The following diagram is the schematic of Gibson RD Artist bass guitar Circuit Notes: Both compression and expansion effects are determined by the lead pickup output only. I and O in the design diagram refer to inner and outer connections for the specific plug / jack. P and J in the design diagram refer to… Read More »
This is the circuit diagram of DOD FX75 Flanger guitar effect pedal. The circuit drawn by Fabian P. Hartery. Featuring a Width control and two output jacks, the FX75 was much more versatile than its predecessor, but the flanging effect it could provide was still not very intense. That said, chorus-like washes of flange can… Read More »
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… Read More »
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… Read More »
This is a simple and low cost Tube Head Vacuum Tube pre-amp circuit designed bu PAiA electronics: Vcc – Pin 1 IC1 +12v – Pin 8 IC2, IC3, IC4 -12v – Pin 4 IC2, IC3, IC4 Ground – Pin 8 IC1 IC1 – 4049 CMOS Hex Inverting Buffer IC2, 3, 4 – 5532 Dual Low-Noise… Read More »
This document contains schematic diagram of Orange 125MK3 including the guitar preamp section, feedback and power amplifier section. Preview:
This motion filter effect circuit will controls the initial frequency and controls how much the envelope follower responds to the input signal. An envelope follower/filter combination translates the typical dynamic properties of your axe into modulated timbral changes too, you could feel of it as an automatic wah-wah pedal. Independent Initial Frequency and Sensitivity knobs… Read More »
The following diagram is the Jimi Hendrix Fuzz Face Pedal JH-2 circuit diagram. Schematic by Jim Dunlop Note: Q1 & Q2 are MPSA18
This is the circuit diagram of Fuzz Face mods, guitar effect pedal. This is a modified diagram and simpler than the original Fuzz Face diagram. You will find apparently two identical designs of the fuzz face. In one Q1 and Q2 had been PNP germanium AC128 or NKT275 types, in the other they had been… Read More »
