I had discovered an interesting overdrive schematic from BYOC. It’s called the British Blues Overdrive. What I had found interesting is that it uses the VREF voltage from the voltage divider in the Gain, Tone and Volume stages. The British Blues Overdrive is designed very differently than any other overdrive I have. I must say, the BBOD sounds awesome. I made only one change. I have used a 250K potentiometer for the Gain stage instead of the 100K. It’s because I wanted more bite.
I have been using the BBOD after my Boss MT-2 Metal Zone distortion. The BBOD helps to increase the harmonic range when playing. It also broadens the depth of the sound like an OD would. Try it out.
