Stompbox dial not working on vypyr 75

Post by georgeyates » Mon Aug 12, 2019 5:18 am

I just bought a vypyr 75 and to my horror, the stompbox dial
Does not work , I have reset the amp tried turning them onoff
With the sanpera but nothing. Even the factory patches , eg twin plus tubescreamer
, it does not sound like the tube screamer is on.

When I turn the dial there is just a little break in soundbut then
Nothing. All parameters are up full also.

JUst got this yesterday and would love to get this sorted

Do the presets work when you first turn on the amp (before you touch any dials(or stump dial))? If so the pots may be dirty. You can try cleaning them. You can try QD electronic cleaner or gunk-out for this. lay the amp on it's back, remove the knobs and spray straight down the shaft, turn the shafts fully several times then try out the amp.
