Guitar Effect - Fat Cat Distortion Pedal

Rangkaian Guitar Effect - Fat Cat Distortion Pedal

circuit of Fat Cat Distortion pedal Distortion is good for blues, rock, pop and alternative. by using this circuit You can hear the fat tone, even at maximum overdrive.

The transistor 2SC1815/BC546 is configured as voltage follower, giving a high impedance for the input. The op-amp serve an adjustable gain amplifier, to boost the signal until it reach the forward bias voltage (about 0.7 volts) of 1N4148 diodes, where the signal is clipped.

The tone controller in use adding a high frequency attenuation when the resistance is set to higher values. Finally, 2SK188/BF245 field effect transistors (FET) is used to buffer the tone control circuit to give low output impedance. Without this buffer, the tone controller would also act like a volume control when the output is connected to a low impedance input.

Quick data IC OP-Amp 5534

The NE5534, NE5534A, SE5534, and SE5534A are monolithic high-performance operational amplifiers combining excellent dc and ac characteristics. Some of the features include very low noise, high output drive capability, high unitygain and maximum-output-swing bandwidths, low distortion, and high slew rate.
