Watch the Hot Shot online guitar lesson by Jeff McErlain from 50 Blues Guitar Licks You MUST Know
What is that cool effect on my guitar? Well it is a rotating speaker cabinet favored by B3 players called a Leslie. It takes advantage of the Doppler effect, the speaker spins around at either a fast or slow speed producing that cool warble. Famous songs to use one, Lucy In The Sky With Diamonds, Badge and Angel by Hendrix to name a few. Don't own a Leslie? Well get a chorus pedal and turn both the depth and rate up and you have a great imitation.
