Watch the Uni-Vibes online guitar lesson by Jeff McErlain from Essentials: Blues Rock Grooves Vol. 1

Interestingly enough, I grew up listening to more Robin Trower than I did Jimi Hendrix for some reason. There are a lot of similarities between the two players, and Trower has taken a lot of heat for this, but if you really listen to them you'll see the similarities are really just on the surface. Robin Trower has his own sound and is actually a contemporary of Jimi's. His early career started with the band Procol Harum but he did not play on their famous song "A Whiter Shade of Pale." Trower's breakthrough record as a solo artist was Bridge of Sighs and this continues to be one of my favorite records. Using the classic rock set up of the Stratocaster tuned down a half step into a cranked Marshall, he also favored the uni-vibe pedal as a key element of his sound, so much so it's hard to hear a uni-vibe and not think of him. I can't recommend Bridge of Sighs enough if you're not familiar with it, it's an essential record that stands the test of time and still sounds fresh. I'm also a big fan of the late Jimmy Dewar on vocals, a power trio at its best!
