how do you get the effect of holding the tremolo arm and strumming without a tremolo?
can you get it in a pedal or something?
Not super easily. I mean, it's nearly impossible to do with open chords without a trem. Maybe a vibe pedal with the mix set pure wet?

Money beats soul...every time.

Money...beats soul...every...goddamn...time.
The BOSS ME-50 has an effect on the expression pedal that sort of mimics a tremolo. The further you push down on the pedal, it goes down in pitch, all the way to an octave.

As for the rest, I didn't really understand the question. Mind giving it in more detail?
