EP Booster (modded version) - very good sound - 105 th pedal built!

* Finished an EP Booster with an internal voltage doubler(you input 9V, and internally there is 18), and some other tweaks (extra tone cut pot and a boost pot + a three way bass switch).
A really great sounding variant!
You can even get some nice grit out of it maxed

The mod: Basically, you replace the 47nf input cap with a 3 way dpdt on off on, in the middle you put a 470 PF cap, on one side a 561 pf one, and on the other the stock 47n; You replace the 3k3 and 4k7 of the two 2n5457 transistors, with 1K and 1K. Perfect!

Youtube Samples:







Even better once I tweaked it a lil bit more!
