AnalogicBass Bot TT-303 Mk1 Analog Synthesizer

Imagine holding a faithful recreation of the Roland TB-303's squelchy soul in a sleek, modern package—the Bass Bot TT-303 Mk1 nails that iconic acid bassline vibe with all-analog warmth right from the start.

Its single VCO pumps out selectable sawtooth or square waves across a 20Hz-850Hz range, feeding into a resonant 24dB/octave lowpass diode ladder filter, complete with dedicated knobs for tuning, cutoff, resonance, envelope mod, decay, and accent. The enhanced 303-style sequencer shines with up to 64 steps per pattern, 432 user slots plus presets, arpeggiator, pattern mutation via seven algorithms, live transpose, rotation, swing/shuffle, and instaDJ generation for endless grooves—plus MIDI In/Out (with splitter), CV/Gate/Clock I/O, filter input, main 1/4" out, headphone jack, and battery or 9VDC power in a compact 310x130x35mm desktop chassis. Real-time hammer and mute add live punch, while auto-tune keeps it stable.

Players love its gritty, authentic tone and creative sequencing for instant acid lines, though some note the original pots could feel less premium before later revisions—still a groovebox gem for TB fans.
