BOSS: OD-1 Overdrive

A classic Boss overdrive - the one that started it all for Boss guitar effects, originally sold from 1977 to 1985.   This is one of the later designs that does not use the quad opamp.

Kind of curious that after this, many designs used the Boss version of a discrete opamp that can be seen in several different designs.

BOSS OD-1 OVERDRIVE - VIDEO DEMO

Not strictly speaking a straight demo of the OD-1, but I like Wampler's videos, and this does have a good comparison of the SD-1 and OD-3.
