Obviously the one on the right is a Boss HM-2,...but what's on the left and is it worth 15 bucks. An old Tronix pedal to be sure but which one?

I had an old Tronix DS-710 distortion - which had three knobs like that, but it was black. It was worth about $5 - maybe.....$15 might be a risk, but get the HM-2!

Wow. I had a 10" Tronix combo amp that I got for free from a friend. Wow, it was horrible! I was so happy when it finally blew up!
I would ask the seller to give you $5 to take it from him.
