EL34B STR Ruby Tubes

Used these to replace the stock EH EL34's in one of my amp heads, a Peavey JSX. Prior to the swap the JSX suffered from a tremendous lack of depth and fullness so on a whim I tried these and let me tell you the change for the better once I put these in and biased it up. Tighter thicker low end punch, a warmer midrange that cuts through without sounding boxy and controlled highs that are detailed but not shrillike or overabundant. These made this head go from a Hyundai to a Ferrari in the tone department. I did swap the preamp tubes as well but this was way too noticable of a difference not to report on it. I wonder how these would sound in one of my Marshall heads? Anyway a great buy for my JSX.
