hey guys, i have my main rythm sound set up exactly how i like it, with just enough gain. but for lead work, that sound is a tinyyyyy bit below par, sustain wise. what am i looking for? a clean boost? a sustainer? a treble booster? HELP ME!

digitech main squeeze. "hit a note come back tomorrow" fairly literally

EDIT plus you get a tone set up so you can have a party with that too
An overdrive or clean boost would add gain and sustain, and you could try throwing in some reverb.
