Little Mark Tube 15th Anniversary Bass Head Amp Amplifier Needs Service

Little Mark Tube 15th Anniversary Bass Head Amp Amplifier. This is a Limited Edition model they put out in 2016 for their 15 year anniversary. There is a 500 watt and 800 watt version, this is the 500 watt. It originally listed for $1049.99. Everything works on this head, the issue is the pots are scratchy and they cause some issues unless you turn the knobs a lot to clear. If you leave the knobs in one place, not too much of an issue, but as soon as you need to make an adjustment it becomes a problem. I read some forums and this is an issue others have had. The pots are mini sealed pots, mounted right on the board so not easy to spray out like normal pots. Please do a little research on this before considering. I have an email into Mark Bass also for some advice on repairing, will post response here.

Need more info or pics, please feel free to message me.
