No I never had a short scale 6071 single cut "Tennesean" bass... I had a '63 first year 6070 with the treetrunk neck, mute, etc. The sound wasn't totally vintage... it had a blade supertron style pickup as did the 6071... sort of electronic sounding, forceful, with pretty good output. But when U put the mute up it went totally thumpy upright sound.
According to Gruhn, the 2 p/u versions didnt' happen until 1968, suggestion that was a Baldwin idea.
Man it was killer but I needed the bread for the astro jet project... now that it is done, it goes on the block to pay for the Vette project, which is also done. those projects turned out great but cost a bundle.
