Been a while since I added to, or even updated this site, even though I’m still working. I recently built two Midfi Random Number Generator clones, and circuit bent a VL-tone. Here’s some rough pics. Hope to get some more content, and maybe even some revamping of the site soon. Continue reading “Some New Builds”plumbers

The video above is of my most recent bent VSS-30 that uses a 12 point switch bay using 2 way center off switches. This is my documentation on bending a Yamaha VSS-30. This ultra sampling keyboard has some really awesome capabilities on it’s own. I got this info initially from one of the bending forums, but I don’t know who to credit, so thanks whoever you are! I know some folks haven’t bent their VSS yet due to fear of frying, so hopefully this guide will help you.
*Note*When I first did this bend, I avoided the 2 red dots (power and ground). I’ve since bent another VSS-30 and used these points with no ill effect. As always, bend at your own risk */note* The blue dots in 2 rows are the points of the sampling chip. The blue dots in a straight line going up and down is where the points connect to the big chip. There are 2 pins on the sampling chip that connect to each other (yellow line), so that gives you 15 points to bend. I chose to use 12 of those points for symmetry, and I chose to use an RCA style patchbay. I found that Tablebeast did a layout on one of these that I really liked, so I did this one the same way. You can see/hear his Here. I chose to solder to the points that were up and down in a straight line for ease of bundling.
Here’s the board wired up.
Here’s the area where I chose to put the RCA connectors. I checked, double checked my measurements. The pencil lines you see are where there’s a plastic support on the inside of the case.
Here’s the installed RCA jacks. Not absolutely perfect (need a drill press for that), but lookin’ pretty good IMHO.
Here’s the front side of the sample crusher for those that don’t have one already (keep an eye out cause if you don’t have one you’ll want one!). Continue reading “VSS-30 Tutorial”
After some major diggin’ for info I found that no one had a specific guide for bending a Yamaha PSS-270, so I decided to make one. Credit to Sean “audioid” (myspace.com/audioidbentaudio), and Paul from circuitbenders.co.uk for the info on this bend. This bend involves cutting data lines that go from the FM synth chip (YM2413) to the main chip (XC194A0). The pins on the FM chip that go to the main chip are pins 2, 3, 4, 5, 6, 7, 17, and 18. You cut the traces, and then solder wires on either side of the cut. Take the pair of wires from one cut, and solder them to a switch, and this will allow you to turn the flow of data on and off.source
Over the past few years I’ve built a wide variety of instruments. Some are toys/keyboards/whatever that I re-purposed through circuit bending and modification, some are oscillator based instruments that I built from scratch, and more and more I’ve been dabbling in make effects pedals. I’ve built more things then I could ever possibly list here, but I will try and cover some of the more interesting things. If you want a better idea of what all I’ve done you can got to my Soundclick page. I also have a Youtube Page where you can “see” my instruments in action. Continue reading “Instruments”blog post
Mutators are a series of effects pedals I’ve been working on for a little while. A Mutator is, at it’s core, the circuit from a toy voice changer used as an effects pedal. I’m not the first one to do this by a long shot, but I build them more like real guitar pedals, which I haven’t seen anyone else doing so far.detailed description
