I know I've said it before but this time I really have found a single amp good for harp and guitar. And it comes like that. No mods, speaker swaps, tube changes necessary.
When I heard liquidfire's tone through his 63 reissue Vibroverb, I knew this amp had potential. Youtube videos by harpsucker and multiple guitarists got my hopes up enough that I found one.
I am more than satisfied with the harp tone and guitar tone.
