I just received my George L's cable, a gift from a friend in Canada. Compared my old cable (it is of good quality day and night: the bass became more attack, the sound is less muddy. The treble and mid are dtach more Arian, more clean.
I play with a Telecaster up with 3 Seymour Duncan Vintage Rail (fawn Start), a Fender Hot Rod Deluxe. I'm selling this amp that I find too "slamming" in the clear, but with this cable, I wonder if I will not give him a chance deuxime.

My only concern: is there a distributor in France?

My advice: before you change the amp, change your cable!
