this i have no idea why some sound guys feel the need to make a band sound how they want, they should take in how the band sound and go from there make suggestions if needed, ive had sound men try and take a di straight from my basssaying they like a clean signal ( i use a big pedalboard) and then had one guy just help him self changing amp eq and pedal settings.
for me ir wont sound like they do in headphones but sending that to a foh will sound better than a harsh di and also the venues who will mic any guitar amp they see yet scream and run from putting one on a bass.
its also to be said ive seen people turn up and want to use the exact sound threy recorded with.....this 90%of the time wont work either
