Ibanez No. 58 Standard Wau Fuzz - Fuzz section
Based on the Ibanez No. 58 Standard Wau Fuzz - Fuzz section
From the post
Similar to the Ibanez No 59 Standard Fuzz but with a different tone section and a few extra resistors. If you want a bit more overall output level, 47k resistor connecting to Balance 3 could be can be replaced with a small value or a jumper. Another useful mod is to sub the germanium diodes with silicons for more crunch and tighter, louder fuzz.
