I'm putting these custom made wooden knobs up for sale. They came on my MTD Z6 when I purchased it but I replaced these knobs with ones that I like better. I just don't want these to sit in a drawer. I figure someone could put them to use. It's five knobs. Here's a picture of the knobs on the bass. The bass is not for sale, only the knobs. I'll let them go for $30 shipped. Paypal please.
