Its a great little unit, I just haven't been using it much these days. Perfect unit if you just need one really good preamp for a project studio or something.
I would describe the sound of it as clean but not totally transparent. It has loads of clean gain and a lot of beautiful character and detail, especially in the upper-midrange.
This preamp stacks really well in a mix if you're recording multiple parts on it. It especially sings on electric guitar and vocals. I've also found the impedance settings to be super useful in getting several tonal options out of a single mic.
The DI is a nice feature as well, and it runs independently of the preamp so you can record through both of them at the same time. NOTE: This unit does not have the A/D converter in it, so if you are planning on doing digital recordings with it you will still need to run it through some sort of audio interface. The unit is tested and fully functional and includes the original box. The item "Focusrite ISA One Professional Single Channel Mic Pre-Amplifier with box" is in sale since Tuesday, June 5, 2018.
