hey! I’m considering a multi effects or small board for travel. There would be a back line amp. I use overdrive, boost, delay & reverb. Budget is $350 or less. I play roots stuff: country, rocks & blues. I’m considering a used FlyRig or T-Rex Magnus. I am concerned that with boards, anything other than a 3 prong power supply like Voodoo or Cioks has resulted in noise. Any suggestions or comments or experiences?
