This is the 3x3 set that I just took off of my Mushok. 9/10 condition, not bad for what they are, but not great either. They're off a baritone, and fit up to a 68.
They aren't an upgrade from anything, but if someone's looking for some cheap 3x3s doing a hardware swap, or looking for an inexpensive way to run bigger strings for tuning down, $20 shipped and they're all yours. Paypal/CONUS only. Comes with a free MG sticker.
