The 797 lofi overdrive is my take on a vintage overdrive circuit. Simple to use, lots of output boost (15dB), low noise.

 Based around the 250 overdrive/preamp, I ended up doubling the component count to shape the overall tone, gain character, and significantly reduce the noise floor. I'm also using a 'premium' audio-grade op-amp for maximum fidelity & zero slew-rate distortion
