Trident Audio Developments S-20 by countrymetalguy
This is a great preamp that I have used for years. I own 3 s20 units and they excel at most anything you throw at it from drums to guitars. The hi pass filter is really smooth and the A/B MIC Input feature is cool for comparing mics. I own lots of preamps like api,SSL and a Harrison console and these preamps hang with that level of gear. Many people shame this pre saying it isn't like a vintage trident 80 series, and it's not. BUT, it is a no joke preamp that can be had on the used market for a fair price.
