Incredible post.

thank u

Pretty cool, I didn't know a lot of amps more or less followed the same EQ design

Nice. Who would've known that by backing off bass and treble and cranking mids you'd get a more or less flat EQ. I'll have to try that if only for fun.

What about the Selmer T'nB? That one only has Treble 'n Bass control (hence the name) do you know anything about that one?
I have been thinking about this amp too much. Maybe I should've bought it after all.

the scheme looks like a FMV with fixed mid control

This is great information. I had no idea that cranking everything in a common FMV EQ setup would result in a midrange (I've actually never really done that).

I have a Trace Elliot amp that uses a single tone knob, but they designed it so that, as you turned the knob clockwise, the midrange would decrease while the treble would increase. So you could get a midrange "boost" (it's passive so probably it's subtractive and relative EQ perception) turned counter clockwise, and a scooped treble boost the other way. It's very useful. There's also a bright switch that has a less dramatic effect the louder the amp gets, by design, which is nice for not razoring through everyone's eardrums.

That sounds like the Shape knob that some Orange amps use, like the TH100 and TH30 amps.

Nice post! Gotta try out more settings on my Marshall now. The Lemmy trick seems like a good thing in a band setting.

Any knowledge about the Sound City Mark IV active eq?

Yea in that EQ what they did was split the signal into 3 different passive filters, then had a gain stage for each filtered signal, and mixed them all back together

I read this twice when you posted on tb, (I sometimes lurk there) Glad you posted it here as well as I'm getting ready to dive back in. I think I get a little bit more with each read. Really awesome of you Nick

Digging out this old thread, i know, but can you do such a graphic for modern Matamps ? Gt1/Gt2? ;-)
Thanks,Pat

If I had a schematic I could
