Bothners are the distributors, so you should find or be able to get from Jean Village Music.

I have to say though - the new Boss volume pedals are great - nearly as solid as the Ernie Ball and much cheaper.

Which boss ones alan? I used to have one, found my old one to be either too "tight" and too "loose", so i couldn't control it acurately enough

The FV-500H and FV500L (high and low impedance respectively). The pedal torque is adjustable, so you set it to however stiff or loose you want. I also like that you can set the minimum volume, which makes it great to change to a preset rhythm volume.

I've got the Low impedance model, which is also stereo so I can set the volume of the piezos and magnetics at the same time:
