The crackle guitar  project was born in July 2009 when I (musician, visual artist and performer Bertram Dhellemmes) visited musician, composer and sound devices builder Daniel Schorno in Amsterdam, and started to tell him about my new activities as a wannabe guitar maker.  We’ve been very quick to consider the potential of a convergence of our domains into a common project, that would be to create an hybrid instrument  merging electric guitar and crackle box. Daniel and I worked together already on a couple of projects with dancer Frank van de Ven, mostly on the complex and long running OUDAPO project exploring the constraints creative technics applied to improvisation in dance, music and scenography.
For a few months we exchanged ideas, notes and sketches, until Daniel could respond to my invitation to come and work at the Akademie Schloss Solitude in Stuttgart where I’m currently resident artist.  We tried to consider all the possibilities and the needs we would have to gather a maximum of material and work intensively for 3 days with everything at hand. The biggest issue was to isolate each guitar string to integrate them in the crackle circuit, while keeping the acoustic qualities of the guitar – that was solve with the discovery of teflon bridge saddles to put in tune-o-matic style bridges, each string ending in individual ferrules connected to the crackle circuit (see pictures).
We started to work from two identical models of Japanese 70s cheap guitars (we wouldn’t want to destroy better guitars), Daniel and I having each a slightly different project with different options. The biggest difference is that my guitar has the possibility to be used with it original clear sound, a sound filtered buy the crackle circuit, or the pure crackle sound, that can be mixed at different levels, when Daniel’s is more focused of the crackle sounds. I will also extend the circuit on the whole guitar body. Daniel’s guitar will have an extra embedded speaker and a controlled stroboscopic LED interfering with the crackle circuit. I will also retrofit the guitar with a new finish.
We should meet again next February in Amsterdam to achieve the project and present the guitars to the enthusiastic crowds!
