This is Jolana Basora bass with its' sister - Jolana Diskant guitar. Normaly the Basora should been in the same colours as the Diskant; this one has been stripped to the naked wood (just triplex!) and varnished (although well done!).
Note the Basora's very special chromed scratchplate, not downwards but upwards the body! Unfortunaly the pu-covers are gone, but must be the same as on the Diskant, StarV etc...
