Macumbista Fuzztone SoundBox

video upload by Chris Menes Sound

"A short demo of my 'Macumbista' sound box. Built at a workshop in London with sound artist, Derek Holzer a few years ago. It is a simple amplifier circuit with a speaker. The spring has a contact mic attached to it and it generates feedback when it's placed on the speaker. The touch points connect to various parts of the circuit so you can circuit bend it with your hands."

"Macumbista Fuzztone SoundBox Synthesizer Super Rare

Purchased directly from Derek Holzer of Macumbista

Rarely used and in perfect condition

Comes with Spring/Contact Mic

This was over an 8 month waiting list and they are no longer being made

Runs on a 9 volt battery

This has touch points and can be played alone as a noise source or you can use the contact mic or plug any line level source in and create

Full details from the Macumbista Website:

A new generation of the SoundBoxes is born, combining the touchable body contacts and high-gain portable amplifier from the original design with a nasty distortion with enough controls to keep your fingers busy wiggling for a long while.


* Large, high-efficiency (read: LOUD!) 12cm speaker
* High-gain input, suitable for contact microphone, electric guitar, etc. (Line level signals can be attenuated if clipping is not intended.)
* Line output
* Neutrik 6.3mm (1/4 inch) jacks on both input and output
* Four-control, switchable, extreme[!], vintage hand-selected Germanium transistor distortion
* Six “circuit-bending” touchpoints
* 9V battery operation
* Includes a resonant spring contact microphone.

This SoundBox could easily be used as a portable guitar amplifier with built-in distortion, for example, or can be used as an instrument in it’s own right to create a wide range of electronic sounds and textures.

The sound of this instrument is quite similar to what can be heard in the following video (however the video was done with the SoundBox and FuzzTone distortion pedal as separate units). Through the creative use of feedback, as well as the CHP and SQZ settings on the pedal, generative tones and chaotic patterns can emerge"
