The bass is now done , and varnished. When the varnish is totally hard it'll get its final touch up and polish. Its such a pity that the instrument had its original varnish removed!
The real experiment was to replace the very large linings with smaller than conventional ones in the hope that the bass would simply sound better.
I also did thin out the bass bar and am happy to report that the alterations have made a big difference to the sound , especially the attack which is now fast . The bass has retained its original 'darkish' sound but is now more responsive and I think a little brighter sounding than before
