I've recently discovered the ellis stomp box...and it looks like a fantastic product.

But I feel like I could probably make myself one for less then $200.

Does anyone know of any tutorials or have any insight on how to go about this? I know essentially you take a piezio element and stick it between two pieces of wood, but I'm pretty sure a preamp, some sort of volume control, and a filter on it would make it much better.

Partscaster/Tele into a bunch of pedals, a Maz 18 head, and a Z Best cab.
Im not sure...I was just thinking the same as you about the piezo into a block of wood somhow...maybe just attach it to the underside or somthing...I have no idea...googled?

Also caught her playing fallout boy on my guitar, changed my strings and cleaned it the next day.
Had a squiz but so far nothing from there. Interesting forum though.
I'll have more of a dig later though.
