Hey chuckd666,

Did you get this fixed?

My tapanator tremolo is doing the same distortion/overdrive when set to unity or higher volume.

Oops, don't know why this didn't come up in my search before posting:

DELETE MY POST IF POSSIBLE THANKS!

I finished a Tapanator with just the Tremolo and Phaser (Pretty awesome!), along with a tap tempo cave dweller, but I'm getting distortion/overdrive when I use the tremolo.

I set the tremolo to unity, so it's definitely not because it's driving my amp. (I set my amp clean to take pedals and let the pedals do the work haha)

Anybody else have the same issues?

I plugged it in last night and it is not making any delay sounds, just dry hahaha

I'm going to assume the pt2399 in there is dead... Worked pretty well a few days ago, but not no more. I had a bunch from Tayda and a random eBayer who caters to pedal builders. 10x for $6.##, but I'd say half of those were the most noisiest pt2399 I've heard.

Yeah, I just have a TL062 in there.

I'll wait for those pt2399 and change C10.

Thank you! Hoping to do a build report soon... haha

So! I changed the following according to your 2015 build report:

IC1: OPA2134
IC4: OPA275
18v Chargepump for Dirtbaby

It's a lot better now, but I think I still need to find a pt2399 that matches the tempo clock. I ordered some pt2399 from mammothelectronics.com They were almost $3 a pop! So I'm hoping they're tested and legitimate, but who knows, didn't bother to ask haha

I saw on your 2015 build report you used an IR9022 for IC3. Haven't been able to source one, but it looks like a TL022 or any dual op amp will do.

I'm still not liking the dirtbaby all that much, but I've read so many claiming it's a great pt2399, if not, the best. I'm assuming I messed mine up haha

I should also mention that this 2015 dirtbaby pcb is considered "defective" by madbean. He received a few pcbs from his mfg where the board thickness was too thin, so I just decided to buy it at the discounted price.

Anyway, we'll see what a TL022 and new pt2399 yields!

If all else fails, I'm going to stick a Deep Blue Delay in there!

Dude, you have been so helpful! I'll check the specs for those 5v regulators and ICs to see if everything can handle the 18v. Worst case, I can just put a chargepump dedicated to the Dirtbaby. I should have space!

When it's all said and done, I'll post gut shots and all! It's really mess though! Those RG174 cables are a hassle...

Oh, I see what you mean by back to back!

Thanks again, will post back in a few days! *high five*

Dude, thanks for the replies and suggestions, I appreciate it!

Oh, I forgot to mention I'm using Madbean's 2015 dirtbaby. I compared the schematic and they were almost identical with just a few resistors/caps in different parts of the PCB.

I should also mention that I only did the following mods:

C13: Nope
C12: Yup, to 150nf
R4: Yup, to 22k
R35: Yup, to 56k
R37: Yup, to 120k
C10: Nope
C3: Yup, 2u2 to standard elec with + leg going to R37
R38: Yup, jumper
A100k: Nope, kept 100kB

haha I guess I could try raising C12 too and lower C13 to compensate for the dark tone/noise "ratio"

Thanks for the suggestion on the 1n4148 back to back! Not sure which feedback lug the negative side goes to, but won't be hard to figure out!

The reverb I put in the pedal is a GGG reverb with a SHORT brick and it is lacking haha My V2 I had a Tenebrion Reverb with a MEDIUM brick, which sounded so good! I guess I'll finish this off and start a V4 hahaha

Thought I'd update my Dirtbaby Tap Tempo build. Sadly, it didn't work well. I wasn't able to find a good PT2399 chip that didn't have white noise and sync'd with the tap tempo lights. Must have tried like 25 of them...

Everything else worked though! The tap, modulation, everything! No lfo bleed either, but that might be because I used RG174 shielded wire on my INs and OUTs.

I did notice the Feedback control, at max, would feedback like crazy, but also increase the volume to unbearable decibels! Worst I've ever heard.

Am I completely out of options? Is it my circuit that's causing the PT2399 to sound terrible?

This was going to be my V3 of this Reverb + Delay, but V2 sounds a lot better

Awesome, thanks for the help! I appreciate it! Excited to build this!

Hey Boba7, thanks for paving the way! I'm about to tackle a Dirtbaby Tap Tempo with Guitarpcb.com's Tap tempo board.

I was curious about your C3 comment about the positive leg going to R38 (jumper)

Is this diagram how to wire it? (Attached picture)

Doesn't that mean R37 will not be connect to anything?

Please, let us know, thanks!

[(1) Project Name]

(1) Project Name
-Mad Bean Pork Barrel

(2) General description of the problem
-No Signal when engaged. Bypass Signal is good. I get a loud thud when I engage the 3pdt switch and get some microphonic thuds if I move the pcb around.

(3) Steps that you have taken to try to resolve the issue
-I've checked all my wiring
-I've re-soldered all joints to rule out cold joints
-I've tested several ICs for the TL062 and 4558
-I've bought my MN3007 and MN3101 from a known source, as I've purchased from them before for my first Pork Barrel build, which worked perfectly first try!
-I've double checked my resistor and capacitor values.

(4) List any substitutions you used for parts/values
-Instead of using the onboard LED grounds, I wired the + LED to the PCB and the - LED leg to the stomp switch, which would explain the thud when I engaged the 3PDT. That does not explain the no signal being passed. I did this only for LED2. LED1 I've omitted completely.
-I thought the pcb relies on the LED's being installed correctly, but according to the schematic, the LED's can technically be removed and the circuit should still work.

Not sure what other options I have and not sure why this time around it didn't work. I've built many many pedals, mostly from Veroboard, which, IMHO is harder than a manufactured PCB.

Any help is greatly appreciated! Any help!
