If you are hip to Mu-Tron history you'll know. If you're not, here is a quick history lesson. 

Mike Beigel co-founded Musitronics Corporation in the '70s. They were very successful. Then they sold the Mu-Tron product line and intellectual property Arp Instruments in 1978.

Arp went bankrupt in 1980 and all the property reverted back to Musitronics Corp. and its stockholders.

In 2006, the surviving stockholders of Musitronics unanimously assigned to Mike Beigel the sole right to represent and develop Musitronics and any of its remaining assets into the future.

In 2012, Beigel began to “resurrect and re-invent” the original Musitronics Mu-Tron product line. After the Arp bankruptcy the “Mu-Tron” and “Musitronics” trademarks were acquired in the USA by third parties. Beigel then re-named the product line Mu-FX™ by Beigel Sound Lab to avoid legal complexities.

From this great saga came this incredible pedal. Just like the original Musitronics Mu-Tron III envelope filter pedal… only better!

Mike Beigel has retained all the mojo that made the 1972 unit so popular with Stevie Wonder, Jerry Garcia, Bootsy Collins, Larry Coryell,  *inhale* Frank Zappa, Carlos Santana, Joe Zawinul, George Duke and many more. The Tru-Tron 3X is the closest you’ll find to the original Mu-Tron, because at its heart, IT IS.

The Tru-Tron 3X is bar none the best envelope filter pedal for guitar. Correction: the Tru-Tron 3X is the best envelope filter for bass, keyboards, sax or any instrument that can be plugged in!

There are several things that make this pedal special. This particular unit is numbered #92 making within the first 100 ever made. Also it has been signed by Mr. Mike Beigel right there on the side. An amazing sounding pedal that now has even more collectible status. This pedal is very clean with no marks, dings, scratches etc. On Fleek, as the kids say. This rare gem does not include the box but includes a power supply. It'll ship out swiftly and safely the next day.
