Word. Found this site in my stumbles.
www.jazzeducationdatabase.com
Has some pretty awesome transcripions. Ron Carter, Percy Heath, larry grenadier (one of my favs) ect..And they're readable, and somewhat accurate.
I still reccomend getting the albums they are from and learning from that, but hey you wanna learn to walk a bassline like a pro, take a look at Grenadiers transcription. Guy lands on the b7 on the downbeat of a chord. Takes balls to do that haha.
But yeah check it out. im not affiliated with the site at all but i do enjoy it.
