c.1982 MPC “The KIT” Integrated Electronic Drum Machine

Note: links to listings are affiliate links for which the site may be compensated.
video upload by riffers



via this Reverb listing

"Early British classic with that gritty, punchy analogue character.
Recently serviced: every pad triggers reliably; no noisy pots.
Original flat-pack box included. All-original hardware.
Serial (no. 242) on chassis; “Made in England” plate intact.
Set a tempo, balance the per-voice levels, and you’ve got a solid groove in seconds—no menus, no programming detours. The tactile pads invite quick ideas (fills, accents, breaks) and the adjustable pad sensitivity lets you dial in the “human” feel that helps parts sit in a song. Its distinct British analogue tone layers well with samplers/DAWs: track it straight in for gritty loops, one-shot it for kits, or re-amp it through pedals for textures. It doubles as a dependable writing click with character, so riffs and basslines arrive faster.

Fast, hands-on layout. Front-panel rotary controls are primarily per-voice level/volume (plus master TEMPO and LEVEL).

Pad feel is responsive; use the rear trimmers to dial sensitivity for dynamics or hard, machine-tight hits.

Multiple 1/4" jacks along the top panel for audio connections (see close-ups).

Power: 9V battery operation or 9V DC mains adapter (PSU not included).

Condition

Fully working. Pads all trigger; sensitivity trimmers on the underside let you set your preferred feel. Cosmetic wear from age and use: scuffs/scratches and some discolouration; a few rubber feet missing (see photos).

Included

MPC the KIT unit
Original flat-pack/knock-down box"

Selmer Companion Electric Reed Organ SN 152

Note: links to listings are affiliate links for which the site may be compensated.
video upload by riffers



via this Reverb listing

"Selmer Companion reed organ from the 60s. In tune and wonderfully “parlour-harmonium”: bright, reedy mids with a gentle breathiness on the attack, then a steady, organ-like sustain from the blower. The chord buttons give an instant drone bed with that slightly nasal, woody timbre that cuts through without ever getting harsh. Think small chapel/folk harmonium vibes—perfect for drones, hymnal pads, psych-folk textures, lo-fi soundtrack cues, and vintage pop hooks. Hear it in the demo (skip to last photo). Typical vintage tuning and keybed feel; expect minor variance vs modern concert pitch.

Features

Classic electric reed organ with compact keyboard and built-in blower/speaker
Left-hand chord section: Major & Minor buttons (C, G, D, A, F, B♭) for instant accompaniment
On/off/level control, integrated flip-up music rest in the lid, suitcase-style cabinet with carry handle 1960s/70s Italian vibe: gold fascia, cream case, and period hardware
Sounds exactly like you want a small electric harmonium to sound—see the demo"

"Serial Nº 21196

Italian-made CRB “Diamond” Cavendish Combo 30 in remarkable condition for its age. Classic combo-organ tones plus a built-in “mini-band” (bass + drums) make it a fun, self-contained writing and performance machine. Built in Ancona under CRB’s Diamond/Cavendish line.

Organ section: Flutes, Clarinets, Reeds, Strings

Presets: Piano, Spinet, Harpsichord

Effects: Sustain and Vibrato (both sound great)

Mini-band (auto-accompaniment)

Drum patterns: Waltz, March, Tango, Bossa Nova, Samba, Slow Rock, Boogie, Disco — all with variable tempo/volume; very much in the vein of early CR-series drum machines.

Bass accompaniment with automatic chords, Free 1-Finger, Memory, and chord quality switching (Major default; Minor/7th via yellow/green buttons).

External output, headphone out
Expression pedal input
Built-in speaker that’s quaint yet surprisingly punchy
UK mains power - we can include a step-up/step-down transformer on request so you can use it in your country without modification, just ask for details."

(Video) *Serviced* 1970s Wersi Entertainer Compact German Combo Organ w/ Big Rhythms

Note: links to listings are affiliate links for which the site may be compensated.
video upload by riffers



via this Reverb listing

"Back with another charmer: the Wersi Entertainer—that unmistakable 1970s/80s German home-organ vibe in a slimline, wood-cased package. Heavy, driving rhythm section (like only the Germans can), lush organ tabs, and built-in speakers for instant fun.

Set a tempo, punch in a style (March, Samba, Slow Rock, Waltz, Beat, Swing), and layer chords with Auto-Chord while you hunt melodies on the upper keys. The rhythms are steady and weighty enough to act as a “groove grid,” so song ideas arrive quickly. The on-panel balance/volume lets you sketch arrangements (pad vs lead vs rhythm) in seconds, and the bold, simple voicings sit in a mix without fuss—great for writing hooks, auditioning progressions, or tracking guide parts straight into a DAW.

Features

Voices via coloured tabs: Horn 16', Tibia 16'/8', Klarinette, Perc 8', Vibrato, Auto Chord.
Rhythm presets: March, Samba, Slow Rock, Walzer, Beat, Swing with Start/Stop and Tempo.
Onboard stereo speakers for plug-and-play use.
Rear panel: pitch trim, external amplifier output (DIN), 12V battery input, and external speaker connection.
Compact, wood-veneer cabinet with Wersi badging.
Rear panel: external amplifier out, 12V battery input, external speaker out (2–8 Ω), pitch trim.
Condition

Fully functioning: all keys, tabs and rhythms tested and working. Clean overall with light cosmetic wear consistent with age; see photos for close-ups."

(Video) *Serviced* c.1982 Clef Electronic Music B30 Microsynth Ultra-Rare UK Mono Synth

Note: links to listings are affiliate links for which the site may be compensated.
video upload by riffers


via this Reverb listing

"Super rare British analogue monosynth from Clef Electronic Music. Recently serviced and working well. Classic late-70s/early-80s panel with hands-on control: dual VCO section (with glide and sub-octs), noise, LFO, ADSR, and a great-sounding VCF with resonance. Compact keys, wood-effect cheeks and that gloriously utilitarian UK boutique vibe. Great for leads, SFX and modulated drones. Hard-wired UK mains cable fitted (240V).

Rear panel has Line Out, Headphones, and Speaker jacks. There’s also a “Sequencer” connector/jack present on the back panel; interestingly, this unit (and others we’ve seen) were built with no internal sequencer circuitry fitted, so the connector is effectively a vestigial feature."

Korg RK-100 Custom via The Packrat

images via this auction
"With the exception of one of those $3000 Zen Riffers, this is about the most unique keytar you're ever going to lay your eyes on, period. The overall shape of the Korg RK-100 is widely considered to be the most unique & attractive, and here's a fully functioning one in black, with a custom paint job by David C. Lovelace, animator & cartoonist extraordinaire.

OK fine, so it's just me typing this now & I'm playing it up just a tad. Sure, I made an animated Weird Al video for his latest album, and yeah, I made the Packrat comic strip which appeared in Keyboard Magazine a couple years ago. And then there was all of those fairly offensive-yet-popular "Retarded Animal Babies" movies seen by millions, some of which even featuring rampant keytar usage. But really, does any of this add to the value of this item? Does it even make up for the fact that I plastered a rainbow of words & symbols all over this otherwise fine contraption, rendering it somehow collectible despite its non-stock condition? I'd be a horrible salesman if I admitted otherwise. I should simply acknowledge here that there is at least a distinct possibility that these past doodleworks I have done somehow make me a public enough figure to have "fans" that might enjoy this one-of-a-kind bit of gear/artwork in their studio, collection, or attic, or just slung around their shoulder as they rokk out some Night Ranger in their local cover band. Especially if their name is also "Dave" since this moniker prominently appears on the unit's trapezoidal head.

There are a few scuffs on the back & very top of that head, by the way, but 1) no one will see them but you, and 2) they're not as bad as my high-contrast gallery image would indicate. The even better news is that there are practically no scratches anywhere else on the back (or front, not that you can tell with all the craziness going on); still as shiny as when I got the thing 15 years ago. All LED lights work fine. The battery cover is intact... so many other keytars are missing these, but not this one! Everything works great on it and is 100% functional as designed. Included is a purple guitar strap & a 9V battery (installed). I wish I had a nice, long MIDI cable to throw in (you'll need one, or better yet, a MidiJet Wireless box), but I don't have a spare, sorry! The factory 9V wall wart is not included either, not that you'd really want to be saddled with a power cable anyway! A standard 9V battery lasts a LONG time on these things; trust me. You will make it through several gigs without worrying about the power dying on you.

FUNCTIONALITY: This is a MIDI controller only, NOT a synthesizer! It does not make its own sounds! Most of you already know this, but a beginner might not. Plug a MIDI cable into it & connect with any other sound module or keyboard, and you're ready to go. You can control patch changes with a numeric keypad or program up/down buttons. There's a L/M/H octave switch, and (of course!) volume, pitch and mod wheels on the neck!"
