I have a 50’s Gibson Discoverer with tremolo. 12” speaker. Ised it with a Samsamp GT-2 pedal for a long time as a practice amp. Probably would record well.
My little old Vypyr 15 sounds very convincing when miked. I could make it work on an album if I had to. It's got some beyond decent high gain stuff.
I paid a whopping $50 for it used off Craigslist.
I'm with this along with some of the vintage Gibson and Gibson Maestro circuits. There are great rock and blues tones there. The Les Paul amp GA-40 is killer. I have an old reverb echo deluxe that has smokin' tone when it works right, lol. Grey glass sylvanias. Great studio amp.
My best sounding amp is a JMP 2104 with the original black back speakers. I usually use a 2204 head with modern speakers because I'm so afraid of blowing up those old black backs, though.
