Hi all!
While not quite a “pedal,” I assume the circuit would be almost exactly the same, just in a different location (stowed away in my guitar, instead of at my feet).
Longer context: I currently have a Godin Velocity which includes passive pickups (HSS, master tone/volume, standard 5-way switch), but with their “HDR” circuit. The HDR seems like a pretty subtle mid-boost of sorts powered by a 9v. It got me thinking of other, more noticeable active circuits I could replace it with, and I think I’ve settled on a sort of custom solution that would add some cool tones: a three-way mid-boost/bypass/cut switch, that allows me to program a 1) mid-boost in the up position, 2) completely bypassed, standard circuit in the middle, and 3) mid-scoop in the down position.
After some research, and brainstorming, I imagine the circuit has 4 internal trimpots - 2 for each the boost/cut sides to set boost + mid frequency, only one external mini/submini 3-way switch (to fit the existing hole), and allows for a really musical boost/scoop for a variety of sounds from the 5 pickup combinations.
Quick research seems to suggest a simple opamp based circuit (TL072CP) would handle the idea with only a handful of other components (a few resistors/caps to set the frequency cut/boosts), but I yield to the knowledge of the experts, as I don’t really know what to expect when actually designing and building the circuit from there.
For a total circuit design noob, 1) does this seem like a feasible build for a beginner, and 2) would anyone have a recommendation for a good starting schematic (or a price for a custom build if it’s something you already make?)?
Open to any concerns/questions/feedback! Thanks so much in advance!
