This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

MI Audio Blues Boy Deluxe

 Stumbled across the schematic for this one over on FSB and it seemed interesting enough. Should be able to squeeze it into a 1590B.

  4. It seems to me that the 22nF capacitor at the output should be 2.2nF

  10. Vi algo errado no Layout... O pino 1 & 2 do Pot de Médio está indo para o VREF, sendo que, no Schematic, o pino 1 do Pot de Médio vai para o resistor de 2K2 e o mesmo vai para VREF... Enquanto o os pinos 2 & 3 vão para o pino 3 do Pot de Tone...
