      I agree ! ... goes very well with humbuckers ( I played it with a MelodyMaker with one Burstbucker Pro on Bridge ) ... even like it more than my OCD ... verified and recommended for Marshall-type sounds.

      ... with a Strat I‘d recommend to put a booster in front ...

      thank you very much Alex !

  3. This is pretty much a slimmed down Purple Plexi. Looking forward to building it!

  4. I tried this as my first stripboard project. I've been skeptical in the past, but after giving it a shot I have to admit that it was pretty easy. I'll definitely be doing some more vero pedals.

    Thanks for all of the amazing layouts posted here!

  5. Hello
    I tested the editing and I have a big hiss, I wondered if the IC is a JRC386D?
    I tried a LM386 and the problem is still present.

    If I cut the link of the legs of the top of the IC I no longer have whistling but more distortion either ...............

  6. How do I get more treble from the tone pot?
    Thanks in advance.

  7. It definitely sounds a bit muddy with single coil pickups. I didn't have a B50k or A250k so I have to lower an A500k and a B100k - could that be the issue? I've heard that altering potentiometer values changes the sweep a bit.

  8. I had completed this build. All controls seem to work.
    However, I find the sound to be muddy and "flubby" in the low end.
    Is anybody else experiencing this or have tips to make it have more high end or presence?

  9. To echo others here I found this a bit muddy even with single coils. I messed around with a few values to make it brighter...

    Changed 22nf for 1nf (this cap appears to be 4n7 in Purple Plexi)
    Changed the 4k7 next to the 22nf for a 12k
    Changed the 4k7 next to the 330r for 56k

  10. hello captain,
    could you describe / explain what each of the three changes did to the sound ? ( brighter, more bass, overdrive, etc. ...)
    thank you. ... frank

    1. Just recently built this. Went by the layout first, and like many others say I found it a bit muddy/dark. I then tried the three changes suggested by captainpena.
      First changed the 22nf to 1nf. I found this to brighten the tone up a bit as well as increase the drive and overall volume.
      Second I swapped the 4k7 for a 12k. I found this to "tame" things a bit.
      Third I swapped the 4k7 for a 56k. I found this to tame things further and bring the overall volume back down.
      The middle position of the tone knob is now more like the full clockwise position from before the swaps. I prefer the swapped parts that captainpena suggested for sure.

    2. I should add that I used a A50k pot for the tone cuz thats all I had. Also I only had a A500k pot for the drive, so I put a 510k resistor from lug 1 to lug 3 to make a 250k.

  11. What does the green dot on the jumper under the IC mean?

    Thanks!

    1. It's a double link: two links soldered to that same spot, one of them going to ground (bottom row) and the other link goes to "2" of the IC.

  12. Hey! So I chose this for my first vero project and I'm a bit confused about the input and output. I get which lugs they go on the pots, but are they wired to the board or straight to the switch? Thanks

    1. They are wired to the "board in" and "board out" lugs on the 3pdt footswitch. Check out the Off Board Wiring section if ya havent already.

    2. Ah good that's what I did, not getting sound though, time to troubleshoot lol
