Any suggestions for pedals that do octaves and/or harmonizing notes (3rds, 5ths, etc)? Special Consideration: this would be used with a bass down-tuned to ADGC (WIP). Imo this would sound better than tuning up to ADGC and using octave down pedals. The low low notes bordering the range of human hearing just sound better when produced naturally rather than digitally. Plus I plan on using the low end more frequently than octaving up kinda deal, so I would rather not have to rely on a digital replication.
