## Customer Reviews

### ⭐⭐⭐⭐⭐ Five Stars
*by M***T on February 3, 2018*

Awesome

### ⭐ Horrible b stock
*by M***L on June 12, 2023*

This pre amp must have come from b stock. I’ve used bartolini pickups and pre amp for over twenty years and this has been my worst experience. It had a very loud hum, no one could repair it.Very disappointed with this vendor.

### ⭐⭐⭐⭐ Good deal but.
*by C***Y on February 12, 2016*

First off this is a great preamp however upon opening the box i found one wire loose from the blend pot. I referred to the wiring diagram and reattached it but had another come loose upon installation. After that was fixed all is good. The wires seem a bit fragile but work well.
