If you REALLY want to take that finish off, do what I did as a kid: go to the hardware store, get some paint remover, brush it on the body. A half-hour later, scrape it off with a paint scraper. I guarantee you this will do the job. A really messy job.
I have mixed feelings about the results. One, I stripped off the original cherry red translucent finish from my 1964 Gibson EB-3 doing this. Boy I wish I had that finish back!
On the other hand, the bare mahogany has taken on a hand-rubbed luster of its own and darkened naturally over the years. The neck is now glossy, smooth and feels really good. They talk about a nitrocellulose finish letting the body "breathe." Wow, this bass practically pants....Also, Gibson now makes this bass with a natural color mahogany body and semi-gloss finish...which is exactly the way my 45-year old stripped-down bass looks! Go figure. Good luck.
