Topic: That "Pull Thick" Control - what kind of circuit |

I have an old Peavey Backstage Plus amp I bought used when I had cramped living spaces to live in. Not the perfect steel guitar amp, but it had some nice features.
The feature I'm curious about is the "High" knob in the EQ section, also labeled "Pull Thick". When in the pulled position, it gives more body/thickness to the notes being played.
It's kind of nice in certain kinds of E9th picking; sometimes I wish I had access to an effect like it.
It doesn't seem like a compressor circuit - in that there's no additional sustain, but on the other hand it's similar to the initial attack effect of a compressor. So I plead ignorance.
They're not seen much anymore, but does anybody remember what kind of circuit might be behind this control?
Thanks, BK |

It's a mid boost

Jay,
Thanks for the answer.
I'm having a little trouble processing the mid-boost idea within my present concepts about steel pickups - that is, that there's already a midrange hump, and that it's mostly unwanted. And that's behind the idea of the adjustable midrange cut or boost range on most steel amps.
Also, the Peavey Backstage has Bass, Mid and High eq controls (probably passive), the Pull Thick being on the High control.
When the Pull Thick is activated the result is "good" (to my ear) and doesn't seem to be equivalent to boosting the mids. But I've been wrong a lot of times.
Could you maybe elaborate a little on your answer?
Thanks in advance for any additional info.
BK |
