We do not have such a schematic. If you are unclear on how this would be installed in an amp, we advise you consult a professional repair tech.

Shipment has been on-time delivered, and the product received in secured packaging is the same as my order. No product test has been made so far.

While building a new amp I found this item and tried it. It's great, sounds good, easy to design in electrically, and very small & light. Yes, it does sound good, you'd never know there wasn't a spring in my amp. It doesn't give you that twang sound when you bang the top of your amp, oh well, can't have everything!
