Yep, it has pads for SMD clipping diodes but none are installed. This one uses a TL074 and apparently has a slightly different Tone switch arrangement than the original.
What's on the workbench?

Someone said something loooong time ago... I quote "I have the schematic now.... So there is a chance. 
".
Well... won't hurt to ask again.

That's... Weird. The original didn't have a tone switch, not even internally. Second version had clipping and tone switches internally. I think the second one also had 2 or 3 pairs of SMD LEDs (definitely LEDs just unsure how many) for clipping, other mode was no diodes. Jesus Christ JPTR is changing his pedals without even writing notes on them what changed.
EDIT: found the gut shot I took of mine. 2 germanium diodes and a clear red LED per side in the OG. Second version was 3 SMD LEDs per side with a dip switch to bypass them.

I see their QC is still shit... or they are lagging behind with the description updates.

Oh, please say you're sharing that schematic trace soon. I'm curious how they're accomplishing all that in that enclosure size and price. After watching a demo of one, I'm impressed. Curious how it's approached - besides the 386 mentioned in the ad.

Maybe it's not necessary, but if I'm selling a distortion pedal for $200 I'd be making sure that I had excellent solder flow and coverage. They're already using bigger high voltage caps where they're not necessary for mojo, so doing a little more pleasing soldering job should be included.

Those 50v Mallory axial caps, obviously. What reason are they in there other than for someone to open it and think it looks cool? They could have used 25v film caps and had it still be safe for someone to run at 18v. They could have made the board smaller with a potentially quieter noise floor as well. Not to mention those caps are more expensive than your average film capacitor.

If I were them I’d be plugging the *hell* out of the 3-way tone toggle, I haven’t seen it before in a pedal design and think it’s genuinely novel and a big selling point of the current version, and it’s also *super* useful - the high-pass filter mode lets you get kind of the aggressive tone-bypass Muff sound, but you can tighten up the bass to get a super useful angry sound, it’s my favorite of the three modes.
(Although I guess writing new ad-copy might be tricky because you can’t say “switch between Big Muff and Rat Tone Controls!” anymore. There any other historical distortion pedal that only had an HPF tone control they could name-drop?)
The current version is SMD, which was for sure done for cost (a TL074 and zero diodes is like, what, a tenth the cost of two OPA2134s and some broken germaniums?), but was also maybe done for build quality and consistency; seems JPTR FX’s gutshots and builds get as much flack as DBA’s?

What can I say? I'm disturbed! I'm depressed! I'm inadequate! I got it all!
Brian at MBP got me going on top soldering boards for a while. Over time I got tired of it and it was twice as much flux that I never cleaned off...I mean that I worked really hard at...
I would never dissuade (hey spell check thinks its a word) anyone from using this approach (especially the are-you-experienced amongst us) because in the time that I did that I NEVER had soldering errors. I chalk up getting two Aion BlueShifts to work without breaking a sweat as proof.

I didn’t know too soldering was a thing. I’ve been doing it because I’m just lazy. Good to know.
I'm Projecting this may interest the Members!
