AUDIO AMP CO Deluxe Reverb


The BF Deluxe Reverb in its classic form is for many guitar players the »desert island« amp and one of the best circuit designs ever, offering two slightly different channels, one with reverb and tremolo.

Many things regarding the circuit and the layout can be improved; a lot of different »tone« voicing can be done to offer the player a more flexible amp, with more possibilities of tone shaping. For those you are fine with just two channels, which are switchable via an A/B-Box, if requested, offering even more flexibility.
