Cool document! Looks like a lot to take in. I really want to understand more about this side of instrument building so this kind of thing is much appreciated. I will share out with my bass building friends!

FYI, doesn't seem to open in Chrome? Maybe it's just me. Worked find in FF and IE.

Its nice to see an in depth report on the design of an analogue device in a world cluttered with binary. Wow slew rate, common mode rejection, clipping and the like, love those terms. It also shows that in spite of the digital revolution its still very much an analogue world we live in and experience.

I am not a musician and don't know much about analog circuits but one thing I could tell is that it was a work of love. Someone has to be really passionate about the topic to write and share that. I admire that.

I'm a little confused about the Final schematic. There are unlabeled wires floating around, and even after reading the whole document I'm confused as to where exactly the EQ modules fit into the design. Can anyone shed some light on how these pieces fit together?

TLO7x? Really? There are better opamps out there.

Such as?

This article has a nice shoot-out between opamps:

The OPA2209 looks pretty nice - an order of magnitude less noise and two orders of magnitude less distortion than the TL072.

If you look on the previous page, it is the same schematic with everything connected.

In general, Burr-Brown, THAT corporation, some of Linear Technology's offerings... the rest will be the usual datasheet pain and suffering to find the best fit for the application.
