My 1969 vox V846 wha changed where it was less trebbly like the gear on the pot was truned over night just sitting. I was able to set it back to the sweep it had by ajusting the pot gear and arm two teeth. Is this possible to happen or am i tripping some how thks

Is the pot dirty?
Assuming regular contact cleaner would work but on a vintage piece like that I'd check these days.
Had a 846 with the vinyl bag for ages until I sold it to a Hendrix fanatic.

Can still get dirty, even a minute after you install it.
That and battery change would be my go-tos.

Maybe something obstructing the pedal sweep at the hinge or the switch contact point or something, causing it to travel a little less, made it lose a bit of the treble end of the sweep.

Two things: 1. Make sure there's a toothed lock washer between the pot and the mounting lug, and be sure the nut on the opposite side is snugged down. If there's no lock washer between the pot and the lug, the pot can slip in place. 2. Ensure there's no play or slop in the pressure pad that presses on the rack to keep it in full contact with the pinion gear on the pot shaft. The pressure pad is usually a Nylon cable clamp (they're perfect for this job). If there's grease on the gear teeth, wipe all that stuff off. There's no need to use grease, but if you like you can apply a small dab on the pressure pad where it rubs on the back of the rack (the smooth side of the rack). Look:  The reason you don't grease the gear teeth is because wah pedals live on the floor where there's dirt, dust, Ed Asner's back hair, and who knows what else kicking around down there. All this stuff sticks to the grease and it turns to mung that jams up the works. The gears are Nylon and need no lubrication. Some makers grease the gears, and that is a huge mistake.  |

Thanks for the reply but the bottom picture that is whats wrong is wrong about the lock washer placement. I have been a mechanic for decades and used thousands of lock warshers and it goes against the nut to keep it from losening. if its not against the nut i can losen and will. Then the pot will turn |

If you look at the top pic, there's a lock washer under the nut as well as the pot.
It's similar for controls on a guitar: look at just about any guitar and you'll see there's an internal-tooth lock washer under the pot inside the guitar, and a plain flat washer under the nut on the outside of the guitar. Output jacks are the same way.
The reason for this appears counterituitive (from a mechanic's perspective), but in use, torque is applied to the pot via the shaft and the lock washer holds the pot securely and prevents it from rotating.
Some applications use a pot that has a tab or pin that engages the panel where it's mounted--which does the same thing.

The nut being secure will keep the pot from moving in this use as there is really no tension or torq created in a wha. I have been using and repairing my wha's for decades and never had a pot come lose from lock warshering the nut |

Into horn players and copping their licks.
Horn Mutes!
Trying to find something for the guitar that will give me the same feel and expression of a trumpeter using a horn mute.
I'm thinking maybe Wah pedal.. so I go out on the internet and low and behold, I find out when Vox first invented the Wah pedal (taken from the Vox Super Beetle tone controls)... Execs thought the wah pedal would be best used for Horn players (How they would use a wah pedal IDK... lol)
anyway....
Is there a wah peddle that is smooth, Think.... Intro to "If I were a bell" from Relaxing with Miles Davis.. not trying to nail the horn sound exactly ... just the expression and vibe
Any suggestion?

my wha is still doing it. I put glue on the gear to make sure it was not slipping and also tried to turn the gear on the shaft. It must be something slipping in the inside. its always goes darker (less treble) and i have to move the ajustment one tooth. is it possible to slip on the inside. The pot is secure and cant move the ground wire is a solid tight wire giving aditional force from slipping thks
