From Thomas Henry:

I've been designing electronic bass drums for some two dozen years now, but the Bass++ is by far the best, if I may be so immodest. It uses no hard-to-find parts, is very stable and predictable and is a snap to build, weighing in at two chips only. And since it employs legitimate analog synthesizer technology and not the old ringing filter routine, it is very quiet. Before continuing, let me hasten to add that the Bass++ is great for bass drums (of course), but also is perfect for tom-toms, woodblocks and related instruments thanks to its wide range.

From Timo Rozendal:

Changes from original design: 
- sensitivity pot is moved to back of module 
- provided panel pcb, so no wiring required 

-impact is a clicky impulse 
-shell is a triangle-like tone 

The panel icons might need some explanation, or just some wiggling hihi , I will make an explaining picture later. 
but if these are the pots: 
1 2 
3 4 
5 6 
7 8 

then they are mapped to: 
1. impact level 
2. impact tone (left is muffled, right is bright) 
3. shell level 
4. shell decay length (mapped to amplitude) 
5. shell tone 
6. shell sweep (amount to which the decay influences the tone) 
7. shell cv (amount to which the cv input influences the tone) 
8. total level

well laid out PCB with affordable parts.Review by isohedra
Great pcb / panel set. nothing super expensive in terms of parts used, and a relatively easy build.

the sound output on these seems a bit low, and the panel silk screen on some of these
is definitely clearer than others.
but it puts out some nice sounds and you can bump up the volume with something else.

great affordable drum module! (Posted on 8/13/2016)
Easy Build, Good Electro KickReview by Useful Noise
A very nice build like all of Timo's projects. It's a mini-MPS type clicky electro kick. (Posted on 5/22/2016)
