concentric pots

[crane]

Hi guys!
The thing is that I'm modding a Boss SD-1 for use with a bass guitar. It really needs a clean blend. I really don't want to put the extra pot on the side of the pedal. It looks nasty, is really unhandy and unproffesional. I think that dual pot is the way to do this (like Boss MT-2 or RC-2 has). The problem is that I cannot find a good source of these parts. I've found out that they are called concentric pots. Anyone knows a good place to get themn? Knobs are a problem as well. I can find only ones that are for a guitar/bass guitar.

Values are really limited when you find them. Guitar part sellers usually stock a few values and the knobs, and of course for all things stompbox, Small Bear carry a mini alpha 100kb concentric as well as appropriate knob.

Thank you for your answer.
SBE is not my first choice since I'm located in Europe. But this time it seems to be the only choice
