It's worth a shot placing the piezo on the front, although the potential problem is delay (not to mention phase issues): it'll take more time for the trigger to um, well, trigger.... Also the trigger waveform is likely to be more rounded with a slow attack, far from the ideal 'spike' you'd desire for good triggering... The potentiometer idea seems do-able, but will obviously require soldering. ### A similar mechanical approach is to tape a layer of open cell foam (or the like) between the piezo and the drum to reduce some of the signal strength. Aside from reducing signal strength, the foam also help keep the trigger signals clean by reducing the noise factor (part of the reason why Roland uses those blue closed-cell foam cones: cleaner triggering). Obviously I don't know the particulars of your set-up, but needing to reduce the vibration going into the piezo is generally a preferable problem to have than trying to increase it: the latter is harder to deal with...
