MXR M-103 Blue Box Fuzz Octave +C11MOD

Here it is a quick test of my "new" MXR M-103 Blue Box. I've bought it used and immediatly applied the C11 MOD, patching it with a smaller capacitor, having as a result a very open and wider sound, eliminating the 'volume drop' problem, and improving IMHO the overall sensitivity.
It's really a FUNNY pedal, more musical than useful, but really really enjoyable!
Blue Box loves neck pickups, better if single coil, and hates chords! :D

@Livitation3 Hi! The C11 capacitor originally should be 4,7nF, mine was a 10nF and it was pretty unusable.

Actually is working with a 2,2nF in the sample you heard and IMHO is far better!
