Mu-Tron3X details

MU-FX Mu-Tron3X - Analogue Envelope Filter for guitar, bass and line level signals.
Mike Beigel, designer of the original Musitronics products now presents the newly developed Beigel Sound Labs Mu-Tron3X! The search for an original, used Mu-Tron III vintage unit is over now, because this new product has the authentic sound and response of the original product and beyond of that the new Mu-Tron3X enables whole new sonic worlds.

The Mu Is Back!
Based on the legendary Musitronics Mu-Tron III the new Mu-Tron3X goes a big step further and offers completely new possibilities. The effects unit allows both, classic auto-wah sounds for guitar and bass in the quality of its famous predecessor as well as versatile filter sounds up to strongly distorted sounds for the modern electronic music. The envelope follower works frequency- and level dependent, thus follows independently the injected signal which always results in musical tact. This pays off, if you i.e. feed a drum loop through the filter and use the controls for tonal changes in real time. The Mu-Tron always works tight and leaves a lot of room for creative possibilities.
In the filter section a new MIX function has been added, which enables an optimized mixture of the dry and the filtered signal. On top, three different colored multi-function LEDs indicate additional information from afar. However, the main novelty is the new pre-amp circuitry and a widely expanded control range, which offer a complete range of new applications. The Mu-Tron3X opens the possibilities to be used in different modes: as a classic Mu-Tron III or as modern envelope filter with pre-amp function.

Packaged in an ultra-stable, compact steel casing the new Mu-Tron3X is absolutely suitable for the stage and also offers a genuine True-Bypass function. It works with instrument levels like guitar or bass and also normal line level signals e.g. from a drum machine or synthesizer.
