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.

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.
