    Hi,

    I have seen this before on "guitar store" web sites. I am not into guitar amps but I believe the "soft, medium or hard" has something to do with how the tubes react when driven to the point at which they will distort (clipping) in a guitar amp. I do not believe that this "characteristic" is relevent when the tube is used as an audio amplifier in a hi-fi situation. Possibly someone who is into tube guitar amplifiers could weigh in here and give a better explanation.

    Bob is correct. Guitar center is rating for the ability to breakup early, which is something that a guitar player would want for that "bluesbreaker" sound (soft set). For audio applications you don't want them to clip at all so, you'd want the "hard" set.

    I ordered The soft tube set after getting this from there site.



    Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. Soft-rated tubes break up slow and have the highest amount of headroom, while hard-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. Medium-rated tubes fall in between.
