have almost been there, just haven't had the time. Let me see if I can get it done today or this week as I got some things out of way.

Almost done. Just need to double-check everything and have a layout which includes value and can put this to bed this week! "G" in red indicate all of the pads/nodes which are grounds.

Still working on it. Have been tied up, so no time for this. Funny, I have a 4th head available. ALL 3 of the original heads I had were all black PCBs. However, the 4th head has GREEN PCBs!! Not sure why this one was green, maybe early head as the revision level are all the same at V03, but...

No, that's not it!! I measures in CAD the approximate location of the centerline of all of the pots and switches and differences between them. Basically, the distance between pots is .75" and up front where there is .625 (5/8") between the gain pot and switches (in red). If we look where the...

I de-populated the bard, scanned the PCBs, and created the footprint and pads this weekend. Ran out of time to finish, but will this weekend. Here is where I left off.

Attached is the Output board for reference

Ok, I was able to to audit the schematic and PCB. I missed a couple short traces, now corrected in the attached. R33 is 22k as in the schematic, NOT 16.2k, now corrected in the attached. C21 I forgot to label, now corrected in the attached. I added descriptions for S1 and S2 on the PCB I...

Thanks Robert! Yeah, let me audit it versus the PCB this afternoon, which should be 100%! I'll let you know and mark up any changes needed on the schematic. I'll be doing the same to the amplifier and output boards this weekend, but need an SMD hot air workstation coming in Sat/Sun. So those...

We'll see. I sent contacted him in parallel in regard to the above PCB layout. If he didn't do it before, he could create a schematic from mine. Should be 100%. I have 3 of the mini heads (BE, SLO, and Bogner). Of the thee, I like the SLO the best and BE the least with the Bogner in the...

Posting this as it's a pedal with a Class D amp and FX loop. Would be nice to have a schematic created and see the difference between this and the BE-OD Deluxe and how to modify it to make it even better. There are 3 board: 1. The Main board (this one, which is the preamp (pedal). I think...

No, you guys aren't getting my fucking point... My point was that the D+ was not to vintage spec and I identified it and what the root-cause was and diode values incorrect. Once corrected...BOOM, sounds the way it should. Fast-forward to the current situation and this thread (if you can keep...

Thanks and understood. The unit I use and test with is a Peak Atlas DCA75 which does have a curve tracer function. Then I tested a myrid of RR-104 pedals and then compared them to my original vintage 1978 and 1980 D+ pedals, they were all tested with my DCA75, so when I was seeing some RR-104s...

I just found this page which is VERY informative IF correct. It is only the diode portion and not transistor information but provides the values across all variations. I just question if they are in-deed confirmed and 100%?!? It suggests the following Vf's: 1N34A (0.21Vf) - Distortion+, Klon...

What are the specs Hfe and Vf of the diodes and transistors of the original early 80s pedal, so the tone is correct. I've seen some transistors suggested as direct replacements and had a 200-400 Hfe range, while other suggested at 600-800 and the originals SUGGESTED at the higher range...

Has anyone actually pulled and tested vintage components so we know 100% what the hell the actual readings are, say Hfe or Vf?!?? I found out this the hard way with the whole MXR RR-104 fiasco. They released a limited run of D+ pedals supposed to be 100% to Randy Rhoads original pedal spec and...

I like these MODs to keep it vintage, but give it a little more gain +46dB => +60dB

Thanks guys. I ended up used the Distortr and measure it out. It was something like .125" outboard and built it up over the weekend! installed perfectly and besides that, nice Bass Distortion pedal! I actually built it for reknown bass playin the Detroit are and friend of mine of 40 years...

I looked to see if there was another ZVEX pedal that was close. Sure enough, the "Distortr" has the pots in the exact same position it looks like! The pot needs to be moved over. In the Distortr, there are two, but the one that is similar to the Basstortr looks to be in the same Y position...

Appreciated, but the switch is not in the right spot!

Can you PLEASE post the drill template so I can finish this tomorrow/this weekend??
