Although this is insufficient material to trace from,it is all I could find...

I installed an LED on my friend's ICBM, and decided to trace the circuit while I was at it. Was going to post it here, but only after I finished the layout did it dawn on me to compare the pedal to the original 77 op amp Big Muff schematic (courtesy of AG). Seems rather pointless at this juncture, and I'm far too demoralized to do so.

I'll list the differences for those who may be curious. Component numbering scheme consistent with AG's schematic.
IC 1 = MC1458
IC 2 = MC1741
C1 = 68nf (Input...

Hoping I could get some help here.

I'd like to have indepent control of the Dry and Wet signal.

Could I modify the single mix pot and use two mix pots instead? One for dry and one for wet?

Pot A
1 to Dry signal, 2 to output, 3 to ground

Pot B
1 to Wet signal, 2 to output, 3 to ground

Would this work?

Would I need some isolation resistors on leg 2 of both Pots to output?

Hi guys,
has anyone tried the Bogner Ecstasy Red pedal? From the youtube videos it looks awsome.

Thanks.

When I have made five posts, here will appear a link to the schematic of the Zvex Woolly Mammoth.

Here is a zip-file with the

So I have to start off by saying I build pedals. I am an Electrical engineer by Schooling but have moved to the dark side of sales LOL. I can understand a circuit. Sometimes I have to brush the cobwebs away with help but I have found that there are many like me. Some are NOOBS. Some learn over time some have a really good understanding and can do good designs and make fine pedals, but there are very few creative artists, who just transcend and come up with inspired unique designs; that just...

Anyon got any info on this?

It's a pt2399 based sample and hold type effect.

Thanks in advance

Anyone has schematics or information of modified points?
I heard that Bi Chorus composed with one PCB and two 3PDT foot switches...how switch two preset rate/depth?

August 7th 2009: All information on the KoT has been summarized into this King of Tone project page .
Please if you want to build, have built or want to repair nor modify this pedal look into the links on project page before starting a new thread. If you find mistake, typo's, dead links or anything else that shouldn't be there, please use the Report button

i find it surprising no one has brought this one up yet?

ive always been keen to see whats under the hood..

anyone?

cheers

The Death by Audio Fuzz War is pretty cool and highly variable tone fuzz. Gets a nice scooped big muff all the way through Maestro fuzz tone and shin ei screaming fuzz type sounds. The tone varies but the fuzz is all out all the time.

I have a few pics of the top and bottom of the board as well as some shots with the board held up to a light so you can see the traces through the board.
I was going to trace this but I don't have the time right now.
If you want to trace from these pics let me...

I have one but my camera is too shitty to take a good close up.

Here's the best I can do or now:

I has 4 2n5457.

Anybody want me to read them a story?
