I have been playing electric guitar for 2 years and my friend invited me to join his band. The band is just for recreation they do not intend to perform professionally. The problem I have is:

I have a Multi-effects (BOSS ME-80), and we rent small studios for a few hours of fun. The problem is one of the studios has a Marshall amp, the other has a Fender. We have no way use just one of them.

Should I set use Preamp in my multi-effects to use with this amps or not?


More info if you need:
- I have a Epiphone Custom Pro and a Roland Cube-40 at home
- We play Led, Ozzy, Slipknot, Sepultura, Godsmack, Alice in Chains...
If those amps have FX returns then you can just plug straight into that and use your preamp.
