Hello Folks, what were the ohms on the volume and tone controls of the MSA Classic's before everyone started removing them?

Hello Mike thanks for the response, what ohms were the pots do you happen to know what they used? was it 250k or 50k?

According to Jim's post, he had some original pots from MSA in his shop, and they were 1 megohm linear taper (B1M) for tone, and 1 megohm audio taper (A1M) for volume.

I owned a MSA that someone had removed the tone and volume controls. Those knobs protect that little 3 way switch that controls the necks. Broke 2 switches putting the guitar in and out of case. Added a bar of wood and bolts through volume and tone control holes.

I had a MSA S10 Classic with the volume and tone control. I could not get stage volume from the guitar. I gator clipped direct from pickup, Had great volume.
I put a 2 way switch under the guitar, Wired one leg direct, The other leg through volume and tone control. Worked great, And kept the guitar looking original, Amp. volume control set stage volume.
