[HAM] Smooth Drawbars and Percussion.

[Premecz Mátyás]

Hi!

I actually made the rachet-smooth conversion on a B2 organ by sacrificing three
complete drawbar sets from M and L organs. It's pretty straightforward
to do, and the result is quite reliable. It gives a much more
'open' sound, more pronounced click, more highs and unfortunately a
bit more crosstalk but that might be just a bad ground somewhere.

It's a time consuming job (plenty of disassebling time) but only
requires basic soldering skills to do.

You have to dumb everything out from the rachet drawbar system but the
plastic spacers and the top and bottom lids. The shorter bus lines can
be soldered together to make them long enough.

If you choose this way make sure to have LM drawbar sets with
precisely matching numbers on them (many types of the 0-8 level numbers
are around)
