Your PRESENCE knob isn't as innocent as it seems....

In this video I investigate the influence of presence on your Marhall or Fender Amp. I realize I have vastly underestimated it's influence. Treaked right it can really sound like fundamentally different amps! I'm using a 2021 Marshall Studio Vintage SV20H and a 2021 Fender Telecaster Custom Shop 1960 Relic!
