Here is a guitar lick in Drop D tuning down a half step. It is a pretty basic lick but I like the way it syncs with the drums. watch for the 16 notes and use right hand palm muting throughout. The drums are from the fantastic guitar app Ampkit and are used with permission. I have no affiliation with Ampkit but you can buy the app on the itunes store for half price this weekend. I just did and it sounds great. Questions, comments, complaints send me a message. You can follow me on twitter @jimifan. Cheers. Here is the guitar tab.
