if...you forget that Sheehan ever existed, you realize that this guy has great talent and an awesome technique
...without effects unlike Sheenan's who has more Bradshaw built pedal boards than I can care to mention...
sadly I have no idea who Talas was, sorry but to me his sound was too processed and it almost sounded like a food mixer, specially when he used that cordless drill fitted with a pick.
People tend to forget that they can do this themselves as well. It just takes a bit of practice! Lock yourself up for a year and see what happens. you'll be amazed.
I don't know why, but the above scentence really annoys me, Capt! Nowadays BS has some cool stuff, sure, but remember he was in Talas way back and played his P straight into an amp every night, and in case you didn't really follow Talas in the 80's I can assure you he really can play, it's not the effects.
