Uses the same principle as units like the legendary (and even rarer) Bode frequency shifter. Ostensibly for “Howl Reduction” but capable of some very interesting effects. Essentially, unlike a pitch shifter, a frequency shifter does not preserve the harmonic relationships in the input signal. In practice this means the output quickly starts to deviate from what is going in and extra tones are added which then interact and interfere with the source producing new harmonics and drones. As you can perhaps imagine this is what we like about these units, and why we’ve had one in the studio for years…
Serviced and working well.
Mono input and output via 1/4″ jacks on the rear.
Has some scuffs and other signs of use. See photos for more information.

"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."
"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!”
"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."
“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.”
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.
"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!"
"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."
Fantastic. From initial contact to the product landing at my door the service provided was outstanding. Safe and secure shipping, quality serviced product.
"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."
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.
"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."
“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."
“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.”
“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!”
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!
“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!”
"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."
“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”
“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”
“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.”
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!
"Soundgas offer a great service, sourcing esoteric gear that works great."
"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."
"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"
