The TD404 offers a broader range of exploration for music, engineering, and production enthusiasts, alike. Its simplicity invites users of all skill level to engage in a sonic adventure beyond the realm of any instrument conceived before.
The core of this project involves three key components: a contact/piezo microphone, a Velleman K1803 Preamp, and a Synthrotek PT2399 Delay. They are chained in said order to mono output. The intent stems from music producer/engineer legends such as King Tubby and Scientist. First, the various parts (e.g. strings, springs, and in between) offer textural tones which are picked up by the contact mic and amplified by the preamp. While stimulating, this is taken further by the delay system which features feedback, mix, and repeat rate control. Stemming from influences of dub and techno, one may expand the reach of the system by repeating sounds and maxing the feedback to obtain extraordinary results from otherwise ordinary components.
In all, this was a 60 dollar build. Considering it's huge return (aka bang for its buck), I plan to add a low pass filter and CV control on future iterations.
