Two Handsome Guys Play a Rare 70s Analog Synth Through a Rare 70s Analog Delay

video upload by foleytronics fx repair

"This is Tom’s Roland SH-7, repaired after the VCO 2 tube pot failed - this thing has some serious juice. We had the opportunity to run it through Doug’s Klark Teknik DN34, a very rare bucket brigade delay from the 70s that is similar to the Marshall Time Modulator. The stereo version was used by Tangerine Dream, you can hear very similar sounds on their record 'Exit'."

Farfisa Syntorchestra Demo With an EMT 252 and Lexicon 200

video upload by foleytronics fx repair

"Here is a Farfisa Syntorchestra from the early 70s; this synth is a classic Italian string machine with some really nice sounding presets - my favorite is piccolo. We ran it with Murray’s Lexicon 200 and Brett’s EMT 252, both of which are some of the finest digital reverbs the 80s had to offer."

Controlling a Modded Vox Percussion King with an Arp 1613 Sequencer

video upload by foleytronics fx repair

"This is a modified Vox Percussion King that now has 1/4" trigger inputs for each drum sound. The triggers can be a pulse anywhere from about 2 volts to 15 volts, and the duty cycle can be anywhere from about 10% to 90%. Wider pulses alter how long the snare and castanet rolls.

This is also showcasing Benny's lovely Prime Time 93, which is an excellent match for Tom's Percussion King."

1960s Fairchild 658 Spring Reverb / Ace Tone Rhythm Producer Dub Demo

video upload by foleytronics fx repair

"This is a Farchild 658 Spring Reverb, a very cool verb with a built-in optical compressor to achieve different reverb tail lengths. All three spring tanks are active at once, and they are positioned veritcally on the grey rackmounted panel. We used Mike's Ace Tone Rhythm Producer to test it after repair and I must say... it's a lot of fun.

The reverb was sold as perfectly working, but the compressor circuit had many faulty caps, two dead transistors and a burned out lamp. It's working great now!"

Shulte Compact Phasing ‘A’ w/ Prophet-5 and Lexicon 224

video upload by foleytronics fx repair

"This is a demonstration of 'Room A' on Matt's now-fully-functional Lexicon 224, paired with Mike's Schulte Compact Phasing 'A' and my Prophet-5 rev 2. This is, in my opinion, the greatest Kraut combination I have encountered!"

The Rarest Guitar Effect Ever: EMS Synthi Hi-Fli

video upload by foleytronics fx repair

"Here we have one of 350 EMS Synthi Hi-Fli multi-effects boxes; this one showed up with a very loud buzz and, after figuring that out, no audible suboctave. It is now working perfectly and oh so much fun to play with, as you can tell by the look on Dan's face in this video and thumbnail.

We also made use of Brandt's TC Electronic 2290 Dynamic Digital Delay, which are amazing for adding depth and width to any signal."

"Here is Mike’s MIDI-fied 808 being processed by Brandt’s Spatial Expander, an awesome analog chorusing/flanging/widening effect."

"...and Mark's Lexicon 300 is now a 300L. Also on the docket in today's demo is Michael's recapped and OLEDed Roland D-550 & PG-1000 programmer, Kelly's Moog Source with new membrane panel and an honorable mention of Ramble's Oberheim Matrix-12 acting as a MIDI board for the Roland."

"This is Keith’s AMS S-DMX and Ramble’s Oberheim Matrix-12. I threw in my own Chorus Controller since there aren’t a ton of good demo videos of that unit."

Rare GEM PK 4900 Synthesizer Demo

video upload by foleytronics fx repair

"In this video, we are displaying Kelly's working GEM PK 4900, a very nice-sounding and rare synth. In addition, feast your eyes and ears on Tom's Publison DHM 89 B2, Anonymous's EMT 250 and Ramble's Juno-6. We recorded the drums in my basement a couple years ago and bounced it to the Tascam portastudio, and we're running it all through the Opamp Labs console (for sale!).

The EMT in this video has been fully done up to the 9s with all new caps, a new 128k SRAM board to reduce heat and improve stability, and of course all digital logic problems solved."

How To Care For Your Pet Minimoog

video upload by foleytronics fx repair

"This could be your 1974 Mini, completely done up by us. It has a new walnut case, NOS Pratt Read keyboard, new knobs, plus a full recap and calibration. This unit has the coveted old oscillator board, which we lightly modified to improve tuning stability between octaves. This is my favorite Minimoog I’ve ever played, but it is sadly FOR SALE as you apparently cannot pay your mortgage with them or feed them to your children. If interested, drop us a line: peter@foleytronics.com

The Carousel is Tom’s, we modified it to have individual outputs for each instrument. It pairs nicely with Chris’s other AMS 15-80s. Yes, the Carousel is normally quite noisy.

Modded Roland CR-78 - Individual Outputs!

video upload by foleytronics fx repair

"This is a CR-78 we modified to have individual 1/4” TS outputs for each drum sound. It wasn’t as simple as finding where the bass drum is generated and connecting it to a jack because we found the tone of the instrument would change without any buffering. Our solution was to create a buffer board that would isolate and amplify each of the sounds without sacrificing tone.

It’s really fun to use with a mixer - changing levels on the fly, reverb throws, different panning, you name it!

Kevin’s Omni II and RE-150

"Here is Kevin’s overhauled Omni and his working RE-150. This is an Omni from the deepest depths of hell, but really what Omni isn’t?"

Tim’s Mono/Poly and Michael’s Publison IM90

video upload by foleytronics fx repair

"Two of the oscillators in this Mono/Poly wouldn’t tune during calibration and ended up being a major pain in the tuchus. Meanwhile, this Publsion Infernal Machine had no output on channel A plus the garbled screen of ultimate despair. Figured both those out, plus recapped the tants, changed a couple broken XLR connectors and re-recapped the PSU as someone left it rather untidy. It sounds wild and is really fun to use.

Eventide HK941 and Jay’s H949

"This is a demo for Jay showcasing his now-working H949. Peter got to demo it with a very rare Eventide HK941 polyphonic Harmonizer controller keyboard, it’s a very inspiring setup!"

The World’s FIRST Digital Reverb: EMT 250 Part 1 Demo with a Sequential Circuits Prophet-5

video upload by foleytronics fx repair

"This is a 1976 EMT 250 digital reverb, one of not very many ever made. It came to the shop screaming white noise in my ear as soon as you turn it on, which ended up being a RAM issue. 12 bit (quasi 15 bit according to the manual as it converts the signal to floating point while it processes the signal, though I think they meant 16 bit as the RAM array is 8k x 16), 24 khz sample rate, probably around a 10 kHz roll off.

Part I discusses how to use it and you can hear some sound demos, part II will explore the circuitry of the unit a little more.

Steelphon S900 // Mellotron M400

video upload by foleytronics fx repair

"This is a demo of Tom’s Steelphon that got whooped by UPS - broken circuit boards, broken MDF case, no output. We took the case to be reproduced by Kent Meloy of Tunguska Guitars and in the meantime went to town on the electronics. There isn’t a schematic available anywhere, but after getting the rails back and the keyboard CV working, there was still no output. I isolated it to the filter board and realized the VCF is a Moog copy, component-for-component, so I used a Minimoog schematic to help troubleshoot the problem.

The Mellotron is mine and has undergone quite a bit of work. New pinch rollers, new motor control board, rebuilt the PSU, and fabbed a new key as one was missing."
