MAM FreeBass 383

FreeBass FB383 Image

Another monophonic analog TB-303 clone! The FB 383 is a re-packaged version of the MB 33 with a special front-panel design as part of an exclusive deal with Turnkey music shop UK. Just like the MB 33, the FB 383 offers all the same basic sounds and controls as the original TB-303 in a 1-unit rack module. It has just 8 basic knobs for the same basic 303-like control: tune, filter cutoff, resonance, envmod, accent and decay. Unlike the 303 however, the oscillator can be varied from sawtooth to square from a knob on the front! Also featured is an external audio input to the filter for processing other elements.

The FB-383 makes a decent 303 sound however it lacks too many functions that should be there. Controls do no send or receive MIDI and there is no memory for storage of your own sounds. However, at its low price tag, you get what you pay for and for a quick and easy 303 the FreeBass comes in handy!

I used to have original tb303 but one day it just stoped working. I came across to modified freebass fb383 and have to say it sounds even better then original. Drive and resonance boost modification brings the synth to another level. It gives the bite to the sound. You can even process external audio thru the filter. Amazing, highly recomend to buy one

Simple but surprisingly good fat sounding synth. Excellent for industrial bass sound. Very underrated

Hi guys. Does anyone know where i find the manual for this synth? I'm pretty new to all this and can't seem to get a sound out of it.

i had one of these back in the 90's and my enthusiasm for it just grew and grew. Ok so no midi control but boy, can it make a noise! From mellow to miaow in one (or two) moves of the wrist. I actually bought another one cos I liked it so much but the 2nd one never sounded quite the same. Shame.
