Emanating Fist Electronics Dope Priest - Frequency Sustainer

From the captain:


Take 3. D*A*M Ram Head -> Emanating Fist Electronics XB-70 -> Emanating Fist Electronics Dope Priest. Same shit just a little more refined with an air of maturity, if the Ram Head was a bottle of Jim Beam the Priest is a bottle of Wild Turkey. As with the XB-70 the core circuit influence here is my slowly decaying 1977 Guild Foxey Lady though this time the circuit blue print is tailored to my own ears and tastes rather than just replication. I've taken some influence from V3 Sovteks and the Triangle Muffs, basically lowered background noise, tighter projection and greater ability to cut through dense frequencies. It ain't no reinvention of the wheel just the delivery of sounds that I dig in regards to this circuit type presented in way that appeals to me more than our past incarnations.

  1. D5 is marked but not listed as to what it is, there are 2 listings D1-D4 as 1n914 and a D1 as 1n5187?

  2. Built and using 2n5088's in sockets for the moment. The original uses BC549C's Thank you so much!

    1. And it just really came alive using 2n5089's I'll try to get a hold of a quartet of BC549C's (like the original) or BC550C's.

  3. Awesome! Is there a schematic available? Didnt find it on FSB.

    1. There isn't. It's just s big muff with some value differences. Worked on it from gutshots.

  4. Awesome. Thanks for posting that layout. High on the "to-build" list.

  5. Built and sounds good. The BMP tone-stack on this one is quite nice. Lots of usable area in the EQ control.

  6. Original unit seems to be using BC549C trannies.

    "Offering unrivalled midrange projection with total clarity the Dope Priest features highly articulate dynamics for such and intense distortion device. The four stage circuit is carefully tuned with a gain selected quartet of BC549C's, selected for their sonic similarities to the obsolete BC239C."

    1. yep. just figured not everyone would have BC549C's laying around. i'll change the notes though since it's been mentioned multiple times.

  7. Fired up first try. Used 2N5089's, sounds great to me. Thanks for the layout!

  8. Apologies if this is a dumb question, the 100uF Electrolytic, is the negative leg going to ground? I can see lil (-) symbols on the 1uF's. But not on the 100.

    While I'm asking potentially dumb questions, Mids switch; is that a DPDT (on/on/on)? SW1 is coming from the board to the switch, the switch to Tone 3 is that going to Tone 3 on the pot? That's not the Tone 3 from the Vero board is it?

    Appreciate the advice thanks everyone.
