The only clue related to tap tempo is from Patreon EAGLE board for Tap Tempo. It does require an AVR and an MPC. Both of them are 8 pins. Otherwise, I'll go with Taprecise from Marshall Arts. I was looking to this for my Mega Pedal build.

Anybody know how to do the tap tempo mod for the Blueprint?

OK -- I misunderstood the role played by the opto-coupler in the circuit.  In that case, seems like the question would be whether Q1 is functioning properly (input and output).

You might also check that the wires coming into the board have not strays touching something they should not -- I've had that problem before.

Azabache x 1000.

I'm just going to list it as my favorite overdrive, and possibly my favorite dirt pedal overall. It's the only dirt pedal except for my winnie the pooh fuzz face that earned a permanent spot on my main board in the last two years (and for a while, it replaced my fuzz face as the only dirt pedal I was using).

The Wampler has slightly more clarity in some settings, and its gain structure is almost identical, but the Azabache for me nudges it out on "feel" (slightly more sponginess) and simplicity (the EQ is surprisingly versatile even without the extra controls). The bright switch on the Azabache is particularly great for the higher gain sounds, because it cuts treble BEFORE the distortion, whereas the Wampler can only cut it after. So the Azabache intermodulates less on higher gain settings, without needing to fiddle with your guitar tone pot when switching your overdrive on and off.

The only change I would make when building the Azabache is to make the last set of diodes asymmetrical.

I really need to make a demo of it. Maybe I'll do that tonight while I'm shooting the vid for my contest entry.

Hey Jon,

Sorry for reviving an old thread but I'm seriously thinking about building an Azabache. I thought about the Black 65 first then saw your message.
Did you use the treble mod to get less treble out of it? (lowering R5 that's connected to pin 1 of the tone pot)
I've always wanted to have a Black 65 but am afraid of all the pots (3 band EQ is too much for me) and it looks a bit tricky to bias. So now I'm thinking of the Azabache.

Cheers! :D

have you checked to see if you are getting variable resistance from the opto-coupler?  the flashing LED suggests you are getting variable voltage going to it, but the part may be defective.

That should not be causing the effect he's describing. The opto is only for the ramping control and the internal photocell only reacts to input...it won't flash on its own (it's separate from the LFO). Rather, the JFET (q1) is used as a variable resistor to modulate the signal amplitude for the trem effect.

Oh well, figured something like that. They look cool.. :o

...added some shielded cable yesterday - I can recommend that for any high-gain-pedal build!

I personally approve any pedal with Stacey Rozich artwork on it.
