Well it’s all relative. If I compared the 1987 Jubilee I had to the Friedman’s it would come off raw & aggressive comparatively. It’s been a few years now since I had that jubilee, but going off what I remember it was definitely smoother in the mids vs the ‘79 jmp2203, but I wanna say it may have just overall been smoother throughout like you said
I agree that some amps can have smoother top end, but the aggressive mids make it overall a not at all polite amp. Kinda like the iii’s vs c+’s. The iii’s have more aggressive/sharper highs, but c+’s seemed to have more growl and tonal complexity other than the highs, so to the c+’s sounded overall more aggressive to me IME and just plain better. My Purpleface is a perfect example I think of what you’re describing. It has smooth, silky, somewhat rolled off highs, not a huge low end (but not lacking to me either), but throughout the entire midrange spectrum extremely rich, growly, complex and aggressive. It is the complete opposite of amps with hollowness in the mids like Hiwatt’s, Fryette’s, Wizard’s
