FutureRetro opens FR-777 pre-orders, limited-run acid bass synth returns in 2026

FutureRetro has moved the FR-777 from teaser territory into the real market, opening pre-orders at $1,299.99 with direct availability slated for summer 2026. For acid heads and vintage collectors, that turns a long-rumored return into a concrete buying decision: a limited-run, production-ready revival of one of the most recognizable bass synths in the 303 lineage.

The reason the FR-777 matters goes back to the original 777, released in 1997. FutureRetro says that machine was the first 303 clone to add the all-important sequencer and real-time pattern editing during playback, which is exactly why it earned cult status beyond simple clone duty. The new run keeps the core analog formula intact with two VCOs, a sub-oscillator, saw, square and PWM waveforms, two ADSR envelopes, a syncable LFO, and a resonant 24 dB low-pass ladder filter. In other words, this is not a nostalgia shell with a trendy badge; it is still built to do the acid thing from the ground up.

What has changed is the workflow and the scope. The FR-777 sequencer now offers 16 banks of 16 patterns of 16 steps, plus ratcheting, note probability, randomization, data shuffle, MIDI note input, MIDI Thru, and filter-cutoff CV input. FutureRetro has also added broad filter and pitch modulation, selectable 3-pole and 7-pole cutoff modes, filter gain, and overdrive, all under a new 2.4-inch OLED and encoder-based control layout. That is a serious expansion over a simple reissue, and it gives the box enough modern sequencing muscle to stand up to contemporary hardware rigs without losing the hands-on appeal that made the 777 name matter in the first place.

The physical redesign points in the same direction. FutureRetro has put the instrument in a slightly larger case, switched to 1/8-inch CV jacks for easier Eurorack integration, and moved the analog control board to a hybrid SMD and through-hole design. The audio output still sits on a 1/4-inch jack at the back, and the unit keeps the usual MIDI I/O, CV I/O, gate I/O, pitch I/O, accent I/O, filter input, and audio input that players expect from a serious bass machine. FutureRetro’s Japanese shop page says the limited edition exists thanks to its Kickstarter backers, while the dealer inquiry page shows the company is actively taking wholesale orders again.

The practical verdict is simple: this looks like a credible modern substitute for chasing a scarce vintage 777, especially if the goal is a live, pattern-driven acid box rather than a museum piece. The hardware lineage is intact, the sequencer is more capable than the original, and the summer 2026 ship window gives collectors and working musicians a real target instead of another lost relic.
