Interested if you gigging ( when it returns ) guys always have a back up amp ?    My only and current rig is new and I don’t know if when I get back to gigging what to have as a backup in case of issues arising  My current need is 300 to 400w into a single 8ohm cab up to medium sized venues etc  Or have no spare amp and just have a di pedal in my bag  Ideas please .. if suggesting amps keep the cost down please to around £300
