You don't have to choose between a clean, transparent preamp and a "colorful" model with vintage character. Radial's PowerPre gives you both - and then Some!

This 100%-discrete preamp is loaded with a vintage-style Hammond broadcast transformer and a 3-position EQ that lets you pick either linear for classical recording, added air for enhanced voices, or extra beef for fattened up guitars or female vocal tracks. Plus, you get 70dB of gain! You won't believe how versatile the PowerPre is!
