General guideline for components Capacitors: All values under 1nF should be ceramic disks. From 1nF up to 1uF should be MKT (foil/metalfilm capacitors) and over 1uF use electrolyte caps (or tantalum) 16V+ rated and watch out for polarity! Resistors: use 1% metalfilm for the best results.
Off board wiring Anode (long leg) Cathode (short leg) R led Sleeve Input Jack R led Ring Ring Output Jack Footswitch Blue = pin 1 White = pin 2 Yellow = pin 3 NB. If you do not want to use the D1 diode than remember to short it by soldering a lead instead. NB 2.
Biasing This layout requires high grade potmeters, capacitators and trimpot to work as expected. The trimpot is used to bias the transistors Q1 and Q2. Start in the middle position and experiment which setting suits your tonal taste best. Also test it with Wrath on and off. If you only get squealing then adjust the trimpot.
