Angry Llama Build Instructions 

Based on one of the most popular DIY Builds the original Red Llama™ by Way Huge™. Our version also includes an 

added Gain Stage for those people want more available Gain (Distortion).  We do this without sacrificing the original 

circuits unique tone by adding a clean stage at the end of the circuit. Furthermore, we used Gain mapping to make it 

when the Boost control is turned down full CCW you get the exact same great tone as the original Llama with the 

ability to add more Gain by turning the Boost control up CW from there. This will create more available distortion 

than the original circuit while preserving the character of the original. We have also added a Hot Switch at SW1. Use 

these options separately or together to adjust your final sound or set Boost to full CCW for stock tone.
