Be honest - how many of these are you playing on guitar?
Very few, along with some riffs/licks from a few others, but not the whole way through. Of these, I only know how to play two start to finish:
Susie Q: The first song I learned how to play completely through
Voodoo Child - Slight Return: A major technical challenge that took about a year before I felt like I got it down to something recognizable. It's doable with the Zoomfire 30 modeling amp (Marshall stack settings) and Hendrix JH-1 wah pedal I've got.
Blues riffs/licks from: Catfish Blues, Hey Joe, While My Guitar Gently Weeps, House of the Rising Sun.
Right now, I'm working on Led Zep's Whole Lotta Love. It's straight up power chord play with two main chords, and there's a good youtube vid on how to do the zooming slide parts. The lead high-note riffs, short as they are, are probably the toughest part to master. In open tuning, I can add the single bass note to go along with the power chords.
