Although I listened to Satch a fair amount I never played legato in the way he did and it's been an interesting couple of weeks working on the technique, it's ok in most places but single string runs are difficult.
If it was easy I guess it wouldn't be worth doing :)
Enjoy and thanks for listening
And just for the geeks: Ibanez RG421, Boss Katana no other effects/pedals, $200 AUD Acoustic, Superior Drummer and Kontakt for bass.
Cheers!
