This is one of my favorite circuits. I actually prefer it over most of the Ge treble boosters I've tried over the years. I have built a handful up for family and friends but not with this layout. Next time I do so, I'll try this one out. From a glance everything looks good.
I miss my JAX Fuzz/Wah...FUZZ II is a wall of bliss! Nice to see a schematic. I bought that pedal in 1984 during the " Analog old junk, new digital is king" era. Bought so many pedals for $15-$20 at the ironically 'vintage guitar' stores in Hollywood. The JAX I dug out of a catchall wire mesh trashcan near the exit for $5.
Thanks for posting this one! I built it not knowing anything about Treble Boosters...this is pretty awesome. Now I'm going down the rabbit hole and looking to build a few others.
Can anyone verify - is the "Range" on this one supposed to work in reverse? It seems like when I turn it "down" it gets heavier/more distorted but when I turn it "up" it gets quieter. I thought about moving to a 500Kc or flipping the wiring but not sure if I made an error (or if this was expected behavior).
Just a detail that I thought I'd offer as a useful mod for this simple but very nice circuit. Adding an input control is easy and in some applications necessary. I think the MKII has one actually. Use either a 50k or 100k linear pot. Connect board in to lugs 2 & 3, and switch in to lug 1. Allows you to place the boost somewhere other than first in line on your signal chain.

ReplyDeletethank you for the layout. you can call it verified ( my 2n2222 flat side facing right ) and i used B2k pot instead of the B1K.
ReplyDeleteSounds great.
Thumbs up! I'll tag it right away.
DeleteYup. Just built it tonight. Perfect. Thank you.
ReplyDeleteCool pedal!

ReplyDeleteJust remade this because I thought I should do it neater - it's one of my favourite pedals.
