Additional Tone Tweakers Listings, also on Reverb

"While we normally buy, restore and sell Roland SH-2 synthesizer, this listing is just for the original SH-2 packaging shown in the photos, nothing more and nothing less. We received the last SH-2 we bought in it. We specifically bought that one for use in our studio rather than for resale. Since we have no need for this box, we figured we'd pass it along to a collector type who wants it. It’s also possible someone may want it for shipping purposes, though we always recommend packing things better for shipping, so we wouldnt recommend it for that unless it’s double-boxed. Also note that one of the foam end pieces is broken. Take a good look at the pics so you know what you’ll be getting, as always."

"This unit was tested and is working surprisingly well for a user assembled unit of its type and age. Since it's a relatively low value item, since tech time is valuable, and since most people who buy Paia gear are also into DIY electronics and enjoy doing their own repairs, we are selling it as is. This is one of the simplest synths ever made so sorting out its issues or even fully refurbishing it to be as good as new shouldnt be hard for someone who knows what they're doing. During testing, we noticed the following issues: The envelope generator attack seems too fast at maximum setting and the expand function doesn't seem to work. The oscillator doesn't track the keyboard well. We didn't attempt to calibrate the oscillator so doing so may or may not fix this -these 2700 paia oscillators typically dont track well, so this may just be due to design and not any defect. If you can't do your own repairs and don't have a good tech, you may want to trying to get in touch with Paia to see if they'd consider doing it or if they could refer you to someone who works on old Paia gear. This sale includes technical manuals and patch cables, as shown. Note: the manual colors changed a bit during photo editing, but the synth looks exactly the way it appears in the pics."

OBERHEIM OB-8 MIDI Synthesizer Meticulously Refurbished SN C31702

"This unit came to us in relatively good condition, but we fully rebuilt it to our high standards regardless, as we want our ob8s to be in top operational condition when they leave here, and to hopefully outlast all others too. This meticulous restoration took approximately 30 hours of skilled vintage synth tech time and this is of course factored into its price. Someone replaced the original keyboard with a different keyboard mechanism which works just fine, but the keys have a somewhat tighter feel than the original keyboard. There's also an added toggle switch on the front panel that's connected to the filter jack. This unit is an earlier version with 3080 VCAs as opposed to the CEM ones in the later version. We rebuilt the power supply with new capacitors, diodes and trimpots. All other trimpots inside this unit were replaced as well. We replaced molex terminal connectors, a common cause of bad connections and malfunction. We installed a new battery for the memory backup section and reloaded factory patches. We replaced all capacitors in the power line as well as the 4051 multiplexer on each voice. All pots were cleaned and lubed. All jacks cleaned, the unit disassembled and cleaned inside and out, and properly recalibrated. We also performed our special mod for improved tuning. This OB8 should make anyone looking for a fully functional OB8 very happy - you'll have a hard time finding a nicer one anywhere."

"This thing is a beast! The source of Van Halen's Jump and so many of Prince's big records.

1981 Oberheim OB-Xa (8 voice/120 programs) with MIDI

Was restored in 2015 by Analog Lab, New York City.

Specifically:

1. Kenton MIDI Kit with in/out/thru and CC
2. New keyboard bushings installed; keyboard leveled--plays like new!
3. Complete servicing of power supply--like new!
4. Replaced capacitors and ribbon cables between boards
5. LED's replaced (a few were burned out when I bought it)

The MIDI kit alone, with labor, is a 1500 dollar upgrade. All in all, more than 2500 dollars of restoration was put into this synth!

Operationally, this synth is great. All keys, knobs, switches, and so on work!

Cosmetically, it originally had a few dings that have been re-painted. There is some minor "case rash" on the rear of the synth from a previous owner that probably kept it cased for 10-15 years, but it is barely visible when you look at the rear (see pictures). If I was being picky, I would rate the cosmetics of this Xa as a 7/10, all things considered. That being said, to see these trivial defects you have to look really closely, like putting your eyeball 6" away from the face panel."

"This listing is for the Easel Command with serial no. 0710 0751; images are of the unit available for sale.

The Buchla Easel Command is the newly updated 208C in a standalone desktop form with MIDI and CV control. The 208C is the module itself for use in a Buchla 200e system.

Buchla’s own Joel Davel led the charge to create a new version of the legendary Music Easel instrument with more modular flexibility and independence, while also providing the means to easily interface with more devices, such as the various DAWs like Ableton and MIDI controllers, including the very expressive Sensel Morph. It’s still fully analog in its default configuration and provides the unique and exquisite Buchla experience with greater functionality at a lower cost.

Note: the Easel Command does not include the optional USB-A MIDI Host expander; this expansion must be purchased separately."

"So near new that the strum overlay still has the protective plastic on it.. it’s perfectly clear underneath. Brilliant! Everything else is fantastic as well.

Hologram Microcosm: Cheesy FM Synth Sounds


video upload by Hologram Electronics

"Some cheesy FM sounds from an old Yamaha Portasound going through Microcosm serve as the basis for this track. In case you were wondering, yes, the name of this synth patch is 'harp,' and we ran this 'harp' through the Arp B and Seq D presets to create ambient and synth lead sounds, respectively. We then added some glitchy guitar and drums/bass to complete this dream pop track."
