BOSS US have some very interesting goodies on their website. First, the excellent Paul Hanson is giving tone recipes every month. He basically shows you how to reproduce the guitar tone(s) of a famous song using a small set of BOSS pedals. It is really cool, click on the image to go to the index:
Secondly, Paul Hanson has been hosting a podcast (available here) for a few years now. There is a new edition more or less every two months and it usually features one guitarist or bassist. There is a lot to be learned, most of the interviewees are session musicians and I wish they would all stop reminding me that I should always practice with a metronome. Anyway, check it out!
