Really clean HAZ Laboratories Mu-Tron III+ envelope filter, serial #5308. Fully tested and working great.


Classic Mu-Tron-style envelope filter with LP/BP/HP modes, Up/Down drive, Low/High range, and Peak/Depth controls. Lots of different sounds available depending on your playing dynamics and settings.


Includes:


* Original box

* Original operating instructions

* Very clean enclosure and faceplate

* Fully functional switches, controls, input/output and footswitch


The pedal originally had two damaged PCB traces that caused signal issues. Those traces were repaired with two small jumper wires and the pedal is now fully functional. Internal photo is included so the repair is completely transparent.


These HAZ Mu-Tron III+ units don’t come up nearly as often as modern envelope filters, especially this clean and with the box/documentation.
