Original - Vintage Analog Synthesized Beat -Box Sound!
Description: This Hammond Rhythm II was manufactured by Ace (printed in small leters onto the model plate) and it is almost indentical in circuitry and sound to the famous Ace Rythm, except this one is way cooler: it takes very little desktop space as housed in a "drawer" and has all of the latin rhythms separateyl accessible in form of it's red buttons. The rythm II is considered to be one of the early drum machines: All transistors, ground positive. There are no ICs in this machine and there is a lamp used for the down beat indicator. There are 3 units connected to each other: the ryhtm generator, the sound unit and the power supply. This allows to place the control unit where ever, requirign very little space and to put the board with power supply and audio circuitry elsewhere up to 20' away.
The sound of the Rhythm II is very analog and drums are very warm and liquid remiding of early ROLAND machines. Equipment that is 40 years old, even if aparentrly working, usually develops quite a few of issues (noise intermittency, distortion, fuzyness, poor sound , malfunction, etc.) - In order to take care of that his machine was completely refurbished to perform reliably and to prevent any age related issues - You will not be able to find a unit in better working condition! The Ryhtm II as assembled operates stand alone, offers a wide variety of sound and is plug and play to be used with an amplifier on stage, can be installed into an organ, or hooked up to a mixer in the electronic musician's analog recording studio! the machine provides two 1/4" outputs: direct and via the volume control.

Features: (left to right, top to bottom): Sound/Silent rocker switch, Down beat indicator lamp, Tempo potentiometer, Red buttons (Latin Rhythms): Samba, Bossa Nova, Cha Cha, Mambo, Rhumba, Beguine, Tango; Black button: "Add Bass Drum"; White buttons: Waltz, Slow Rock, Rock 'N Roll, LATINS (red), March, Fox Trot, Blad, Swing, Jazz; Rhythm Start / Stop (black round button); Volume; All rhythms can be combined if pressing in several buttons at a time - this provides almost endless possiblities of sound and rhythms.The top plate (drawer slide) can be removed if wantign a free standign unit - otherwise it can be mounted to the bottom side of the top of a desk - then it will work like a drawer that exposed the controls of the machine when open. Other: 1/4" jack for audio out - Two 1/4 outputs: one direct and the other via the volume control; Cable connects control unit with the sound module and there is a cable that connects the power supply to the main (sound) module. Currently power suppl yand main ubnit are mounted on a wooden plate for "plug and play" ready operation. AC power chord for 110 V AC - If needing conversion for a different world voltage: replace the power tsupply with a standard wall wart - 25V DC will be needed,
Condition: Good toExcellent physical condition, very clean; works perfectly. Fully refurbished for long term reliability. (see "work peforemd" below). ALL electrolytic caps in the unit were replaced! There is a slight hum due to the orignal design of the unit. With additional charges I can remedy this with a modification by re-configuring the grounding scheme, which currently is based on chassis ground.
Dimensions: (aprox.) W: 11 1/4" D: 5 3/4" H: 3 1/4" (control unit); Board w/ power supply and sound unit: 13 1/4" x 10 1/2" x 4" (if plug is inserted)
Work that went into this machine to present it as described and shown: Even though fully working when received: I replaced ALL of the electrolytic filter capacitor throughout the entire unit (3 chassis), to prevent issues that may develop due to aged components. I deoxydized and lubricated all controls, switches and internal trimmer potentiometers for long term reliability. I perfromed adjustments and calibrations, Thoroughly testested.
Lot: 1 vintage Hammond Rhythm II Beatbox Drum machine, as shown.
Price: $ 349.00 Machine Plug and Play - Ready to use! (If considering the work that went into this machine - Great value for your money!)
Super-Featured Original - Vintage Analog Silicon Transistor Sound!
Description: Not your usual Rhythm Ace beat box. This machine offers much more!
• Custom modified so that each rythms selector switch can be turned on and off at any time with ease for endless ryhtm variations by combining and changing ryhtms on the fly - perfect for life performance / composing.
• In addition to the above: Each of the precussion / drum instruments can be turned on / off via toggle switches while playing - perfect for life performance, composing or for creating this special unique ryhtm.
• This machien is stereo for amazing spacefilling ryhtms! (The Ryhtm Ace if comparing, or other similar machines are mono) Hard paned separate Hi instruments and Low instruments outputs - completely separate outputs enhance image and usability.
• Machine has 15 pre-set rythms that can be freely combined and turned on/off.
• Foot pedal jack that allows to reset to one, to silence or to let Hi-Hat play alone.
• Metronome function
• Vintage USA made Hammond Instrumet.
• Can be used on wold voltages, if replacing the exterior wall wart type power supply
This is probably the most versitile vintage analog drum machine that I ever created! You won't find a vintage machine with these options anywhere else - It is unique - Not available. It is stand alone and it is custom modified! It features separate outptus for stereo rythms - one side has the high sounding instruments and for the lower drum instruments. Fully refurbished, then custom modified so that each of the percussion / drum intruments can be turnted off separately. In combination with the 15 rhythms (- that can be combined / turned on off while it runs! -) This machine offers an nearly endless aresanl of different rythm and sound variations. Also to mention that turning instruments off and on while playing allows for sparkly life performances or to create electronic dance music. Now imagine that you add a phaser to the high output and maybe a flanger or delay to the low output. Anaolog vintage electronics heaven! This machine comes form the early days of electronics when all circuitry was built descrete with single transistors. So sound generation in this machine does not imply any ICs. There are only 3 ICs in this machine and they only help with the rhythm generation - most of the ryhtm generation circuitry is still constructed with transistors (!), which gives: A treuly early analog machine and truely sound that matches that.
This machine appear to have been manufacutred in the USA (compared to other machines of the same time aera that were Hammond branded but made in Japan by Ace, such as the FR-D2 or the Rhthm Ace).
Now to the story of how this unique instrument came to be: It was the Rhythm machien of a Hammond organ that had auto accompaniment. I made it a stand alone machine by disengaging circuitry that was not needed and by adding a custom power supply. I ended up with a buch of switches that were in the rhythm machine, but were related to functioning within in the organ, so I decided to make use of them and custom modified the machine that each switch would control one of the instruments. Also to note that the machine offered 2 separate outputs, which I routed to the back panel in form of 1/4" jacks for acess and for your enjoyment. There was circuitry for some weird foot pedal control that I made acessible with a 1/4" jack for a foot pedal. The way it operates is unusual: when depressed it re-sets the rest of the machine to the first note to be silent, but continues to beat the HiHat (if turned on) So: This cool feature adds to the versitility of playing this beast life! A truley unique machine that you would not want to miss (Most likely I will not ever make another one just like it!). Very Cool sound! Oh, I forgot: I made it's wooden casing form scratch from wood that came from another vintage instrumet form the 50's!
The sound of this analog drum machine is truely convincing vintage-electronic. Now imagine to use external effects processing on top of that! Distortion, Phasing, Flanging, Echo, Delay - It can't get any betther than this, and if seeking unique vintage electronic sound and un matched vesitility: THIS is your machine! .

Work that went into this machine to present it as described and shown: First this machine had to be modified to work independantly form the organ it came from. Then custom power supply circuitry had to bew built. Even though fully working when modified: I replaced ALL (!) electrolytic capacitors in audio and generator circuitry to prevent issues that develop due to aged electrolytics. Replaced many signal coupling caps as well. This also restores sound quality to when it was sold new. I repaired one instrument which was not working properly. I custom tweaked the circuitry of two instruments to improve their sopund, I replaced aged internal trimmer potentiometers, I deoxydized and lubricated all controls, switches and internal trimmer potentiometers for long term reliability. I re-soldered all aged solder points to prevent issues due to aged solder. I custom modified the machine by: removign and replacign all rhythm selector switches form lathed release types to holding (on/off types; this alone took more than a whole work day to complete) I removed circuitry and wiring not needed in a stand alone configuration and I modified all switrches to turn off any one of the instruments separately. I cusotm made an internal adapter that allows to still service the machine with this modification, I had to custom fabricate one switch (farthest right) and custom fit it as the original switch was damaged. I performed all electronic adjustments. I custom fabricated the machines wooden casing. Machine thoroughly testested (I used it in my studio for a while to break in the new caps and to throughly test it!). this machine is ready to perform for decades to come! If you are into electronics: It is failry easy to custom taylor the sound of this machine or to even install potentiometers that allow to alter the sound.
Lot: 1 vintage Hammond USA made Rhythm machine, as shown and described (includes wall wart 30V power supply).
Price: $ 575.00 • Buy • Machine Plug and Play - Ready to use! (If considering the amount of work that went into this machine the price does not cover the labor, that went into it.
