hey there forum,

I was wondering how to do a tremelo fast or any tips on how to do them. please answer. But not with an amplifier, if you do it manually with your fingers, or picking very fast.

Start off slowly and work up speed would be the obvious answer. Also, I find it helps if I rest my hand on the bridge during them.

Tremolo picking is done exactly the same way as alternate picking. Start out slow and build up to speed, remember to use a metronome! I like to use the intro to "The Bitter End" by Insomnium to practice tremolo picking because it the note changes every 4 pickstrokes, so if you use 16th notes, you're changing note on the beat which makes it easy to keep track of speed. It also involves changing strings which is something a lot of people have trouble with when tremolo picking. Here's the tab if you want to use it:

Speed is a by-product of shut the fuck up.
