PS-100 Sounds very dark even after full retube

OK,

So it would be easy for you to return it to the factory as you are based in US. Quite a few customers are international.

Here is the option for a factory repair How can I send my product to Fryette for a repair?

Or if you know a local shops that will look at it, Can I get my Fryette product repaired at a local repair shop?

Post back here if you need anything else.
