VS-100 Playback knob malfunction - a common error

Hi all,
 
Just thought i would bring to your attention that both mine, and 2 other friends v-studios have all suffered the exact same problem at the exact same time, around 1 year after purchasing these systems new.
 
The main playback level knob has broken to the point that no proper and constant level can be set, and it has lost its -10>0>10 bearings. Sometimes the level is at zero, and sometimes with the knob in the same position it could be full volume. It also seems to change levels by itself very easily during use due to the malfunctioned level knob.
 
My band uses our unit as a backing track player so this is a showstopper for us until we can repair it.
 
I would think its just a hardware malfunction in the pot after a fair bit of use, but it seems strange that 3 different units all had the same problem at the same time.
 
so basically just be aware that anyone with a v-studio is likely to have the level knobs on their units start to malfunction (if they have used it a fair bit), as it seems they dont have a very long lifespan.
 
its not a hugely expensive exercise to replace the part, but getting into the unit and replacing circuit board components is never a quick and simple job.

I agree with kc2ine. I have many guitar amps that go through this same type of problem if not regularly cleaned.
However - 1 year does seem rather quick.
 
The other possibility (and yes, it would likely require a repair shop) is that there was a bad solder pt, or bad potentiometer placed in the unit. Because of the way things are built these days (automated), that could result in the same problem - over many machines, explaining why you have seen more than one VS-100 with this problem.

If we have units from the same batch maybe we will see this problem as well - or we may never see this problem.
Thanks for the heads up on this.

  The fact that cataclysm says his friends are having the same problem with the same pot in particular, doesn't suggest to me that dirt and dust is the cause.

they all could smoke same weed...

Hey;
I'm finding not only the playback (volume) knob accuracy (@the low end) intermittent; but the fader in manual mode does not read/write data at the lowest end. Frustrating on a less-than a year old piece of equipment.
Zap!

again, faders especially are prone to catching dirt since they have open guts....
Do you clean your instrument? so your equipment requires some care as well.

I agree zap, unless you've been doing sheetrock rip-outs in your studio without protecting your gear or something like that (which I'm sure you're not), you should not be having dirty pot or fader issues at less than a year. like I said earlier, i have no issues like that at all and this VS100 will be 2 yrs old in December. A dirty pot will make static type noise also, that's the tell-tale sign.
