Scratchy Pots/Faders I bought a mackie 1604 vlz pro second hand and all the faders and aux sends are really scratchy. I'm not sure how to go about cleaning them up because I've heard too many conflicting ideas about circuit cleaner and destroying the lubricant in the pots. Any ideas?

If all other functions work for those channels, the most likely problem is the fader itself. These can fail and operate more like switches rather than faders. Without witnessing the behavior, I can not state that for sure. While these mixers are not the hardest to work on, they are time consuming. The faders can be purchased from Mackie directly. If you need to have this repaired, any shop that repairs audio gear should be able to erpair this for you. Where are you located?

If the faders have become noisy, they may be changing due to poor contact. Try putting a small amount of CRC226 in the center of the slot of each fader and then move fader knob to top and bottom. CRC226 is available in the electrical department of Home Depot in a small can with spout... about $2.70
