If you're not, here's a fine introduction!
Rob and his associate—aka "The Captain"—typically throw themselves into gear-related "challenges" and film their trials, tribulations and drinking along the way. This particular challenge, which is from the summer of 2014, is called "How to Gig for Under £500—Gigging Guitar Rig Shopping Challenge!" ... and it's already surpassed the 1,000,000-views mark.
It certainly does address an important issue: How can you put together a worthwhile gigging rig (where you're able to be heard above the drummer, as they say in the clip) with a budget of £500, or about $650-ish?
Check out the results, and stay tuned for more vids by Rob and the Captain.
