Yamaha DTXpress/DTXplorer/DTXtreme

Aeron,

I am having exact same trouble with the TP120S snare on my DTXtreme, 
and it only happens when the bass guitar amp is either too loud and 
boomy, or too close to my kit.  At the last gig, I asked our bass 
player to move his gear off my part of the stage floor and had no 
problem.  Reducing the Gain, which makes the snare pad less 
sensitive, was also helpful to some extent.  However, in the event 
that our bass player is unwilling or unable to comply, I always pack 
my acoustic snare as a standby!

Nick
