INTRODUCTION

The Lumitron Resonant Filter is an adaptation of the Musitronics Mu-tron III, designed by Mike Biegel

and originally released in 1972.

The Mu-tron III was the very first commercial envelope filter pedal, also called an autowah, using

optocouplers to dynamically control a series of frequency filters based on the level of the input signal.

The vocal-like effect was quickly embraced by musicians and soon became a characteristic effect of

entire genres, particularly funk. Notable Mu-tron III users include Bootsy Collins on bass, Jerry Garcia

on guitar, and even Stevie Wonder, who used it on a Clavinet.

Musitronics was sold to ARP in 1979, who produced the pedals until 1980. Mike Biegel later contracted

with Electro-Harmonix to release an updated version of the circuit in 1995, called the Q-Tron, as well as

the Bi-Filter rack unit with expanded features. The original Q-Tron was later adapted as the Mini Q-Tron,

Micro Q-Tron, and Q-Tron+, the latter two of which are still in production.

In 2019, the Mu-tron brand was resurrected with Mike Biegel once again designing new effects. The

Micro-Tron IV is an updated version of the Mu-tron III, with modernized circuitry, CV input and output,

and swappable optical modules for different reaction times and filter characteristics.

expanded feature set. If you wish the Lumitron had a lot more knobs and switches, it's worth a look.

USAGE

The Lumitron has three knobs and three switches:

• Gain boosts the signal level at the input, which drives the envelope detector as well as the main

audio signal path.

• Peak is a feedback control that sets the sharpness or intensity of the filter.

• Volume is the output volume of the effect, which compensates for high input gain levels.

• Filter (toggle switch) selects the filter type. LP (lowpass) accentuates lows. BP (bandpass) cuts lows

and highs while accentuating the peak frequency. HP (highpass) accentuates highs.

• Drive (toggle switch) selects the direction of the sweep. "Up" starts with a hi-cut and adds highs

with the intensity of the signal. "Down" starts with a low-cut and adds lows with the intensity.

• Range (toggle switch) sets the input frequency of the envelope detector. "Lo" is more sensitive to

bass signals while "Hi" is more sensitive to treble signals.
