This is a brand new Joyo tremolo complete with Demeter mod. It's a fabulous sounding tremolo without the mod, but a few tweaks bring it right into line with the Demeter Tremulator (which I do own). I've also moved the bias and level controls to the top for even more versatility. The bias goes from a smooth, subtle trem counter clockwise to a full on chop clockwise. The level control allows you to balance your output or even use it as a boost.

I've also upgraded the electrolytic caps to something a bit nicer. Why? Why not? It makes a subtle difference that I like.

Comes in original box.
