Analog Hand Clap Stompbox / Module

The Delptronics Thunderclap is a classic analog hand clap effect based on the famous hand clap sound of the TR-808 and TR-909 drum machines. Our version has extra knobs to tweak the sound from claps to finger snaps to snares to cymbals to thunderous crashes.


The Thunderclap has four knobs: noise level, filter, decay and volume. The knobs can be adjusted to create hundreds of unique percussion sounds. Turn the noise level, filter and decay knobs to approximately 11 o'clock for the classic hand clap. Turn them all the way up for an effect that sounds like dropping a metal trash off the roof!

The Thunderclap can be manually triggered by pressing stomp/trigger button, or externally triggered by any positive pulse from a synthesizer, sequencer, or drum machine. It makes a great accompaniment to a TR-606 or Delptronics LDB-1se.

It also also has a built-in mini-sequencer. Hold down the record button to record a sequence of trigger events (button or external) and the pauses between them (e.g. "clap - - - clap - clap"). Then, whenever it is triggered, it will play back the recorded sequence instead of a single clap. To loop the sequence, hold down the trigger button, then press the record button. A trigger event will stop playback of the loop. Pressing and releasing the record button with no trigger events clears the recorded sequence. The sequence can be up to 32 steps long, and the pauses can total up to two minutes.

The Thunderclap Stompbox comes fully assembled and tested in a heavy-duty aluminum enclosure with awesome graphics (pictured below).
