The description of the bass control almost seems like the behavior of the tight knob?
Low mids freq to upper mids.

Anyone build it?

I love the samples of the pedal.

Anyone trace it, correctly?

Disappointed... I guess I will have to get one of these to get it done. What a dick tease... All chubbed up and nowhere to stick it. :scratch:

Aye, the poster only ever made 1 post and never returned. :slap:
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

Let's give this a shot. I've got it for a few more days, so if anyone wants me to double check something, please let me know.

Big correctionss with R2, gain section and presence section. Some minor additions in power filtering. 33k resistors confirmed in the bass section.

First off, I'm new here and just want to thank everyone for all the great work done here!
Just saw this and have been wanting to build this for a while. Thanks for posting! The final picture there seems to be cut off on the right hand side. Is there a way to repost it?

Much thanks!

Woops, sorry about that. The picture is actually cut. It is a 10k resistor to the volume pot. Same as the schem on page 3. Wish I was good at using a schem drawing program for clarity sake. Hoping someone will take my work to the next level by drawing up a proper schem. Also, the original owner will be snagging it by the weekend, so if anyone has anything they think I should double check, please ask!

Verify the whole thing. It is largely my fault that most of this schematic is guesswork. I simply drew the parts to create a device that worked. My apologies. Thanks for verifying the 33k :)

Great! Thanks again for all the work.
It's crazy to me that there are no Jfets in this...it sounds from the clips like such a tube overdrive that i thought it must certainly have those involved somewhere. I guess the leds make sense to give it some headroom on the clipping. Has anyone built this yet?

One last question, (maybe lol)...is C2 confirmed at 470pf?

Oh, and does anyone know what color the leds are? Not that it's super critical, just curious to see what was used

I cant confirm the caps as they are unlabeled and smt. Same with the LEDs. Resistors are confirmed as they are labeled.

I built the tagboard layout yesterday, but am having issues:

1. Low Volume. I can Max the Volume & Gain, and it's at the volume level I play in my Apt.
2. TIGHT Pot. CCW and my volume/bass increase. CW my volume decreases and treble increases.
3. The TRIM pot, when set half way or higher just sounds so bad... It's such a bad distortion sound haha Setting this all the way down seems to sound good, but I lose a lot of distortion.

I used:

Bat41 Diodes
3mm Red Leds (Diffused)
C1: 470pf
C2: 1uf film

I've taken my board under a light to spot any bridges and everything looks good. Went over my component placement, links, and cuts several times with long breaks in between. Going to go over them again today with a fresh pair of eyes haha

Unlikely that it works yet. wait till it is verified by multiple builders.

Hey guys, thanks from me for all your work. A little later to the game. Got this pedal when it first came out. I think there is some good tone out of it, but it's a 1-trick pony. I have no idea why this is even called an OD. It's a distortion pedal ONLY...which would be fine if you can adjust the amount of distortion, but really you can't and it's limited. Likewise, as psychodave indicated, I likewise would want a mid in the tonestack.

I do think this gets in the BE-100 arena of tone to a clean amp, but that's it. They probably retarded it, else people would not need the amp. I'm a little pissed from that standpoint, but because the general tone is there, here is what I would like and willing to do...

I have one of these pedals. I plan to depopulate the entire boards and trace it and build clone PCB(s) to ensure the design is 100% and a baseline and will post it here. I would then like to generate a schematic based on this actual baseline design and identify the areas of improvement, then re-design it as Rev.2 and build the fucker up the way it should be! Are you game? I hope so. I'll take the time to blueprint the baseline design and clone PCB(s) and will be looking for your time and support for the schematic and improvement ideas (as I'm busy as fuck, this will help distribute the workload).

Look for my portion in the near future and possibly this weekend (thou I have a couple events to do). In the end, I want a fully-functional BE-DIST pedal and put on my pedalboard.
