EP update

Exciting things on the Electric Princess front. We think we have the solutions to the Z+ gain stage, 

The electronics designer's modification to the Z+ gain stage. 

and to the 100Hz gain stage. 

 10K trim pot -> 1K

 C301 -> 0.47uf (470nf) C302 -> 1uf C304 - 0.1uf (100nf)

In addition: Put the trim pot on the opposite side of the board. Write "Electric Princess v.XXX" on the silkscreen Label each potentiometers' value on the silkscreen

Electric Princess Overdrive (Beta) First Look

 I have to give credit to Chance Shirley for the excellent graphic design on this pedal.

Here's a little video where I go through the functions. 

For Example

 I'm having a devil of a time with the Electric Princess overdrive. It's not even properly doing bypass. A lot of troubleshooting has happened. Much more will come. 

One issue of rather low importance right now is that one of the potentiometers is an audio reverse log at 5kΩ. There's a whole technique to rebuilding your own pots. But there's no way I'm going to do that. I'm sure just switching the pins on the PCB will allow me to get a regular 5k pot in there. 

That is, once the dang thing works. 

Ooh. I got bypass to work. Just not on a switch yet.

Electric Princess Overdrive PCB

 I got my set of five PCB's for the Electric Princess Overdrive from JLC. 

I'm still waiting on getting hardware parts. They're all coming with the enclosures. But the resistors, transistors, and capacitors are (almost) all SMD and were picked and placed and soldered by JLC. The switches, jacks, and pots need to be soldered by me. I'm just champing at the bit to get the parts.

Announcing the Electric Princess Overdrive

Here's a pre-production image of the top of my guitar pedal. The name has been changed to the Electric Princess Overdrive. The always brilliant Chance Shirley designed it. 

Here is the schematic. There are two gain stages: one that is based on an "Electro Harmonix Linear Power Boost" (but I think with slightly different cap values and a different transistor?), the other is based on the obnoxiously-named "Super Hard On" by Zvex. 

In-between those stages are two passive equalizers. One was a circuit I found using the Seymour Duncan EQ app (that's called the "Stack" in the Electric Princess Overdrive) and the other is the 100cps portion of a Pultec EQP1 where one can boost and cut simultaneously and it sounds cool. 

Have I put a completed one together yet? Heck no. I've tested everything except for the Pultec and I really like how it sounds though.
