In Part 2 of this video series on the vintage Ampeg G-12 Gemini tube combo, we will discuss how to make a new optocoupler or photocoupler, aka "roach", for the tremolo and we'll finally hear this beast in action. As a special treat, my friend Don Oswald will do the honors in the demo today! Check out his band D Man & the Alley Hounds:
