Electro harmonix graphic equalizer circuit

Posted on Feb 6, 2014

This is the diagram od electro-harmonix graphic equalizer. You can specify the number of channels according to your needs. You just need to parallel the components: C1, C2, R1, an om-amp, Potensiometer and a 470 ohm resistor. The frequency to be boost decided by C1, C2 and R1. See the diagram for the C1, C2. This is the circuit diagram of Electro

-Harmonix Soul Preacher pedal. Notes: -All resistors are carbon film, 1/4W, 5%, unless otherwise noted -All non-polarized capacitors are mylar, 50V, 10%, unless otherwise noted -Transistors Q1-4 and FET J1 are unknown -IC1 is a 4558 Download Electro-Harmonix Soul Preacher pedal circuit diagram in PDF file: » Download Link 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. The following diagram is the schematic diagram of electric guitar effect: Electro Harmonix (EH) Big Muff Pi. The EH Big Muff Pi would probably be better making the change by a modern input-jack power and a DPDT bypass switch. The types of transistors and diodes are unknown. It is likely that any high gain NPN. 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.
