I bought KevinLanes Lakland JO5 about a month ago (the one with the Sadowsky onboard pre installed) and overall Im quite happy with it. However, I think there may be a problem with the push/pull VTC potentiometer on the pre amp. I was playing the other day with the highs rolled off a bit and I noticed a significant increase in EQ/volume like someone had turned the pot back up. I thought I inadvertently hit the pot while playing but a few seconds later it came back down. While turning the pot theres a lot of noise and intermittent contact with the tone coming in and out. A few times I turned the VTC all the way down (counter clockwise) and all the highs were still there. Then when I jiggled the pot, the highs cut out. I tried cleaning the pot with some contact cleaner but nothing. I think the pot may be defective. Another question: With the VTC in passive mode (pot pulled out), Im not getting any tone control on the stacked bass/treble. Is this correct? Im trying to determine if there are more problems than just the VTC pot. Any of you Sadowsky owners have a spare vtc pot laying around? Otherwise, I guess Ill see if the guys at the shop can sell me one stand alone.
