Report Review for product Tube Converter - Yellow Jacket® YJS, for fixed-biased tubes

Tonal game changer for me! The Yellow Jacket YJS allowed me to achieve the natural overdrive tone I was seeking in my JCM 800 and my 59 Bassman Reissue without having to crank the amps to an ear splitting volume. I have tried power soaks and pedals but nothing compares to the simplicity of using the Yellow Jacket YJS.
