FAT Freebass FB383 analogue synth tutorial, review, sound demos: is this a good Roland TB-303 clone?
video upload by ako
"I've been really liking the FAT Freebass FB383 analogue TB303 clone again (even if staying in tune is more of an aspiration than guarantee with this thing). It’s fully analogue and the filter does all the good self oscillating squelchy things you want from a 303 even if it does lack a sequencer (slides and accents can be triggered with MIDI). Some sources claim it's a fairly faithful clone of a TB-303, not sure how valid that is though. For those outside the UK wondering, this synth is just a MAM MB33 with a different paint job. You can also feed audio into this synth and use it as a MIDI triggered enveloped / gated filter, which is kinda cool! Had this set up recently for some acid parts (ofc) and it’s been fun using this synth again so I thought I'd make a video on it - hope you enjoy :)
Chapters:
00:00 - review, background info and basic features (incl. how it differs from a "real" 303 and other clones)
07:58 - Programming sounds (pt1. VCO and tuning)
10:20 - Programming sounds (pt2. filter and envelope)
12:24 - Programming sounds (pt3. Accent and slide)
15:47 - Programming sounds (pt4. Using the filter's external audio input)
21:07 - Sound demo 1 - the synth in a track with no effects on it
23:02 - Sound demo 2 - the synth used in a track through an overdrive pedal
Sound demo 2 is a verison of my 'MYST.wave II Unfinale':

"great fully analogue vocoder, made in Germany, by FAT. which is the same as more famous company MAM, and this unit is completely identical to legendary MAM VF-1. back in the time they were releasing their products under a few brand names, with different panel designs, but electronically identical.
fully analogue, can be used traditionally, but also as a very experimental tool. any signals can be plugged in and mutually processed.
this unit has an amazing modification installed - tumbler power switch on the back!!! which makes things way more convenient. originally they don’t have power switches, and you had to plug it out manually every time."

"monophonic analog clone of the TB-303. The FAT Freebass FB 383 was made under licence by MAM and is a version of the MB 33 with a special front-panel design as part of an exclusive deal with Turnkey music shop UK - which is where I bought it originally.
The FAT Freebass FB383 offers all the same basic sounds and controls as the original TB-303 in a 1-unit rack module. There are 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 controlled from sawtooth to square from one of the knobs on the front.
There is also an external audio input to the filter for processing other sources and a dipbutton control to select the MIDI channel.
On the front there is a power on LED, a MIDI activity LED and an auto tune button."

"Mint condition FAT Freebass FB 383 MAM Mono Synth Roland Tb-303 Clone
This has a pure Analog signal path and has that original drippy 303 tone. It’s wonder from new and in superb condition / not much to say really it does what is says on the tin....
I’ve used it for lead sounds as well as 303 - it’s actually a good lead synth as well.

"Freeform Analogue Technologies Freebass FB383 - Basically a rebranded version of the Music And More (MAM) MB33, which is basically a Roland TB-303 clone. It's a pure analog synthesizer with a real VCO and a rich squelchy highly resonant filter. The famous 303 glide/slide is controlled by playing legato (or increasing the gate time on an arpeggiator.) I believe these were made in Germany in the mid 90's."

"Famous German made TB303 clone sold under different names:
MAM MB33
Freebass FB-383
This is the Orange and silver version, I also have the older black version for sale. Perfect condition.
The MB 33 is a rack-mounted TB-303 clone released in the mid-nineties by German synth maker MAM (Music And More). It's basically identical to the Freebass 383 (which had a different front-panel design). It is a true analog monophonic bass synthesizer with MIDI implementation so you can create 303-like bass lines from your sequencer. Its single VCO offers the same two basic waveforms as the TB-303: a sawtooth and square wave. But in the MB 33 they can be mixed together for a more interesting tone than the 303 could originally produce.
Additional knobs control the VCO tuning, filter frequency cutoff, resonance, envelope mod amount, envelope decay time and accent intensity - the same controls found on the TB-303! The 24dB lowpass filter can also produce the characteristic sound of the 18 dB filter used in the original 303. There's also an auto-slide function (4 octave range) for producing those 303-style slides and a separate input for filtering external signals through it. Unfortunately there is no program storage."
