Ovation preamp schematic

[sonicguitars]

I think could be interesting tio have something also for acoustic guitars. Here is schematic of Ovation piezo preamp. I thing is not so difficult but I'm not the specialist

Hmm.. Simple enough. The inductors do bother me though.. We haven't used inductors or transformers on any of our layouts. I think i should ask Mark's opinion about this.

I wasn't sure if they were micro or milli, but looking at another scheme the inductors seem to be µH but I don't really know much about them or what type to use.  Are the axial ones like this suitable:

If so they would be pretty cool because they're physically like resistors and so would suit our type of layout.

Tayda has those too. Exactly like resistors. Only thing is that there's no component image for inductors in DIYLC3...

I've got one made up in V2, just like a little green resistor, so I'll do it

Good!

This is my vero layout:

Is my first vero conversion, cam you be so kind to give me an opinion if could or if you see some mistakes?
Thanks anyway!
