VFE Pedals Merman

Another great overdrive from VFE Pedals based on the Klon Centaur.
You can find schematic and info on their website here.

  1. Seeing as how I am a klon(e) junkie ;) I'll have to build this one. Looks like a nice alternative with some unique features. And with six control pots, infinitely tweakable!

  2. Thanks for the layouts for these VFE pedals. They look like a classy company. What size are the small pots on these pedals? 9mm?

    2. The small, 9mm pots have the following part number - RV09AF-40-20K-value. I started hand painting the notches with a silver paint pen around the end of 2014.

  5. Verified! Sounds quite different to my Klon but in a nice way. Very tweakable for sounds. Cheers Alex.

  6. I noticed on the schematic there is a 5k attack pot as well?

    1. Ah nevermind... I see it is a trimpot I suppose for the level to tame say humbuckers?

    2. Ah! attack is the other half of the drive dual gang pot in a KLON.
      Interesting how VFE split that up.

  7. I have built this and it's the first time I have used a charge pump. I get a constant high-pitched whine which seems to very common, won't go away. I have good lead dressing, shielded input cable, tried battery, put a buffered pedal in front, tried ICL7660S and MAX1044. No change at any of these changes, The last thing I can think of is wait for the TC7662B ic in the post and see if that fixes it. Anyone have the same issues and how did you fix it?
