You could use a spring loaded pot - the vtg of this pot could simply be 
added to the keybd o/p by use of an op amp.. - if you're in log land [v/oct] 
then applying 2 v across the pot will give a +/- 1 oct range [or 1/6 V on 
the pot would give a +/- 1 tone range etc] you can still get the spring pot 
assy used in the SH101 I believe [I managed to get one last yr for a repair] 
- I'd reckon finding a pot assy and building the ccts yourself would be the 
cheapest option.
Cheers,
Dan



As well, are there any particular old bend boxes to avoid,
