Sometimes a weak battery can produce odd results.
Make sure you have a good/ new battery.
When does the 'plop' sound occur?
Is it under repeatable conditions or random?

My Rogue makes a loud click when engaging the treble boost switch. Mica showed a solution to this specific issue in another thread, but it doesn't looks to be the same problem described here.

Because it's random, first try cleaning the filter pot by rotating back and forth many time, perhaps as many as 50. Make sure to get to the stop at each end.

Was the bass stored for a length of time or the filter pot not used in a while?

If you need to order the pot, send me an email and I will help you with the details. But try to clean by rotating first, because you might not need to do anything else.

Do try Mica's suggestion of rotating the pot back and forth through it's complete length of travel 50 times. This tends to solve lots of problems.

What do you mean when you say that the filter pot hangs down to the circuit board? Is the filter securely fastened to the body? The filter must be tight against the shielding on the inside of the control cavity so that it has a good connection to ground.
