I have to be honest here guys, I am getting a kick out of reading the last few pages of people trying to decide between a Finally or a Neptunium and the information being shared that is informing their decision on which to get. I own both so just know I’m not trying to cause trouble with my smartass comments, only trying to be helpful. These pedals serve very different purposes, they are both amazing and none of them are “hype”. For those of you that believe a noble or neptunium is hype, that simply because you don’t have a clue what you’re doing or how these different pedals work.
DI- refers to hardware that converts your unbalanced bass signal into a balanced signal to be sent to a mixing console. That dude that was unhappy about the pedals not having an adjustable HPF will be happy to learn that adjustable HPF are great for managing your stage gear to remove low end mud, but the purpose of a DI, which is to send your signal to sound guy running the mixing console is probably only concern with having to deal frequencies in the lower register, which is what the HPF’s on these pedal are specifically designed to do in helping the sound guys out.
If you play a show, the sound guys will be very happy with you using the filter switch on these pedals.
Neptunium- What does it actually does or the reason you should get this pedal. This thing is awesome and introducing harmonic distortion through its tube-based circuitry, essentially making your sound fuller, warmer with a slightly smooth, compressed character. It achieves this boost of warmth by adding "tube saturation" to your signal, which can be particularly beneficial for recording or live situations where you want a more polished bass tone. It will also change the way playing you bass feels and how playing feels to your fingers.
How a Neptunium affects your bass tone:
Warmth and Smoothness:
The main effect is a noticeable increase in low-midrange frequencies, resulting in a warmer, rounder tone compared to a completely clean signal.
Harmonic Enhancement: By introducing slight tube distortion, it adds natural-sounding harmonics, which can make your bass sound fuller and more complex.
Compression-like Effect:
Due to the tube's inherent compression characteristics, this can assist in smoothing out your playing dynamics, giving a more consistent level of volume.
Vintage Character:
This pedal can help achieve a classic, "old-school" tone reminiscent of vintage tube amplifiers.
Adding volume when playing with others absolutely has it limits.
When people say these pedals fill the room, it because they are literally filling out the sonics spaces and filling the room, while not increasing the volume, just the perceived loudness of your signal. This pedal can make your bass sound absolutely huge while still fitting in the mix.
Finally V3
How a Finally V3 affects your bass tone:
Does the same stuff listed above, kinda, with less harmonic adjustment because of the different eq/filter, and most of all,
because surprise…
it’s an Overdrive pedal

And what a marvelous pedal it is.
To be fair in my comments, perhaps the dude wanting an adjustable HPF is very much correct because it really depends on what you're using it for and what your setup is. I would say that in an off beat way if you want a noble or neptunium with more filter adjustments, then something like a Darkglass harmonic booster would be in order as it’s a preamp in the same ballpark with more filters, doing a similar thing a very different way.
I hope this information reduces the amount of unicorns running around and is helpful with folks choosing their next Sushi pedal. A far as I’m concern all the Sushi pedal are top notch!
