could go both ways
yes, equipment does have a big effect on one's tone. lets face it, you couldnt play megadeth through a fender deluxe reverb and a tele. the type of pickups, body wood, and amp type have the most effect.
but, to say that the fingers have no effect on your tone is absolutely absurd. id say it even goes as far as 75/25 with the fingers being the most important. you put someone like david gilmour (pink floyd) who has an incredibly light touch on the instrument, and you have someone like SRV who was brutal to his guitar, and you have them play through the same equipment, they wont sound nearly the same
ive gone into guitar stores and had friends play the same equipment with the same axe and settings and they have sounded a great deal different.
also, gear doesnt have that big an effect either. sure, youre probably not going to sound like eric johnson with a squier tele and a solid state marshall practice amp, but then again you wouldnt sound like johnson if you were playing his exact equipment either. I play through a line 6 flextone iii with a carvin dc127 with a floyd and evolutions, and i have a tone that is unique to me. I sound the same through my current set up as i did with my old peice of **** solid state peavey amp (that weighs over 80 lbs, i hate heavy amps) with my pandora px4.
it is my opinion that it isnt the fingers, nor the equipment, but it is your technique and most importantly, your approach to the instrument. once again, you could have someone who has a very cerebral approach to the instrument and someone who is very aggressive musically and have them play the exact same thing, and it would sound different.
