My Bolsa bass is out of tune!

Hey my tech has emailed in about this already, and I have too, so now I’m doing it here:

My Bolsa bass has gone out of tune and it has to do with a broken part partially due to not have a buffer. Does critter offer a repair service or know anyone who can fix it for less than hundreds of dollars more than payed for said unit? @CGmedia I’d love help with this ASAP
