Understand the frequency range of the instruments in your band. Look for the frequency range where you are not competing with a lot of instruments and eq your rig accordingly.
P.S. If it sounds too trebly and honky in your bedroom.. It's probably gonna sound awesome in a band setting. Lol!
This, I've been playing for a while now, but I'm not really that good. And recently, nag search din ako ng topics regarding cutting through the mix, and narealize ko tong stuff na to. I mean it really makes sense, if you're going to provide what someone from the band already provides, then di ka nga maririnig.
RE: multifx sa IMO:
1. For solos don't use too much gain, as in swabeng crunch lang.
2. Boost is nice, pero I think it boils down pa rin sa EQ mo. haha
3. Wah! if my wah ka, may certain angle dun na for sure lulutang ka. Easiest way to cut through lol.
