Sweet: A Back To The Future Time Traveling DeLorean Inspired Bass Guitar

This is the Time Machine Bass crafted by father-and-son guitar making team Steve and Richard Doner of Doner Designs. The guitar was recently sold on eBay for $8,880, with all proceeds benefitting the Michael J. Fox Foundation for Parkinson’s Research. Some more info about the guitar while I precariously stand on the edge of the toilet to hang a clock hoping I slip, hit my head on the sink and invent the flux capacitor:

This one-of-a-kind custom creation results from a ~300 hour labor of love by Steve and Richard Doner. The bass is a fully functional instrument constructed from premium components, but is also a work of art suitable for display by anyone, musician or not.

Direct reference to the Back to the Future movie series was avoided, out of respect for intellectual property, but the bass features a selectable destination year display, a device resembling a flux capacitor and other electronic gadgetry sure to please fans of the time travel entertainment genre, 80’s pop culture and musicians alike.

Sweet. Of course the only thing that could make it even sweeter is if you played at 88BPM you actually time traveled. Think about it — one minute you’re jamming out at band practice, and the next you’re standing where band practice will take place 80-million years in the future, about to make love to a t-rex! “Wait, what?” Squirt some baby oil on this toilet seat, it isn’t slippery enough.
