Deltalab Effectron JR. Actually the same as Effectron 1024 (i checked, it’s the same pcb) I like the bit crushed sound of that thing. Came with defective potentiometers.
Also got an Effectron II, that one featured some bad RAM.
These units are interesting as they are using DeltaTau A-D conversion which reminds a bit of the nowadays very high-end 1Bit converters. These here of course running at a much lower frequency. No good schematics for these available, had to dig around at patentsonline to find some description of the converter theory.
Apparently King Tubby had a couple of these in his racks…
