Description

From AMT:

At the heart of every chorus is a short delay whose time is modulated by a low frequency oscillator (LFO). The ACV-1 uses a 1024-stage X-Vive™ high-voltage MN3007 BBD chip for its delay line. Mixing that delay back in with the original signal produces the familiar, lush sound of chorused voices in unison.

Many choruses keep the delay time fixed, but our Time knob lets you warp through the decades of chorus. Start in the middle for a tight 70’s-style chorus. Go longer for a drippy 80’s chorus and a warm slap delay, or go shorter for flanging tones.

Another uncommon addition is our Feedback knob with phase options. This lets you deepen the chorus effect and explore more exotic metallic or vocal sounds. At high feedback settings you can use the Time knob to dial in peaks and notches for resonant sounds, like a pipe or a bell. The Tone control changes the frequency response of the feedback loop to make your chorus more shimmery, or more dark and haunting. Utilizing the phase switch you can produce hollow, deep vocal sounds akin to a talk box.

Our LFO includes multiple waveforms: triangle for classic chorus sounds, sine for gooey vibrato, and square wave for rhythmic glitches and pitch jumps. The Rate and Amount controls have a huge range from subtle dimension to complete time warping madness. Or you can zero out the LFO to explore double-tracking effects, static comb filtering, and short delay.

The Mix control has a range from fully off to 100% wet, which lets you dial in subtle sounds or go all-in for true analog pitch vibrato. These settings are great for Leslie organ sounds or tape-like warble. The Tone control is even more useful here, as a way to sculpt the overall tone of your wet signal.

Finally, the CV jack rewards more intrepid sonic explorers with an even wider range of control. Increase the feedback into self-oscillation, push the LFO beyond its limit to audio rates, or drop the delay time into a lo-fi, ring-modulated soundscape.

With its thoroughly engineered set of features, the ACV-1 synthesizes decades of time warping modulation effects to inspire a whole new dimension of sounds.

TESTIMONIALS

"Yes, sure, you can find a Space Echo on eBay, but you won’t find one like this — that’s certain. I am so pleased with my decision to buy from Soundgas, and suggest you stop your search now and just send them a message. You will undoubtedly find yourself writing an ecstatic review about yours in short time."

Ben Evolo

“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."

Josh Lloyd-Watson & Tom McFarland - Jungle

“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.”

Lincoln Barrett / High Contrast

"808 is up and running. It’s hard to stop playing it. Like even to eat. Extending testing is quality control and the quality of your stuff combined with customer service is one of the reasons Soundgas is so successful in my opinion."

Brett R

Just wanted to say thank you so much for your pinch roller and echo tape. I've had a space echo for years, been sent to a shop in NYC and it never worked quite right. After installing the roller and tape, my echo works like a dream. Really incredible expertise you all have! Thank you.

Andrew Potter

“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”

Julius Bonson

"Soundgas offer a great service, sourcing esoteric gear that works great."

Tom Rowlands - Chemical Brothers

“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”

Matt Morton

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!

Dong Yun Seok

"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."

Thomas Tedesco

"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."

Koko Hiras

"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."

Ben Van Vlissingen

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.

Ben Parm

Fantastic. From initial contact to the product landing at my door the service provided was outstanding. Safe and secure shipping, quality serviced product.

Tom Johnston

"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!”

Rhett Daily

“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!”

J Yates

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!

Eric Cullen

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.

Chance Allen

"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."

Dupille Luc

“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.”

David Wrench

"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."

Tom Gossin

“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!”

Colleen / Cécile Schott

"Engaging with old gear can sometimes be filled with a lot of uncertainty, and I can't imagine what more could be done to reduce this aspect of it on top of the service you provide. Really phenomenal and I couldn't be happier."

Stephen Voinea

“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.”

Justin Meldal-Johnsen

"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"

James DLR - Sofa Sound/Metalheadz

"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."

Matthew Herbert

"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."

Hallam Kite

"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!"
