"In addition to the MC33178 chip, the 805’s circuit employs back-to-back stacked glass diodes to generate distortion and provide up to 36dB of gain."
glass diodes?? is that a fancy way to say silicon... silica...glass? which one of these is GLASS?

honestly either one of the 808 drives, plus post EQ to taste, since you can only move the middle freq center you could use a PEQ block after the drive to center all the tone knobs like they are on the 805. I spent years chasing this elusive DS-1 majic voodoo tone, it turned out to be a ~7dB dip at 500Hz from the tone control being a highpass and lowpass filter combined, and a certain clipping diode type...it wasn't some mystical unicorn pixie dust distortion that made it awesome, it was a ~7dB dip at 500Hz and a diode swap. Now any drive I use I can make it do what I want, and they all sound badass.
