Really an academic question but the other day, I was asked to tune down a semi tone for a section of a song. I was using 5er so potentially a semitone down from a low B. I’ve modified what I play so it’s fine but there was a wee bit of discussion about pedals etc and I was wondering if there is a pedal that can handle down tuning low notes? Played about with detuning on the Helix briefly and it was surprisingly good in the higher register but shit as it got lower!
