Hi I am Mike a pro guitarist in Memphis.Have you ever listened to John Petrucci,Eric Johnson,Dimebag Darrell,and listened to them soloing very fast solos.What they are playing is monster riffs.You have to relax picking hand but challenge your picking hand.And your fretting hand plays scale patterns that lock together,if done right you can blaze up and down the fretboard playing blazing solos.But you have to play slow first and build up speed over time.Playong monster riffs is not as hard as it sounds
