New Desktop Version of the MAM MB33 Analog Retro Bass Synthesizer

It appears the MAM MB33 has been re-released as a compact, desktop synth.


"MAM MB 33 Retro, Analog Bass Synthesizer Expander, 100% Analog Signal Processing, Waveforms: sawtooth and square thomann mixable, Tune control: +/- 50 cent, Switch for Autotune, Auto Slide Function, Range: 4 octaves, 24dB lowpass filter, Cutoff frequency control (20Hz – 20kHz), Resonance control, ENV-modulation depths control, control for decay time (200ms -. 2,5Sek), Control for built in Envelope generator with thomann set, control for Accent-intensity; triggered at velocity values> = 120, VCF input socket, Socket for Midi In, Measurements : 147,5 x 85 x 49 mm B/T/H, Weight: 0,43 Kg"

It's priced at €139/£102.52. That comes out to roughly $155 US.

Update: Additional details via the MAM MB33 page:

"The MB33 Retro is manufactured completely in Germany, including assembly, mounting, casing, print and packaging – which is something, we are particularily proud of.

My thanks go to Hans Thomann and Bernd Siegismund from Musikhaus Thomann and Hari Rupp from the Music Store in Cologne, without whom this project would not have been possible. Thanks also to Artur Grönke and Harry Brandes, both of which have contributed greatly to the development of the MB33.

As with all analog devices the tolerance within the individual components is different from each other. Thus each MB33 is unique and always sounds somewhat different. This is what makes up a large part of the appeal for analogue instruments. Thus creating a much smaller device due to the SMD construction, it still contains all relevant components of the original.

The MB33 Retro was, like his predecessor, developed by Dipl.Ing. Stefan Schmidt.
Stefan Schmidt is one of the best engineers worldwide in this field , emphasized by building his own synthesizer „Schmidt“, a high-end synthesizer, used in all the top studios in the world. As with the original it was despensed of the on-off switch, since the power supply consumes almost 20 times more electricity than the MB33 by itself.

Questions and suggestions please address to „“

1. TUNE: fine pitch tuning +/- 50 cent
2. WAVE: Blends the waveforms square and sawtooth
3. CUTOFF: Sets the upper cutoff frequency of the filter
4. RESONANCE: Creates resonances in the square frequency
5. ENV MOD: intensity of an Envelope to the cutoff frequency
6. ENV DECAY: Decay time of the Envelope
7. ACCENT: is triggered via MIDI and affects Envelope, Cutoff and Volume
8. VOLUME: volume control at the output of MB33
9. MIDI-LED: alternately on incoming MIDI signals, permanently at Autotune
10. ON-LED: the MB33 is on
11. Output: Audio output of MB33
12. SCALE / OFFSET: Adjusts the intensity of the cutoff controller
13. VCF IN: Audio signal can be processed via the VCF of the MB33
14. MIDI IN: socket for controlling the sound generator of the MB33
15. MIDI CH: Set the MIDI channel (see below)
16. DEMO / AUTOTUNE: Activates AUTOTUNE (in normal operation), or the DEMO ( button down while turning on)
17. 12V AC: Socket AC adapter

  1. interesting to see the cutoff scale/offset dials right on the back panel, that is pretty cool. such a cheap price that's nice too
