To get a great sound out of a great sounding microphone you will need a great pre-amp. And for recording guitar you will need an audio interface with low latency. Focusrite thinks their new models covers both issues.
At NAMM 2015 Focusrite has introduced its new Clarett Thunderbolt interfaces with extremely low latency: below 1ms! It comes in 4 different models, but all models come with new Clarett preamps + a classic ISA design switch. And they are all expandable over an ADAT connection.
I do wonder though how the extremely low latency relates to CPU usage. My current Focusrite Scarlett 2i4 interface (USB 2) can handle 128 samples in Ableton and Reason but only when doing very simple projects with really just a few tracks and without any complex virtual processing going on. I am wondering how the Clarett will handle this. Below 1ms sounds great, but I am more interested in the safe setting here. Hopefully that safe setting will be something like below 6 ms even on very demanding tracks/projects!
There is something I felt was missing compared to my current Scarlett 2i4 interface: the pad switch. I always have the pad switch ON when recording an electric guitar or bass guitar. The pad switch adds more headroom to the input signal. Without it I am overdriving the input and ruining any digital recording with lots of audio clipping. Maybe Focusrite has removed this switch on the Clarett models and added headroom to the input level.
Not sure if it can work on bus power, probably not since all models contain a connector for a power adapter on the back panel.
Would love to try the smallest model the Clarrett 2Pre as soon as it is available.
