I went for it! The Le Bass just arrived today. I ordered it from
Sweetwater-great service

! Had a good hour session with it this evening and I am very happy so far. I am blown away with how transparent this pre-amp is. Of course it adds tube gain, but the tone of my P Bass is ever present in all modes and at all levels of gain. Till now I have tried the EHX Battalion, EQD Acapulco Gold, EQD Speaker Cranker, Behringer BDI21, and Catalinbread F56. The Le Bass was what I was searching for all along
I was surprised at the amount of gain I could achieve using Channel A. Now don't get me wrong, there is clear increase in overdrive when you switch to Channel B, but Channel A can achieve some sag and bloom when you dig in. Channel A is a great clean tone and if you cut the bass and treble there is plenty of mid range on tap. If you are accustomed to passive EQs a-la Fender or the Hartke LH, channel A is very intuitive. In face, Channel A sounds like the pre-amp in the LH with a smidgen more of gain. The other major surprise was how musical the active eq in Channel B sounds. For reference I have an EWS Bass Mid Control, which is a parametric mid eq. This pedal makes my P-bass sound like an active instrument whereas the Channel B Mid Sweep keeps the passive nuances of my bass even when the mids are dialed up a bit. Very musical EQ section.
Channel A alone, channel B alone, and both fusion modes offer many usable tones as I could not make this pedal sound bad! If you treat the eq in Channel A like an active EQ and set the controls at noon, your tone will be very scooped. I do not enjoy a scooped tone, so this the only "bad" tone I hear (very subjective). The fusion/blend control is just icing on the cake!
I hope to use this in a band setting this weekend and If I do I'll report back

. The Le Bass just replaced all my pedals! I am still in the honeymoon phase, so we will see how the romance holds up.
