1962 Duo Sonic – Only Better!

Custom Build by my brother Todd L. McCagg as my 2018 Brithday/Christmas present

My first guitar was a 1962 Fender Duo Sonic, my brother went to great lengths to not just reproduce that guitar that build it with the best modern hardware available.

  • Fender donor body
  • Warmoth Neck
  • Schaller Bridge
  • HipShot Tuners
  • Kent Armstrong Custom Wound Pickups
  • Switchcraft Switch and Jack
  • Bournes MIL Spec pots

Truly the sweetest guitar I have!


CozMcC Engineering Bus Sign

Reminiscent of the Netscape Engineering Bus Sign from back in the 90’s. The ESP8266 acts as a web server passing off the input text to the nano which displays it on the LED Matrix


  • Arduino Nano
  • MAX7219 LED Matrix Display Module
  • ESP8266 ESP01 Module
  • Active Piezo Buzzer



This is the ESP8266 System on a Chip
