I have been fighting with shrill and buzzy distorsions from my amp for years now. This speaker is perfect match for my JCM800 2203, now it sounds bright, tight, with just enough bottom but not shrill at top end. It had always been a bad speaker that was messing up my sound. Tried lots of popular speakers and have never been even closely satisfied (v30(horrible), classic lead, celestion wolverine, HH-custom and so on) Only alternative that I would look at is G12-65 (it was found in old marshall cabs and it was a big factor in the sound that made them famous). Highly recommended.
