which tremolo pedal has the most over the top machine gun sound? preferably one that works with large amounts of distortion.
If you are talking about Hendrix then I think it's a Uni-Vibe.
Not referring to Hendrix, but a tremolo with both a very high speed, depth, and square waveform
Ohhh alright. Beats me then?
dunno about Tremelo but Tom Morello uses a Delay pedal at a very short repeat setting and taps the strings with his hand (for more info watch the guitar world lessons with tom morello on youtube)
