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!

It's fat! It's monophonic! It sounds like a barking dog or a myaoing cat! I really love it :)

It's a 303 clone, but it does not really sound exactly like 303, but for me it doesn't matter at all! I've had it for several years now and it's for keep :)

I found one of these in a rubbish skip on an industrial estate. I wasnt quite sure what to expect from it but i took it home bought a power supply for it and my god i will never part with this. Sometimes though if i send to much midi notes to it it will stop responding and i have to power off then back on. other than that i have been having lots of quality basslines booming out. I cannot believe how easy this is to program and get good sounds out of. I can program for hours a digital synth and still never get as good bass as this. Go buy one they go cheap on ebay.

Well.... this synth isn't great tb303 clone comparing to x0xb0x or acidlabe bassline, but it can do amazing things with only few wires and switches.
here is an example of bass boost and extended resonance. I have few mods to come ;)

Try pressing the "Retune" button with an external noise source going through the external input. 9/10 times it won't do anything, but sometimes it gives really weird and quite insane tuning options!
