It looks like Din Sync is coming out with a new DIY "replica" clone of the TB-303. There have been plenty of emulations of the 303, but only a handful of actual clones. There was the x0xb0x was based on the schematics of the original 303, Cyclone Analogic's TT-303, and most recently Abstrakt Instruments Avalon Bassline Synthesizer which I've been told has circuit boards that can be swapped into an original TB-303.

"Ok ill start with a few obvious questions, feel free to ask more and I'll try to answer them for you.

Q: What is the RE-303?
A: the RE-303 is a replica of the Roland TB-303 motherboard and switchboard

Q: Why do we need yet another 303 knockoff?
A: There have been many clones, I honestly wanted to make a genuine replica. Now the dead TB-303's with broken motherboards can come back to life and new TB-303s can be born.

Q: Hasn't this been done already?
A: Actually no, not in the purest form. We've had the x0xb0x which sounded very close but didn't look the part. We've had the TT-303 which looks that part but is not a genuine replica of the original hardware. The RE-303 circuit boards have been made by dissecting a mint condition pristine TB-303 and manually recreating the board in CAD from the hardware rather than the service schematics. Every nuance and mistake in the hardware not in the service notes is recreated in the RE-303. It really is for all intents and purposes a TB-303. [Note: I was told the Abstrakt Instruments Avalon Bassline Synthesizer boards can be swapped]

Q: When can I get one?
A: As soon as they are ready, just post on the waiting list thread. By the nature of this project It's likely to be limited, so first come first served.

Q: What about kits?
A: This is likely to never happen sorry, this project is probably going to be the most hardcore DIY many have tried. But it will be worth the effort!

Q: What about rare parts, the VCA and CPU, memory chips, switches pots etc etc.
A: There currently exists many solutions for these today and I'm actively working on some as part of the project.

Q: How long will this all take?
A: How long is a piece of string?"


  1. The title is a bit misleading, he's not reproducing the 303, just both PCBs. This will be a DIY kit the likes of an x0xb0x.
