This is the circuit diagram of DOD FX75 Flanger guitar effect pedal. The circuit drawn by Fabian P. Hartery Components description: CD4007 dual complementary pair with inverter; (RCA) TL022C low power dual operating amplifier; (texas instruments) MN3007 audio signal delay, 1024 stage low noise BBD (5.12-51.2 msec delay) MN3101 clock generator for Bucket Brigade Device/BBD MN3101/MN3007 manfufactured by Panasonic; these are equivalent To ECG1639/ECG1641 respectfully
This is the electro harmonix fuzz-wah guitar effect pedal circuit diagram. Circuit Notes: Q1 & Q2 are 2n3565 Fuzz bypass S1 has been improved to provide true bypass S3 chooses volume or wah-wah S5 provides for sweep reverse S2 gives just fuzz, just wah-wah / volume, or fuzz into wah-wah / volume S4 sets tone of filter D1 & D2 can be any signal diode
This is the schematic diagram of Electro-Harmonix Small Stone Phaser guitar effect pedal. The Small Stone is somewhat special in applying Operational Transconductance Amplifiers (OTA’s) for phase shift stages rather of opamps with variable resistors. All of the IC’s are house marked EH1048, but could be replaced with CA3094 that is a combination of an OTA equal with the CA3080 as well as a darlington emitter follower. Later Small Stones [...]
