From the post
100 layouts! Thanks to everyone who visits the blog and a special thanks to those of you who have built and verified some of these layouts.
The Dr. Boogie is a JFET-based amp emulator of the Mesa Boogie Dual Rectifier Solo head, designed by ElectraTabs over on the DIYStompboxes forum. It creates a unique high-gain distortion effect.
Most layouts and builds of this effect I've seen are in 1590BB enclosures. This one should fit in a 1590B, but would probably be more comfortable in a 125B. Use right angle PCB mount pots and mount them to the board from the solder-side. Mind the EQ row of pots are oriented 180º differently from the top row of pots.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.

Check before you build · 4 values the reader of this layout was not sure of
- 20pF at row E, columns O-R (upper right): reads 20pF on both the board and the wiring diagram, but a leading 2 could be hidden under the pad (220pF); printed unusual value
- 30nF at row C (top centre): printed clearly, unusual value
- 5nF at row S (lower left): printed clearly, unusual value
- 2M vertical resistor at column C, rows H-K: printed clearly, unusual value
