Hello all, This is my first post here, but my second booster. It is intended to be used to return unity gain to a passive mixer (2 ch. pot 250k R100k).
I built a LPB1 that does not work as expected, cause is not boosting the mixer if I use it in the output (mix), and it is killing my strat highs (SSL-5 pup) if I use it in front in one channel.
I decide to check the V2 of this one and I have it in a breadboard using a 2N2222A that I thing is working OK: it boosts, but now I'm losing some bottom end when used strat > Mixer Ch1 dry / Mixer ch2 delay 100% wet > booster V2 > amp (the setup is more complex than that, but that's the idea). Also, I have the bottom end loss if I set up Strat > boost > mixer ch1: Boosted dry signal / ch2: Delay 100% wet > amp. I don't really know if the cut is because the breadboard, as I also have a lot of noise that I still need to track, or if it can be solved by changing the value of some component.
Of course, no amp equalization can fix this, so, Does anybody can recommend a change in the booster, to recover that low frequencies?
