Not loud enough? in Powercab Posted January 22, 2019 Just as an addendum to this thread - I tried all sorts of things to get it to be loud enough but in the end I was runnng everything maxed out all the time (using the regular Powercab, not the Plus version) - I was also getting some nasty clipping sounds that were ruining my experience. This is with a moderately loud rock covers band. The Powercab just wasn't loud enough so I ended up selling everything and getting a Kemper powerhead (600w) with a Matrix FR212 cab and I hardly ever have it above 10-15% volume. It's a real shame as the Helix/Powercab sounded great but for me it just couldn't cut it in a live band scenario.
