Why do we call it "FAT". Saw Dennis Gruenling at a very small club in Pittsburgh this weekend. Great show and beautiful round hornlike tone from his shiny chrome bullet and 6X10 Harpking. It was a tone which I'm sure we would all describe as fat. But, part of the quality of it was the high frequencies, which we might call shrill were gone. My guess is maybe no frequencies greater than about 8khz. So I'm wondering since the frequency band has actually been narrowed, why do we call it "fat".

We call it fat because of the enhanced low frequencies which make the sound much bigger. High frequencies are more like fly-away hair and long fingernails. They don't weigh much, they're just annoying.

Was he at Moondogs? I doubt that the harp gets anywhere near 8K. I have tried to find the frequency response range of diatonic harmonics on the web. No luck...BN

Guess I'm way off on the kHz but it seems if I use a low pass filter at 8khz it makes a big difference. Maybe it's overtones?

To get "fat" harmonica tone, pump 240-250 hz.

When you're in the studio and want the harp to pop, boost 8K.

The HarpKing 6x10 is a huge fat sounding amp, with a ton of bass, and yes it does have some hornlike qualities.

Have found that HarpKing has its own unique tone - different from other amps. I'm not a fan of it, but many players are. It certainly is a loud amp, though.

Fat is, as greg says, more low mids tha highs, and that is what you get whit a good cup: lots of lows, a few highs.
Also, playing whit my behringer eq pedal some time ago, I found that when you push the 200-250hz slider up you get more bass, but when you push the 400hz area, that is where the real fatnes lives, in the low-but-no-so-low-mids.

Re: why cutting after 8k makes a difference to the tone if the fundamental frequencies aren't over ~4k. Remember, there are fundamental tones, and then harmonics. Harmonics appear at various fractions of the fundamental tones being played. Even fractions sound different than odd ones, and higher order harmonics sound different than lower order ones. The combination of fundamental tones and the various harmonics are what give an instrument a particular tone (or timbre). When you set your eq of your instrument (with a pedal, on the amp, or with playing techniques), you are changing the range of harmonic frequencies that pass through (audibly), and thus change the total percieved tone of your instrument.
