I think this is pretty interesting.
The audio sample here is played with a Sadowsky Jazz (pickups centered) with tone control 50% and EQ dials all the way counterclockwise (off). Sample is played into looper so the exact same clip is repeated. Please use quality earphones, not Apple or Android ear buds or cheap computer speakers.
Clip 1: Sadowsky into passive Rapco DBBLOX. This is a small, cheap passive DI box.
Clip 2: Sadowsky into Lightning Boy TI Box (passive box) with phase switch in out position
Clip 3: Sadowsky into Lighting Boy TI Box (passive box) with phase switch pressed in
Clip 5: Sadowsky into active RNDI powered by 48 volt phantom power
What do you think?
Remember, the DBBLOX and Lighting Boy TI Box are totally passive and require no power.

Ti Box sounds pretty good. THe RNDI is smoother. both in the initial attack on the front of the note and in the upper registers. Phase switch should make no difference what so ever but the clip ewith the phase switch in sounded a little bigger in the lows maybe? not sure.
What I need help understanding with the TI Box is with the Impedance matching. I watching the yT clip you posted when you said you were getting one of these and it talked about how impedance matching works with old school mic preamps etc, and that this box would thicken tone using that principal. If you have pedals between your bass and the TI box, does that mean the impedance could be different going into the box and therefore it can't thicken your tone as outlined?
