Roland TB-303 DEVILFISH

auction details - not this is not mine.
"TB-303 DevilFish circuit bent by Robin Whittle. However, there is a problem on the tempo oscillator. Every functions/knobs/buttons/sequnecer are working fine, but the tempo oscillator is not functional after "power on" for 2 mins. Eevrything works fine at the beinging and the tempo speed start to drop slowly. It works really well and nothing goes wrong if I use my SH-101 CV/Gate to slave the TB-303, everything is working. Also I am able to sequnce too, so I am sure there is nothing wrong with the sequncer. I have wrote to Robin Whittle about this matter, he said most likely there is something wrong with the Tempo OSC. That's why you need to get it fix if you want to use the TB-303 internal sequncer. (You can use any music gear with CV Midi convertor to slave it if you don't want to fix the tempo oscilator) Just give you a rough idea how you fix it. I would like to fix it myself but the circuit bent is too complicate in there, I am not able to remove the mainboard and take a good look at the front side of the PCB. I think this is a little problem which can be easily fix by changing the capacitor C7 and C9. However, I can not gurantee anything. Sold as is. You can change the C7 and C9 if you can locate the exact soldering point without removing the mainboard."

  1. Just gotta say, using the term 'circuit bent' to describe what Robin Whittle does with the Devilfish seems a little demeaning.

    I have nothing against the term or the process of circuit bending, but intelligent modifications based on an understanding of the circuitry are generally a much more involved than just randomly shorting various circuit points and coming up with different sounds.

    Both are enjoyable and can really expand electronic music circuits, but modding deserves a bit of respect by not calling it 'bending.'

    Ok, off the soapbox...
