distortion circuit
      • + position boosts bass frequencies to the distortion circuit
    • Level controls the output level of the distorted signal
    • Comp/Exp/Dist Mode Switch
      • Comp – 2 diode symmetrical distortion (a “limiting” distortion)
      • Exp – Single diode asymmetrical distortion (provides more headroom for dynamics)
      • Dist – LED + Single diode distortion
  • SQUEEZER footswitch determines whether the effect is on or off (true-bypassed)
    • LED
      • Red – Off
      • Blue – On
  • SLACKER footswitch determines whether the effect is on or off (true-bypassed)
    • LED
      • Red – Off
      • Dark Blue – Comp
