Can people tell me if there are any reasons this circuit shouldn't make a kick-ass Pultec style EQ? I'm planning on 2 toroid inductors (one molypermalloy for the smaller one, one ferrite for the larger one). Notice there's some funky inductor series/parallel switching going on (and switched parallel capacitors). I believe the actual Pultec's did a bit of this also. Most of the design inspiration is from a filter schematic labeled "EQP-1R Equalizer" in the Pultec EQP-1a manual PDF found on danalexanderaudio.com
I am also desperate to find out what capacitors the original Pultec's had where, if anyone can help me. I was thinking of putting some caps with significant "Character" in the key positions (ie. those that are in circuit all the time)
Forgive the schematic, I haven't used "Eagle" before.
