This Analog Synth Arrived Broken...


video upload by HAINBACH

"When I first heard the Crumar DS-2 I was enchanted: it sounds absolutely wonderful and is, like most Italian synths, a true player's instrument. I get why Sun Ra dug it so much. But it is a risky synthesizer to buy: according to vintagesynth.com it is one of "the most unreliable on the used market". And mine was no exception. The seller claimed that "you can make music with it" and he was not wrong, even though he did not say it was this messed up. I was very close to sending it back, but then I started really playing it. This is what happened.

Hainbach is the paradigm of the revaluation of outdated material and the reconditioning of machines destined for other purposes that have nothing to do with sound, although his work as a researcher is currently much broader, his technological mastery is possibly one of the most advanced of our era.

Tagwerk is an album that honours Hainbach's way of working. It is recorded on a Crumar DS-2, an early Italian synthesiser he acquired and which began to malfunction shortly after he started it up, hence the title. This album is about embracing the broken and letting it inspire you. Much of it was recorded in two days, not even daring to open the window or turn off the synthesizer for fear that inspiration would escape or that it would break completely. He recorded 22 tracks in this marathon state, and the ones on this release are the ones that survived. There is a sonic magic in that era that is unsurpassed.

Tagwerk is accompanied by a book that tells the story of this German producer and also discusses many of his machines and working techniques.

"Vintage analog EKO Tiger Junior organ with rhythm machine from 70s made in Italy.

This one is in top working condition, all keys, buttons, switches, speakers and sliders work. Cosmetically out and inside is excellent clean considering its age and shows few marks and wear tear scratches lines from signs of time and usage and some plastic bent.
It has been serviced added with audio output plug socket, also drums on rhythm machine can be customized parameters from inside panel to get for example more punch on kick bass drum, so there is lot of possibility for modifications like circuit banding to get unique character sounds."

"This unit has been fully serviced and is working perfectly. Unlike many others on the market, it's ready to play, without having to waste time and money on servicing because we already did this for you. This unit has been fully tested and is working great and sounding great. The memory is battery-backed using standard batteries (not included). Standard power supply is included, though its not the one shown in the photo (that's one of the universal adapters we use to test items in the shop). See pics.

"This unit came to us in relatively poor cosmetic condition, so our tech removed the original paint and applied a clear coat. He also fully restored the insides to make this unit work perfectly and hopefully be more reliable than other Synares out there.

We sold one other silver Synare 3 in the past and it didn't have any labels on it. Our customer asked us if we had a way for him to label the parameters, so we gave a local graphic artist the originals and had him make us a couple sets of stickers. The sticker material is different from the original, but they do the trick. We applied stickers to this unit, though we think it looks better (and more mysterious) without them. We put a lot of time, love and money into this synare and the result is a perfectly working example that's justifiably priced higher than other lesser examples. Plus, who else is selling a silver synare?!"

"Synth, pedals and power supply. Meticulously overhauled - a process requiring 16 hours of valuable skilled vintage synth tech time - and way better than the other lower priced ones out there. You get what you pay for. It's like a Rogue but without a keyboard. Instead, you play it with your feet. Or via CV gate.

Here's what our tech did to this T2:

-Removed melted foam layer between front panel and faders and cleaned up. This stuff makes a mess and takes a long time to remove. So annoying and necessary for all Taurus 2s and Rogues.
-Removed slide pots, opened and cleaned and lubed, reinstalled.
-Disassembled, cleaned inside and out.
-Cleaned and lubed key contacts.
-Removed bender and modulation wheels, which were originally yellowed, and bleached them so they'd be white again.
-Replaced felt.
-Replaced rubber feet.
-Replaced terminals for molex connectors (x6)
-Installed new wooden sides.
-Recalibrated VCOs, VCF, VCA
-Replaced original adapter with new one."

"This is a rare collectable original vintage Sequential Circuits sticker, priced high for a sticker due to rarity cause we can’t even find another one on Google. We have 2 for sale, each with its own listing.

Sticker is around 9x2”."

"This is one of the original keytars. Connect it to your Prophet-5, strap it on and show that guitarist who's boss!

Since this is generally sold as a collectors item, the price is for an unserviced, untested unit without the special cable you’ll need to hook it up to a prophet-5. Any decent tech could make that cable for you, though the parts are likely not cheap unless they already have the type of cable required. We have no idea whether or not it would work once hooked up - we have no reason to believe it won’t, but, at the very least, this type of keyboard mechanism always needs to be properly rebuilt (bushings replaced, bus bar and j-wires cleaned, etc) in order to work properly. We would normally do this work but need our tech to focus his limited time on more profitable items."

Prophet 08 PE Desktop 8-Voice Desktop Synthesizer SN 0141 w/ Custom Colored Knobs

"Knob caps where replaced with High Quality DJ Tech Tools Chroma Caps. All original knob caps are included. Last pic shows unit with rack ears and original knob caps (All Included). The serial shows 0141 which means this is 141st unit to come off the production line. Originally all Prophet 08 desktops were made with encoders instead of pots. This unit was upgraded to the PE (Potentiometer Edition) in 2012. Which is why this includes the original encoder board that was replaced with the PE board. A Savey/Techy person can probably do something cool with the original encoder board."
