Stam Audio SA-3A by IzzyRock
I've tried the SA-3A on a mix today and I was absolutely blown away by its "sweetness".
I don't have the real thing in my studio, but since i'm mostly a plugin guy I've always used the Waves counterpart for electric and acoustic guitars.
I already started the mix without the SA3A but after I received it I HAD to try it on the acoustics and it just sounded 5 times better. The low end now was sweeter, and even though I liked a lot the plugin, I never realized how "hard" and thin the low end was sounding with the Waves compressor.
For me, the "word" for this piece of gear is SWEET.
I encourage you to get this amazing little thing and put some sugar flavor in your guitars.
