I know of 2 Avalon users that preferred it with a headstock: Andreas Vollenweider and Sigi Schwab
Rolf followed the wishes of both great musicians and friends.
I suspect this guitar here was a prototype for this purpose. its a standard Avalon and Rolf Spuler added a headstock.
without tuning block its more hollow and sounds rather like the new series
and we got space to add a Polybass board, but where would the controls be?
you, the customer, can choose which Paradis electronics will be mounted:
the original preamp that connects with a Polysubbass or Polybass-Box
a Polybass board, with controls on the back, on the body or even on the ground (stereo jack)?
