hey... that's my lesson :)

It should work on acoustic too. It's just a matter of building up your finger strength. Pluck the first note, then pull down with your finger and it should sound the second note.

Just keep in mind that this kinda stuff isn't meant to be learned overnight.
It takes hours of practice.... then ya need to rest a coupla days... then spend another coupla hours at it....

Just be patient... you'll get it.
