FM3 Buddha 5 machine (functioning but needs repair) Rare!

Description

You're bidding on a rare FM3 Buddha 5 machine that needs a repair (pitch shift wheel does not function). The bidder should be prepared to solicit a repair service or repair the machine themselves. Sold as is:
"Powers on and functions (samples play and sample switcher works) but the pitch shift wheel does not seem to function, so it likely needs a (simple?) repair. The plastic shell has been cleaned but has a tacky texture."
