Independent shopping perspective
The Korena take
Friedman’s BE-BB is a two-channel tube preamp module designed by Dave Friedman. Two 12AX7 preamp tubes power its BE and BB channels, with gain, volume, and three-band EQ on each. The BB channel adds a three-way bright switch and a two-way mid-boost toggle for further clean shaping. It is built to move between clean and boosted lead sounds, while the BE channel covers a vintage British-like voice through more aggressive distortion.
Strong match
Who this is for
- Moving between clean, boosted lead, and more aggressive distortion sounds with two tube-powered channels.
- Refining BB-channel cleans with its bright switch and mid-boost toggle.
