Don't you hate it when your headphone crossfader goes kaput when just when you have finally mastered that scratch in your headphones? Try learning it on the regular crossfader before the gig next time, dumby. Replacement HEADPHONES Crossfader for Vestax mixers. This is a part that REQUIRES SOLDERING and the skill of someone-experienced with a soldering gun. This is not a "user replaceable part"; it does-not simply plug in. Please do not purchase this item unless you understand these things, because we do not take returns on faders! !
