This is the design diagram of 5 band graphic equaliser circuit build using operational amplifier chips, the NE5532 or LM833. The op-amp ICs is a good choice because of inexpensive and comes with fairly good quality output. Each IC contains dual op-amps circuit, so you will need 4 ICs of NE5532 or LM833 to build… Read More »
This is another stereo / dual power amplifier circuit with power IC KA series. This amplifier delivers dual power output (stereo) at 1.2W for each channel. General The KA2214 is a monolithic integrated dual audio power amplifier in a 14-pin plastic dual in line package. It is designed portable audio sets.
The following image is the scheme diagram of six LED stereo VU display circuit which build using Dot/Bar Display Driver IC LM3915. This VU display should be connected before amplifier module circuit. You may connect this circuit at pre-amp output, tone control input/output or equaliser input/output. This circuit powered with 12V DC supply. About LM3915:… Read More »
The Univibe is actually a footpedal-operated phaser or phase shifter for generating chorus and vibrato simulations for electric organ or guitar. It was introduced in the 1960s by Shin-ei, and was intended to emulate the “Doppler sound” of a Leslie speaker. Although not a really successful Leslie-simulator, the Univibe has turn out to be an… Read More »
This is the circuit diagram of Univox Super-Fuzz Pedal. This pedal is actually a 69-to-early 70″s design that consists of two special capabilities. They are the octave generation effect from the differential-pair-with-collectors -tied-together along with the option of just a clipping amplifier or a 1kHz notch for different sounds.
This is the circuit diagram of Vox Tone Bender Pedal. The circuit is very similar to Fuzz Face pedal. The Vox ToneBender will have a lot more treble response than the Fuzz Face…maybe to help brighten up those characteristically “dark” sounding British amps some. Using a Vox ToneBender with a Fender Twin, or any other… Read More »
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 »
Below diagram is the circuit diagram of Dan Amstrong Blue Clipper fuzz, effect for electric guitar: The Blue Clipper is a thick sounding fuzz with gargantuan sustain. The Blue Clipper delivers a nice, thick fuzz like the Muff, but this unit packs a little more bite. The big difference is that the gain level is… Read More »
