Yamaha DTXpress/DTXplorer/DTXtreme

I found that the hi-hats tend to rub against the the stands shaft 
which prevent them from fully opening or closing at times. Yamaha 
actually made a very poor system for this hi-hat. The bracket that 
mounts to the bottom of the high hat with the wing nuts is very 
poorly designed and very cheaply made. The hih-hats are too heavy for 
the plastic-pot metal system and tend to not stay tight which causes 
even further rubbing against the hi-hat shaft. I have found a 
solution that seems to be working thus far...

Put a washer in between the two back pieces that act as a collar for 
the hi hat shaft then tighten the round grooved nut and the wing nut. 
This will allow more clearance for the hi-hat shaft to move freely up 
and down. 

Purchase a tube of lithium grease and grease the hi-hat shaft. Also 
grease inside the collar area, especially where the hi-hat shaft 
touches. 

The hi-hats will be slightly shakier, but not enough to really matter 
or enough to affect your playing. The response of the hi-hats are now 
much much better.

Yamaha should redesign the entier mounting bracket for this hi-hat so 
that these modifications are not neccessary. It amazes me that they 
didn't do it right to begin with. Gheeeeeeeze!

Happy drumming everyone!
