Hi,  Does any one have an expression box from an upright
Duo-Art pedal electric which they wish to sell?

I have a USA made Steck (somewhat rare here in the UK?) 1/2-Duo-Art
which I intend to convert into a full reproducing action.

Otherwise any drawings, etc., of the unit would be helpful.
Also wanted: a Duo Art test roll.

Regards
Andy Hood
