The Pultec Sound

The sweetest thing about a Pultec is how you can alter the frequency spectrum in such a drastic and desirable way. I remember the first time I used one (on a Russ Taff record in the 1980s). I was floored by how I could add all the presence and brilliance I wanted without any sibilance or harshness.

How was that possible?

And I could grab as much warmth and fullness as I desired without the bottom end getting muddy or thick. Again, how does it do that?

The Retro Instruments 2A3 distinguishes itself by offering two channels in one unit and also adds a switchable subsonic filter (40Hz or 90Hz).
