Here is what hapened.
The weaether was very hot in Paris a few days ago (and now it's raining...

While trying to increase speed on this slidy part, my hands were kind o' sweaty (the heavy weather did not help) and I ended cutting my forefinger on the E string !
The wound is small but very stingy and it's been two days i've been looking at my Jem 7vwh without being able to train because my hand is unconfortable.
Such a shame, i was at the same time working on a Juice cover i hope to post very soon.
Has it ever happened to you to cut a finger on a string ?
12 years of playing and it's my first time.
