For a START on this issue, (not a full-on Mark Hammer solution, but a flexible and fun-to-experiment-with EQ) I can recommend the Craig Anderton Super Tone Control (it's project #17 in EPFM.)

So this shakes out as pretty much a DIY PQ-4, I guess. Much needed.

My own take on EQ for guitar has become something like this -

A bass shelving filter below 300 hz into a high-pass sweepable from about 60 hz (detuned guitar) up to 600 hz (cut mud zone).
A treble shelving filter above 3 khz into a low-pass sweepable from 10khz down to 1khz.

I figure that this would give you a 2-pole-ish effect (a shelf boost into a cut), and provide enough range that you could provide a relatively flat response (low db shelving, cuts at 60 hz and 10 khz) to emphasizing as much treble/bass as you need, simulating a mid-cut, all that.

4 knobs - high-pass, low-shelf boost/cut, high-shelf boost/cut, low-pass, and a level, so 5 knobs. Make each boost/shelf dual concentric and you're down to only 3... this type of pedal would be incredibly useful in the FX loop or after a line-out... Being me, I would want to build in a simple compressor/limiter, because that's one of the biggest things I wish I had on my board, so another knob for that... but you can't always get what you want.  =)


From a studio recording perspective, it would be awesome to have solid-state tube replacements that had some EQ options built in. For instance, a switchable 80 or 150 hz high-cut would instantly tighten up a guitarist's tone and make it more suitable for recording (or just tame an amp's or speaker's flabby bass response, even). A built-in line out would be totally saah-weeet, too, for amps that don't have one.

It seems like its possible, and seems like it would have a market if guitarists understood why high-cuts are important for tone control...

Okay....

I decided to make a start on this custom EQ thing. Here's what i have so far...





That looks so botique!  Did you vector-etch?  Does it sound good with a Nady wireless system, or just Nady patch cables because of the discreet vintage buffer?

And that would make the baby learning to crawl a guitar player?  :icon_lol:

I think that would make the baby learning to crawl a transistor.
