How much would you pay for a guitar pick from Neon Trees? How about one of Donny Osmond's socks? Or a lock of David Archuleta's hair?

If collecting Utah-based musical memorabilia is your hobby, you should know that a former member of Imagine Dragons is hawking his bass ... for a mere $50,000. 

"This is totally for real," says Lemke, who was one of the founding members of Imagine Dragons; he parted ways with the band in 2009. Lemke now works in taxes and accounting in Alpine, Utah.  

"I've had people say I'm crazy," he says. "But I think it's worth it because the band keeps getting bigger and bigger, and so I'm just waiting for the demand to increase ... I'm not cash-strapped or anything." 

Some might argue that this instrument is a state treasure, something that belongs in a museum. Then again, some might argue it belongs on the wall of a local Applebee's. Either way, Lemke is currently selling this modified Fender Squire bass on KSL with the hopes that some Imagine Dragons superfan comes along with a fat wallet. 

Lemke says he hasn't gotten any bites on the bass yet, but if he gets a decent offer, he'd be willing to lower the price. "I think it's valuable," he says. "It would be more worth it for me to have the 50 grand than to hold onto it." 

The bass is autographed by Lemke himself and has had a few upgrades, including "Bartollini pickups, Aguilar active preamp and a Gotoh bass bridge," according to the ad. Lemke also says that the bass was used to win BYU's Battle of the Bands in 2008 and also to record Imagine Dragons' self-titled debut EP.

In case you're wondering, a typical Fender Squire bass goes for about $150 to $500, but Lemke believes the bass is worth much more than that. "There's so much mania out there," Lemke says. "Imagine Dragons is becoming so famous and popular, so I'm like, 'Well, let's see.'"  

It's not uncommon for a musician to auction off or sell a prized musical instrument. One of the most expensive basses ever sold belonged to John Entwistle, bassist for The Who. He sold his ax Frankenstein at an auction in 2003 for what was considered a "staggering" $100,400. According to Fender, the bass sold at "nearly 10 times its expected price."
