"Sound City Key Bass / Analog Organ Bass / Bass Synth / 70s.

Very rare and very cool keyboard bass.

Polyphonic, similar circuit to the combo organs of the 60s and 70s. Sounds very synth-like.

Makes some killer, yet basic, bass sounds.

Very little if any info online about these keyboards."

Indeed. I believe this is the first one posted on the site, and only the third DMI Sound City post.

FISHER SC-300K BOOMBOX Stereo Receiver w/ Removable Keyboard

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

Note the speakers are missing. You can find one speakers posted back in 2013 here.

Vintage 1980s Fisher SC-300K Am-Fm-Sw Cassette Boombox with built-in and detachable SCK-30 “Stereo Music Composer” synthesizer keyboard. Unit is in good cosmetic condition and partially working but not complete so being sold for parts or restoration.
Boombox was tested by hooking up stereo speakers with 1/8” mini jack plugs; Radio is working on all bands and heard many stations on Am & Fm with very good fidelity and volume. Didn’t spend time on the 2 shortwave bands. Cassette is not working but it just needs new belts; all the buttons are working and tape loads & ejects fine plus I can hear the motor running indicating it will work once repaired with belts.

The electronic keyboard and synth is working both with the boombox and separately with RCA cables connected to an amplifier. There is an LCD display showing the notes or keys being used. A sequencer with an eight-pattern memory stores just over 500 notes. The keyboard’s battery compartment is clean and has the cover. Same with the boombox; no leakage or bad contacts. Includes cover and AC cord. There is an internal voltage adapter for use on 120-210-240 worldwide settings.

It is being sold as is as shown, missing the speakers. Also, there are some cosmetic issues like a bend in the antenna; a plastic hook is broken on the top right that mates with the keyboard, but the synth locks down on both sides and is held securely as it is now. Also there are various scratches and rub marks on the tuner & cassette faceplate as well as the keys are discolored from age & sun but overall it still presents nicely."

Kawai XD-5 Drum Machine Digital Synthesizer Percussion Rock/FX ROM Voice Card

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

One of those obscure items from synth history. This is the first one to be posted on the site. Via the listing:

"I used this in my Kawai XD-5 drum module a long time ago and have since sold it, which I regret because it was a great sounding unique programmable drum module which sounded awesome....especially with its resonant filter which responded to velocity

I was hoping to buy another XD-5 at some point, which never happened, so I am not using this card anymore and it is of no use to me without an XD-5... so, If you have an XD-5 it could be useful to you.

It is a Sound Source Unlimited ROM card 'Rock/FX' Performance Voice Card with presets on it...64 single patches, 16 Kits and 16 output patches...if I remember correctly"

Never have I heard a phaser so lush.

Can even be controlled with CV.

About 100 were made, this is serial number 48."

Godwin Drummaker 45 Computer System

Published on Jan 4, 2019 Italian Vintage Stuff!

This is the first post to feature the Godwin Drummaker 45. You think you've seen it all, yet every year something new comes out of the annals of synth history. Be sure to check out the New Old label at the bottom of this post for more, and check out the Godwin Drummaker 32.

"The Godwin Drummaker 45 Computer System is an Italian Auto drum machine / Arpeggiator / Bass / Chord Arranger from 1976.

It was originally the rhythm section of the huge organ with the same name, but a few stand-alone units with a two octave keyboard controller were produced as well.

Very nice and warm analog sounds. It's quite complex, with many variations, less ompa-ompa compared to other similiar machines from that era.

Run through a Space Echo 301 with added chorus, echo and spring reverb."
