Hi all.
 
SlotH,
The bitumen tape do all the muffling. The place mat is just a way to hide the bitumen tape (and if you don’t like the ‘green effect’ on the back of your cymbal, you can use an antique gold spray paint on this place mat).
Your cymbal will work fine without the optional place mat.
The design is very quiet (quieter than muffling a cymbal with your hand or even a pillow).
 
BGibson72,
Let’s check that on your dual ride cymbal 🙂
 
.Put some bitumen tape everywhere under cymbal but not under the bell.
 
.Wiring :
Bow piezo -> Jack sleeve+tip
(The bow piezo must not be placed next to the edge, but next to the bell – Take a look at one of the pictures joined to the first post of this thread)
Bell piezo -> Keith Raper’s PP to PS circuit -> Jack sleeve+ring
 
Hope this helps,
Best.
