Hello.

This is my first post.
I have a Marshall G30RCD practice combo that has been sitting around for awhile. I got it for the kids years ago. Dusted off it looks brand new, very clean inside and out. When turned on it plays, on both clean and overdrive, but no ability to change volume, tone or gain. So, in opening it up I discovered that 5 of the control pots were broken off at the base.


The pots broken are CLEAN CHANNEL - Volume, Bass, Treble. OVERDRIVE CHANNEL - Gain, Bass.
The rest of the pots (OVERDRIVE CHANNEL - Contour, Treble, volume, & MASTER - reverb) look fine.

So, the broken pots will get replaced. I expect that will fix the problem.


My question is, should I replace ALL of them?
I suspect the amp was either dropped or pushed over which resulted in cracking the 1st 5 pots.
Is age a problem with these cheap little pots?


Any advice is appreciated.
