Hey everyone, got a slight problem with my euph! Since i bought it last year, (second hand) its always had clunky valves! Ive cleaned them out, got new felts, and tried just about every trick in the book but cannot seem to get my valves silent. Its realyl starting to annoy me, especially when ive got solos and all you can hear is *clunk clunk clunk* It distracts people from the actual sound im making! does anyone have any idea how to silence my god awful valves?! Would be very much appreciated!
