I have over 350 review videos in Guitar Interactive Magazine - which is a free mag every month delivered to your inbox (subscribe for free) . http://guitarinteractivemagazine.com - a lot of the video reviews are also shared on YouTube: https://www.youtube.com/user/iguitarmag
My own YouTube channel, I had planned to start working on but life has a habit of getting in the way. You can find it at http://www.YouTube.com/DanVeallBassist and I would really appreciate some subs.
For those who like a tech read, I write every month for Bass Player Magazine in my own column called The Last Note.
Anyone wanting video demos, voice overs or reviews recorded, well I can do that too and I'm freelance and well cheap inquire within, as they say.
