Maxon’s now discontinued Overdrive / Soft Distortion pedal. Brother to the very popular OD820 and in the same series with the same size case. This layout uses two dual opamps instead of the 3 singles in the original to keep the layout size down. The equivalent of the LM741 in dual opamp form is probably the LM1458, but it’s worth trying this with the other popular dual opamps as well such as the JRC4558, NE5532 and TL072 etc, so you can use your favourite.
