The holy grail of envelope filters, the ultimate funk pedal. It has just come back from a service/calibration - our tech knows how to get the best out of these old monsters and it's sounding superb and very squelchy, as you'd wish.
The holy grail of envelope filters, the ultimate funk pedal.
It has just come back from a service/calibration – our tech knows how to get the best out of these old monsters and it’s sounding superb and very squelchy, as you’d wish.
NOTE: We have an original 110/120v power supply for this which you can add on as an option via the box above. For UK buyers you can use it with batteries.
We’ve sold quite a few of these pedals and always have one in the studio; this one is in good working order and more than ready to continue oozing out filthy funk for the next 30-40 years.
An original Musitronics Mu-tron III for sale in full working order. This is a great analogue envelope filter (auto-wah) from the legendary Musitronics Corporation – built to withstand everything 70s musicians could throw at it – with a solid aluminium and steel case and chunky controls this vintage Made In USA pedal weighs in at over 1.5kg.
It sounds huge, fat and glorious – whatever you choose to put through it: guitar, bass or keys, it exhibits pure bona fide funk credentials. This is the real deal and is still (for us) “the biggest, baddest, funkiest envelope filter of all-time”
VOLTAGE: Will run on two 9v batteries or mains power. The original power supply option in this listing is US-only, and very uncommon. For use in UK/EU, the 9v batteries are the only option for powering the this pedal without the use of an external transformer.
Stevie Wonder, Bootsy Collins, Jerry Garcia…
Guitars, bass, Rhodes, synths, clavinet – all work well with this pedal – it instantly transports you back in time (sonically rather than literally of course) and works its analogue magic on digital sources breathing warmth and life into soft synths and samples. This pedal is what our re-amping box was made for…
These pedals have been reissued by Haz Laboratories, but though they look the part they’re a pale imitation: the originals just have that thickness and sonic mojo that the reissue units lack. We’ve tried many reissue pedals against vintage originals and while some do a passable job, most fall short when compared to the real thing. In addition, original pedals should hold their value or offer a good return as an investment.
In good cosmetic condition, with scratches and dings to the case. The face is clean with some wearing to the controls. See photos for more information on cosmetic condition.
For sales in UK/EU the price will include 20% VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number - please get in touch if you wish to buy this way.

“The perfect place to hear, learn about and then buy your most wanted piece of vintage music gear! I've not only managed to buy a rare piece of equipment I really wanted, but I have the guarantee it's been serviced, and I got it from people who are clearly passionate and knowledgeable about what they do, as well as super friendly and responsive by email. Thoroughly recommended!”
“If you are a vintage audio gear head then this is the place you have been looking for all your life. Pretty much any piece of classic or obscure kit that you are after is available here... But the clincher for me is that the gear they sell has been restored by their top techs (unless otherwise noted) which is really very important when dealing with, for example, synths from 30 years ago.”
"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."
"Excellent equipment, wonderful service. I fully recommend Soundgas to anyone in the vintage gear market and I will definitely be a return customer. The gear itself was exactly as advertised and in great condition."
"The packing job to get it over to the US was superb, and the sound and performance of my Space Echo exceeds all of my expectations. I hope to do business with Soundgas again in the future. Many thanks!”
Purchased a Juno-60 and it works beautifully. Having gotten one teched before, I knew it was worth paying a premium to get it future proofed and Soundgas does just that. Shipped professionally from the UK to USA. Appreciate their expertise and professional demeanor!
“I have bought two Moog synths from Soundgas over the past year, and I cannot say enough wonderful things about their selection of vintage products, the level of service, diligent responses to email, and expedient shipping with copious protective packaging. Soundgas is an impressive operation. My synths also sound amazing! These folks have made my vintage keyboard dreams come true in short order!”
As good as it gets. Tony, Dec and team have been incredible, prompt communication, great advice and outstanding service. It really felt like my Polysix came from a loving home.
“Imagine the perfect eBay.... with everything you never knew you wanted… and you can rest assured that your vintage and rare wobbly sound device will turn up on time and in one piece and possibly in even better condition that when it left the workshop. Soundgas - literally amazing."
Grabbed a Roland RE-201 (early edition killer pre-amp) and Roland DC-50. Absolutely STUNNING. These guys truly live up to the hype. They are meticulous in caring for the gear. Also, I have a few guitar pedal and plug-in emulations of tape-echo sounds and after plugging in the real unit I can't tell you how insane the difference is. It is incredible. Especially that tone from the early pre-amp! I am totally amazed. I am in heaven :) They made it safely to Nashville from the UK and were packed really really well! Thank you so much!! Worth every penny.
"DREAM. COME. TRUE. My music has taken me around the world a few times...and if you are like me and absolutely adore vintage gear...Soundgas is the stuff of LEGENDS. It's the shop that people like us search for our whole lives- fantastic and rare selections, and the technical know-how to repair and or mod these vintage items to get them into shape to flow with your modern setup."
Fantastic. From initial contact to the product landing at my door the service provided was outstanding. Safe and secure shipping, quality serviced product.
I have been buying vintage stuff for a long time from resellers/stores/techs. I've never been so surprised and pleased after opening! Just received a Roland RE-201 and VX55 mixer, they look and sound amazing! Thanks to Tony/Declan for the service and the Soundgas team will be back!
"Soundgas offer a great service, sourcing esoteric gear that works great."
"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."
"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."
“I purchased a completely overhauled vintage valve Binson Echorec 2 T7E modified with varispeed, wet-only output, and a new paint job from Soundgas in early 2018. Tony and his team did an amazing job during every step of the purchase”
"Soundgas has an unbelievable selection of the cool, old stuff that’s hard to find. Tony knows his stuff and goes out of his way to make sure the transaction is a smooth one. Thanks guys!"
"Soundgas provided the absolutely top service in terms of item quality as well as service and communication. Shipping was fast, packing was top notch. These people deserve the best reputation they already have. Many many thanks, guys."
"Still in shock! Can not believe how good the seller is. This product was inspected, and shipped from the UK to the USA quicker than orders from my home state. Highly recommend these guys."
“If not a new language, then at least a very challenging, old dialect that will take me some time to assimilate. I’ve been waiting a long time for the challenge. Thank you @soundgasltd, she’s a beaut...and nobody prepares and packs like you fine folks.”
"When you are spending big money of vintage gear it's nice to have the confidence of impeccable service, sales and support... some of the best in the industry! Impeccable people, incredible equipment… my poor poor fiancé"
“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”
“I’ve bought a number of items from Soundgas recently, and have been really impressed with their service. It takes the stress out of buying vintage gear to know it’s been properly (and faithfully) serviced or restored. Their after-sales service has also been exemplary. Highly recommended.”
