I'm primarily a guitar player but I'm going to play bass for one of my favorite local bands. I recently bought a GK MB500 with a GK 410 cab. I have a Zoom G5 I use for my my guitar effects and distortion (and also amp modeling when I record). I would like to use this on my bass as well. Is this safe for the pedal, amp, and cab? Also I've heard of people using bass amps for guitar. Am I safe using the G5s amp modeling and running it into the bass amp essentially using it as a PA? Any other info about taking care of my gear would also be much appreciated.
