I had one of these back in the 80s. Paid £25 for it back then, so 30 now is a steal. It was my second bass after my Höfner -- it was a good instrument, clear and bright sounding after the woofy Höf. The body of mine was ply.
After I bought my Wal (my third bass) I lent the Columbus to a supposed friend who proceeded to f*** off without trace, taking the bass with him. I hope the strings snapped and took the thieving bastid's fingertips off.
