4 from 5 sweet Big Muff tone

Enjoyed this kit, knocked 1 star off because the Pots arent PCB mounted, which I am used to.... so it makes for a lot of point to point wiring inside the case, which can be a pain.

Board is well laid out,- instructions could be a bit clearer on how to wire everything up...
I had to check a few different GuitarPCB kit instruction sets, to see how the 3dpdt switch is wired into the board..
The sound of this pedal is really sweet, lovely tone, sweet sustain, dense fuzz...no unwanted buzzing or howling.. tone control is a good wide sweep..
I have a Green Sovtek BIG Muff from years ago - and this one has a wider tonal range and has a denser fuzz..
I like the dual mode LED,
great kit overall - recommended
