Excellent sharing going on... I hope this thread will become a reference point for budding guitarists out there. Its most often the guitarist who is the LOUDEST and most OVER THE TOP.
I just remembered.
If possible. No. Actually, ALL THE TIME.
TUNE IN
SILENCE.
It is extremely amature, unprofessional, irritating to have guitar sounding off open strings and keyboards helping, or guitar & bass tuning up together. Its an instant turn off, for me at least.
Tune BEFORE going up.
Tune WHEN up there.
Oh yeah, intonate your guitar too... SoulJah has a point with vibrato + bending, but nothing much will help you if you are not intonated properly, especially bassists.
