Maybe. But the "coming alive" is probably the bump in gain and compression you get from hitting your amp's input with a hotter signal. Once you go unity volume or lower you lose that.I do get to wondering now and then, even though I too use a boost for tone/sound. Well actually lately been using it more for boosting solos but anyway...
The idea that some folks use a boost to get better sound, and also want a “transparent” boost really jumped out at me the other day. It’s a well known thing that if one wanted to demo two pedals, if you have one of them slightly louder it almost always (if otherwise close) is heard as sounding better.
So I’m thinking “wait a second. Since the boost is claimed by some to be able to get “that sound” at lower volumes, but since it boosts the signal you are BACK UP to a higher volume...wouldn’t you get the same thing if you just upped the amp volume? Im going to try it today. I mean I know when I hit the boost the sound comes alive, but that is because I’m thinking I want lower volume. If I turn the volume down to unity...not so much coming alive sound. I’ll see if that is so.
