(D1 & D2 are 1n4001 type)
Here's some of the description from the Lovepedal site (apparently these pedals are only stocked in Guitar Centre!);
"The all-new Lovepedal Superlead is an incredible pedal produced just for Guitar Center. No one else has it. The Superlead packs thick, cranked British stack tone into a user-friendly, 3-knob pedal. Turn the gain down for a tough, percussive chunk, or crank it for singing, liquid lead tones with sustain for days. A two-position Mid switch offers your choice of boosted mids for a thicker sound or a more open voicing that lets the tone breathe. Whatever setting you choose, the Superlead delivers impeccable tone that responds to every nuance of your picking. Guitarists rejoice, your quest for the ultimate drive ends here. Check out the all new Lovepedal Superlead today, only at Guitar Center."
Here's a decent demo video as well;
And a vero layout by IvIark (even though he's marked d1 & 2 1n4148, they are 1n4001 as far as I'm aware, the difference in tone will be insignificant though);
