lol. Eco picking took me two years – and I practice everyday. As with everything, play it with a metronome at an annoyingly slow BPM. NO! SLOWER!
Then practice at that speed longer than you want to. NO! LONGER! Bump it up two or three BPM the next day and repeat. Do it everyday for a half-hour. This process will make you want to eat your own eyeballs and shake babies. But after a month your eco picking will sound like cards in the spokes of a bike. Do kids even put cards in their spokes anymore? That’s a rhetorical question. I don’t give a shit. Point is – practice at slow speeds and you will see results!
Good luck!
Cheers!
