Thanks all for your thoughtful and helpful advice. Satchmodog’s distortion suggestion seems to come closest to getting what I want, but I’m not quite there yet. In the best YouTube tutorial I’ve seen for this song, the instructor said he ‘preamped.’ Pardon my ignorance, but what exactly is meant by ...

I’ve tried to play this song on my Orange 20RT but am not satisfied with the sound. On the dirty channel, it sounds too mushy and not dirty enough on the clean channel, as the amp won’t permit the addition of gain. I don’t have a pedal, so what’s the best way to dial in a preamp sound for this song?...
