How do I get the surf sound? I have a Fender Standard Strat (HECHO IN MEXICO), and a Fender 65W Princeton chorus amp. I'm using a heavy pick and the regular fender 9's on the strings.

I've tried palm muting fifths and that seems to be the best approach but I have no other idea how to get the surf sound other than "pick really fast"

I use Mediums Fender picks I like having just a little bit of bend for the tremolo picking and I just go as fast I can near the bridge I have found that this greatly increases my speed.

Oh yeah almost forgot turn any reverb all the way up it gives the surf sound to it.

Maybe leave the bass at 4 1/2 mid at
5 and treble at 7 and I agree about excessive
reverb.

dude, i had almost the same rig when i was younger, its great for surf. turn your reverb up, and play only single notes. a scale you can use that sounds great (dick dale used it) is: E, F, G#, A, B, C, Eb, E. try that out.

Use a lot of stacatto jabs, a clean toe, and lots of reverb.
