Delptronics LDB-2e “Little Drummer Boy” Analog Drums Eurorack Module

Delptronics has released the LDB-2e “Little Drummer Boy” analog drums Eurorack module, which packs eight drum voices into a 6HP wide module. 

The LDB-2e is an update to their LDB-1e module. It is 2HP wider and now includes the individual volume controls and output jacks of the old 6HP expansion module. The sounds are new, too.

The LDB-2x expansion module is new and gives you knob and CV control of the pitch of every drum, and the decay of the kick and open hi-hat.

  1. Great little Eurorack unit, but everything Euro is starting to look very expensive lately compared to the DrumBrute or DM12 etc. Particularly expensive if you are paying in GBP now-a-days- I have 3 case full of Euro, love it, but the new wave of highly affordable analogue hardware is taking my budget in a different direction.

  2. looks too frickelig – there is not much comfortable space for my fat fingers to play around … but the sounds and the possibilities seem right …
