BJFE Blue and Black Berry Bass Overdrive 2023

Up for sale is a used BJFe Blue and Black Berry Bass Overdrive, it’s a one of one custom build (Siamese as Bjorn calls it) pedal. Here’s a bit more info from Bjorn:

“The custom Siamese is done see picture belowFirst in chain is Blueberry 
Tone/ Nature on Blueberry works just the same asB knob in this version Actually I had some 20 years ago only access to a limited selection of potentiometers basically two values 500K and 50K, two tapers linear and log, and so I had to come up with ways of using those to the maximum Later I could get more values and so Years ago when I needed reverse log I’d wire up a log pot backwards but now I have many values to choose from and can get precise on user interface so B knob does exactly that the original did only now bass increases clockwise I also added a treble control and if you put that fully CCW it is outof circuit; further I added a midboost/vintage mode switch This is because midswitch and treble control can be handyBlackberry is wired just like always About phase angle versus bypass both sides are 180 Degrees outof phase which becomes in phase when both sides are used at onceThose I know that have tried either of these models in parallel with dry have all said parallel did not add anything good but all have preferred series with either Blackberry or Blueberry.Stacking both sides can give heavy gain and under such circumstances parallel could possibly be good but hardly necessary imho
