Which speakers to get there?
Ha! Which era?
First record: Marshall 800 into a GB loaded 4x12 … but by the end you could pretty much dial up their tone with a Line6 Pod direct 
Which Era? So I said “classic” but do respect that this isn’t specific enough.
So green berets then, I guess.
But I must know, does the Invader 50 replicate close enough?
Yes, I think it does … especially if you would rather your speakers remain tight at all volume levels.
