I have the regular Small Trees which I have used alongside various DI boxes (EMO passive, Radial, RNDI) which always sounds fantastic. This DI model makes use of a fantastic transformer from Sowter (as used in some wondrous studio EQ and compressor units) for the DI output.
It runs on 12VAC 1000mA, though I'm told it can run on 500mA, though has a mA spike at startup hence the stated 1000mA. Mine plays well with a Strymon Puma R30 on a single output, no issues. Same with a Truteone CS6.
I've AB'd mine alongside a REDDI and preferred the Small Trees (similar feel without the mid hump), and similarly with the SLO MkIII (obviously it lacks the EQ, IR and some of the functionality) , it also compares most favourably against the Noble in my opinion (again when not in need of the EQ).
In general I feel it adds both weight and focus to the tone, whilst adding both warmth and some "sheen"/"gloss" to the high end that to my ears is comparable to the Noble on flat EQ settings.
Basically it's a great option if you need a simple and fantastic sounding tube DI that is a compact and relatively easily powered pedalboard option, and don't require the additional I/O, EQ, and IR features of something like the SLO.
same output with 1/4 out? Have you run Small Trees into RNDI to FOH?
