I wouldn’t call it polished, just more open. I didn’t care for the JB in my R8 but the Hot Head worked. Enough push to hit the front end of the amp but still has clear highs.
Gibby spaced, yes.
I haven’t tried the Detroiter but had 2nd Degree Black Belts and the Hot Head is hotter than the 2nd° BB. You still have clarity when rolling your guitar volume down.
I have a 1959 reissue and a ‘74 Super Lead both with the BE Mod. Not exactly what you’re asking but reissue is more ballsy. It was that way stock, they’ll be close but each amp has it’s own personality.
