EQD The Depths (gut shots)

[BassVD]

As requested by Ciaran Haslett, I took my EQD The Depths apart and shot some pics. I started taking pics with my gf's DSLR, but unfortunately I can't work with that thing, haha. So I took most of the pics with my smartphone (quality is sufficient, I think).
There is one pic I edited with text, these are the values of components I couldn't get a clear shot of.
All pot values should be clear in the pics. The Rate knob is a dual B100K pot.
I hope they are good enough, if not, let me know as soon as possible: I'd rather leave it not unboxed for a long time :-)
So be quick with those questions or requests for more pics!

Good luck on tracing/decoding this one, guys. I think it's going to be a tough job :-)

[Ciaran Haslett]

Magic!  Thanks very much lad.  I'll get on it right away.

If I've any questions I'll try to ask as quick as I can

Massive thanks

This is gonna be a good one

[Travis]

Thanks BassVD and Ciaran, looking forward to the progress :)

[Ciaran Haslett]

Nearly there....

Can you get some clear shots of whats under each pot from the solder side?  Having trouble following some traces under them.  Fair idea whats going on but just want to confirm,

I'm pretty sure theres traces hidden under the ICs too. Can you remove them from their socket and get pics?  Or even draw what you see there and take a pic of it?

Again...thanks a lot man!

I want to keep an eye on this thread :) You guys are heroes.
Am looking for a Vibe pedal build. Settled on the madbean/Roger Mayer until this came along.. Excited how this is going to work out!

[BassVD]

@Ciaran: Will do it this afternoon! I'll put the pics in the same folder and I'll post an update once they are online. :) The only problem is the dual pot, I can't see what's underneath there, as I can't bend the legs...

Ciaran you're a mad man. I can't believe you seem to get 90% of it that fast. Seriously amazing work.

Can't wait for this one.

[BassVD]

Seems like you've been quite busy tracing already! :-)

Unfortunately, I don't have a meter with continuity check. If there's another, easy way to check it, let me know.

I've uploaded some more pics to my dropbox folder, just click the link in the first post. Hope the photos are good enough to help you out. But I don't think you can clearly see what's underneath the IC's, the sockets are way too fat. And I can't even see it with my own eyes. The same goes for the dual gang pot. I tried to bend the legs a bit and I could snap some shots, but what you see on the pics is what I could see. Nothing more. :(

I have no experience in tracing PCB's, so if there's anything I can still do, just let me know.

[Ciaran Haslett]

Haha cheers Zach!  I've been gassing for one of these for a while so when Bass VD offered to help I just couldn't resist!

Does your meter read resistance?  Set it to its lowest setting and probe like I said above.  A confirmed trace will read 0 ohm.  If the 2 points are not connected...it will read a very high resistance /error/ open/ OL whatever depending on your meter.

I'm at a city Christmas Light Switch on event now so I won't be able to get back to you until later tonight/tomorrow.  I'll have a look at those pics then too.

Cheers yet again lad!

[Ciaran Haslett]

Hey man.  Those new photos you got are great.  Nearly sure they answer most of my questions.  With any luck I'll have a schematic tonight with a view to breadboarding over the weekend.

I'll keep you all updated

[BassVD]

Great! If you still want me to check anything, just tell me! :-)

[Ciaran Haslett]

Working all weekend again but...

Update...signal path is done!  Working on the LFO now

[Ciaran Haslett]

Schematic now verified.

Trace


Schematic.  Hi Res here

[rocket88]

looks great so far. once you get it verified i'll give layout a whirl, that is unless alex beats me. haha. i'm sure he will since i'm coming up on finals after thanksgiving.

[Alex]

That will make it easier for me!
To be fair, we could try something different this time: we can submit the layouts here and use the one Ciaran prefers with all our names on it. Something different than usual.
By the way: great job Ciaran (and BassVD)!
Could I get a better resolution schematic?

[Ciaran Haslett]

Haha!  I wouldn't want to offend but sounds fun too lol.

I'll send you both a hi res version tonight when I get back to my computer.  I'm 100% on the Power and Signal paths.  It's the LFO i'm iffy on.  I'm pretty sure the trace matches the pics but I've never seen one quite like this so I'll BB it as soon as I can to confirm.

Cheers lads

[Ciaran Haslett]

I messed up the LFO.  I'll redraw and send it on later
