15 dbs of clean guitar friendly boost and a tasty buffer … This is your 'more' button. It really sounds like turning your amp up – the difference is that in addition to raising the level it also adds harmonic 'pre-distortion' content that improves the dynamics and clarity of your signal – and subtle EQ shaping just like your amp does as it gets louder… so your tone and even your other effects will benefit from the BPB in line – and of course the BJF buffer also repairs your clean tone from cable impedance imbalances…. Deluxify your drives ! If you've seen the very expensive BJFe Honey Bee and Baby Blue and Emerald Green 'Deluxes' …. this is whats in there besides the drive circuit —- the BPB is the buffer and the boost for those —- so put the BPB at the end of your dirt section and 'Deluxe' them all. 8-18v for more headroom and clarity if needed.
