Tea Kick is a universal analog circuit which is based on improved version of the twin T resonant structure, and mainly inspired by analog drum designs of Standa Filip. The basic principle or this drum is to create a virtual electronic membrane which you strike with electricity, the membrane vibrates and creates a very natural drum wave which, when outputted to a speaker (another membrane) sounds very authentic. To adjust the membrane, we have the TUNE and RESONANCE control. Think of using those as if tuning an acoustic drum. There is a CV input for tuning the circuit so it can change character from a bass drum through all the toms to woodblock. There is main TUNE control knob for the tuning and also a CV Input with ATTENUATOR.

There is a RESONANCE control which affects how resonant the circuit is. However, the resonance also affects the tuning: the more resonance, the lower the drum sound is. Add resonance to get longer decay drum sounds. The resonance range switch can limit resonance from self oscillating. When you switch it up, the resonance control makes the circuit self oscillate, so that it can be used as a kind of VCO.

Tea Kick also has a click generator with tone control which is mixed into the signal. Think of the click as of a stick which you can use to strike an acoustic membrane of a drum – the resulting sound has different character. The click tone control also affects the spectrum of the twin T circuit. There is also SQUARE output and WTF input available for more fun experiments..

Before starting this kit, prepare the following tools: soldering iron (15-20W will do), multi-meter, protective eyewear, flush cutters, no.2 hex screwdriver or allen key, phillips screwdriver, and some coffee. Go through the build guide under the links section below, and make sure that you understand all the steps.

We suggest that you work in a clean and well-lit environment to avoid accidents or losing any of the small components.

IMPORTANT!

If you have never soldered before, check out this great tutorial first.
