No one have guts or schematic of this pedal(super lead or super bass)?

Is quite impossible find information about. I only know it's based on the marshall preamp...

Thanks to all [smilie=a_cool.gif]

Yes, please! I've scoured the web as well to find either the Revelation or Oath schematic and found nothing other than an indiscernible gut shot. Would love to build this one...

Someone is selling one of the prototypes on reverb. If i had any guess its probably close tho pharaoh specks with all the tone control parts removed, no no third stage diode clipping, and a pre gain.

Broke down and bought a Revelation Super Bass. Brutal circuit into a crunchy amp or OD pedal. Took a peek and I think this is right except the 100K from P2 terminal 1 to ground which should be 1K.

Thank you. I was building a Pharaoh last week. I tested it out before got to the second clipping stage and tone section and was pleased by how good it sounded. It matches up (or more with the Deluxe, with the variable input gain pot) as AZX309 suspected.

The emitter off Q1, are you sure it's 100R and not 1k? The rest matches. I was going to try to draw something, but you can use your favorite Muff layout and stop at the tone stack. Thanks again!!

Yep, good catch. Two corrections need to be made to my hand drawn schematic: Q1 Emitter resistor and P2 terminal 1 should both be 1K not 100K.

I wonder if the SuperLEAD version is then based on the LSTR, as it's touted to be the more aggressive of the two.

You could use the layout our forum brother Nocentelli made for his Bikini Wax Fuzz and make a couple of adjustments.

Pic of my build using Nocentelli's layout. Use column "G" for your input coming off the pre-gain pot, which replaces R2:

Any time ! :thumbsup The schematic Stymie13 posted reminded me of the Bikini Wax, so there's no need to reinvent the wheel for the layout.
That's a tidy build you made and a great sound you're getting from it.

Thanks! It sounds so good I built the Ritual 1-knob fuzz to pair it with. There's also an effects order toggle in the middle . It's pretty quiet for something with so much fuzz bouncing around inside. It destroys...

Confirmed ! :thumbsup

The Super Bass is a stripped down Pharoah without the tone control, no clipping diodes in the 2nd gain stage, and an input gain control.
The Super Lead version is the same circuit, but with the values of the Black Arts LSTR.
