It’s been a busy 2 weeks. We’ve been working hard to finish a small run of 10Echo Benders. This is a casper designed, tweaked out studio/stage echo with some added zazz. We’ve also been working on a few one off pieces like the Speak&Spell/Read pictured above. These pieces will all be available for purchase within the week.
on sale soon!

Speak&Spell LFO sound sample
Thursday, November 29th, 2007 | Posted in casperstuff
A sample of the S&S LFO in action can be heard at the bottom of the Speak&Spell Bending page. It’s actually a Speak&Math in the sample. I start the S&M with the LFO on and then activate the “HOLD” mod which stays on through the whole sample.
Speak&Spell LFO
Wednesday, November 28th, 2007 | Posted in casperstuff

Here are schematics for adding a pitch modulating LFO to your Speak&Spell.
I also added some simple mods that work well with the LFO. One is a “HOLD” effect which grabs the sound that is playing when it is activated and loops it. The other is a “TONE” effect which generates a straight tone.
This is a pretty rough design and I’m sure it could be cleaned up and improved, but it’s simple and it does work pretty well.

too much to write about right now. Lots of new pieces. working on schematics, sound samples and general documentation.
Played a show at the Piksel Festival in Norway. See the performance here:

scroll to the right until you find “TheBunker, Piksel.no Casperelectronics”
The drum beats are made using the sequencer and drum box (the brown and white one) shown in the picture above. The gray box above is a dual voltage controlled filter that I built at Piksel.
BOSS DS-1 mod
Monday, October 22nd, 2007 | Posted in casperstuff
I experimented with a BOSS DS-1 pedal yesterday and found some really fantastic mods.
My friend brought the pedal over and showed me some mods he had found that were cool sounding feedback loops. Basically this is where the audio signal from somewhere along the signal path is fed back into an amplifier stage somewhere EARLIER in the path. This creates a feedback tone and can result in some really nice sounding, rich tones when an incoming signal fights with the feedback tone. The problem is that when there is NO incoming audio signal, there is just steady, squealing feedback.
I wanted to find a way to make the effect happen only when there was sound feeding into the pedal, so that when you aren’t playing into it, there’s no sound output.
I had a suspicion that a transistor used as a gate was the answer. I experimented with some transistors configured different ways and found the 2N3904 NPN to be the most useful. I encourage people to experiment with different types though.The best effect we found is drawn below. If you have this pedal, you really have to try this! 
It’s a really great sounding effect. Sort of ringmod meets harmonic exciter of some sort. The “distortion” knob controls the effect.
I soldered the transistor to the component side of the board so that I could still close the back cover. The back cover presses right against the solder side of the board so there’s no room to add components.
