Beamer Dual Pentode Preamplifier


For engineers and producers who want to pack the maximum tonal flexibility into a single unit, Beamer is a God-sent solution!
With two amazing, yet different tube channels, this preamp will excel in any recording situation!

Channel 1 gives Berliner’s stunning detailed sweetness, whereas the Creamer side, thanks to it’s feedback free gain stage, yields the maximum harmonic coloration, without ever sounding dirty or fuzzy.
