Congrats!!!!! looks super clean, HNAD!! rectos are so killer.
everyone's settings are going to vary based on guitar/pickups, boost, cab/speakers, etc but the good news is that they are generally pretty easy amps to make sound good. dont go overboard with the bass and gain bc there is a ton of both haha. treble interplays with the gain a lot too. maybe if you have a loop pedal try looping a riff and then tweaking knobs so you can hear what they are doing in real time.
