Have been in exactly the same situation Ricco, I'm used
to just being able to read the music and never look at
the instrument, then I've brought in my electric and suddenly
am fumbling all over on songs I know very well
As Jimmy said though, its just practice, I spent 3 years
struggling in a community symphony getting able to get
basic comfort on the DB, no reason to think the electric
is just gonna come for free
What I do is just take the electric to rehearsal and force
myself to use it. It'll come with time. Everyone likes the
change in sound anyway.
Good luck,
