MB-808 Bassqueen Roland TR-808 Clone

via Beats 'n Bytes where you'll find more pics and full details.
"The MB-808 is a clone of the famous Roland TR-808 with a Midibox step sequencer; The bassdrum has this loooong boom, the snare comes snappy and sharp, the toms go pretty deep while the congas almost self oscillate, clap and rims sound just as warm as the original and the hihats groove nice! She has swing, accent, 2 additional trigger for the classic SH-101 & 808 combination or the arpeggiator of some other synth; the digital heart of the MB-808 is the Midibox sequencer, with a rock-solid timing and quite a bunch of useful features"

HAMMOND SOLOVOX SN 81377

via this auction

"This is a vintage Hammond Solovox Keyboard-Model L. This is designed to fit with the Solovox Cabinet... This was among the earliest Music Synthesizer type units and was designed to bolt onto a piano or organ-I suppose-and provide a novel and interesting tone to the music with considerable variation. I plugged this all in and the tubes in the Tone Cabinet lit, but I could not get any sound to come from the unit-whether the problem is in the Keyboard, the complicated wiring or the speaker, I do not know. This measures about 8 by 10 by 21 1/2 in. and runs almost a full three octaves with sharps and flats."

RARE Vintage PAIA Synth Spin MkII Analog Leslie Phase

via this auction

"Official description: 'Other than the rotating speaker sound, the Synthspin can produce numerous effects ranging from very slow phasing sounds to a bubbling pseudo-reverb. Electrical inputs provide for foot-pedal control of both speed and range of the rotating effect and allow instantaneous foot-switch cancellation and bypass functions.'"

Roland SH-3a

via this auction

"Roland SH-3a. This is a very unique synth. It was Roland's first non-preset synthesizer, and was one of the few ever designed Analog synthesizers with both subtractive and additive synthesis.

Though it’s only a single oscillator synthesizer, the additive blend feature allows for the creation of some really fat sounds. And a chorus effect on the 8’ tone gives the same sound that most synth’s use two oscillators for anyway: detuned chorus.

The Sh-3 had a five stage diode ladder filter…the Sh-3a replaced it with a four stage transistor ladder filter. It’s often said that it was changed due to a Moog patent infringement…but I don’t think that’s correct since the Sh-3a is even closer in design to the Moog 904 ladder filter. Moog did sue Roland over filters…but I think it had more to do with other models. But anyway, when most people think of the Moog sound they think of the Minimoog, which is totally different…not like the 904 that this one resembles.

To me, there’s two things that really make this synth valuable. One, it has a CV and Gate interface for the oscillator that allows it to be controlled remotely. One Midi to CV convertor later and you’re suddenly sequencing this from your favorite DAW. That will keep it active in your studio line-up…not just a sideline tool. Second, this thing has a very vintage analog sound. I attribute several things to this, including the filter, and the fat additive section. But also, there’s something about the CV tracking on the oscillator that occasionally give’s you what sounds like a transient tracking error..so you get this slight random portamento sound now and then that somehow reminds you of how alive this thing is. Soft synths, digitals, and most analogs don’t do that... The Sh-3a weighs about 35 lbs"

Super Rare Vintage Chamberlin Rhythmate Drum Machine

Untitled from PHONOGRAPH VIDS on Vimeo.

via this auction
"super rare Chamberlin Rhythmate Drum Machine. This is an early model 35 with el84 tube amp, 12 inch speaker and 16 track tape loop. This IS the one! I haven't seen a Rhythmate for sale in over ten years on Ebay. These were Chamberlin's first designs and the predecessor to the Melotron. This is a must for any Chamberlin, Melotron, Optigan collector or avid fan... as am I. I hate to sell this as it was in my collection of things..."I'll never sell" but things happen, babies get made, and this too shall live on someone else's record. Here is a recording I did with it a couple months ago:
SONG SAMPLE OF ACTUAL MACHINE: MP3

It runs extremely smoothly and all 16 tracks play as seen in video. The back of the amp has controls for treble, bass, and volume as an addition to the volume knob on the top. The tempo stick is a little finicky though I have been told this is how they are. I believe it works similar to an optigan tempo which controls the voltage. 16 beautifully recorded drum tracks on to tape!"
