Its not my amp so I have no idea whats on the back.  I'm just the tech doing the work.  :-)
Hopefully there is a hole already there.

LOL.  But you know...know 2 Dumble Drills were made the same.

How hard is drilling the hole in the case?  I just have a normal drill....

Thanks guys.  I'll see about finding a pot and getting my buddies amp setup.  Glad it sounds like a simple thing.

DOes anyone have any more recommendations of specific pots and where to get them?

THanks.  So at 25k...where is that on the gain scale?  I'm finding I like to run my SDO with more gain.  It never gets flabby on the bottom end or grainy..even at max gain. 

What kind of a pot is in there now?  I'm assuming I can just remove it and put the wire leads in place where it was soldered on. 

I've got a buddy who's got a an Overtone and we want to move his gain pot externally like my Quinn SDO.  Just curious if anyone has done this. If so, what parts are needed?

Its incredibly handy having that pot external.   (Although I actually think its MORE handy having the HRM controls external).

Thx
