One, this one and the second the Tascam 144 MKII. I have been looking at every place with reviews, opinions, etc and I ended up with two options. I have been looking for an external audio interface for a couple of months.M-Audio Fast Track Pro USB Audio/MIDI Interface Instrument port is clipping with bridge pickup at 0 gain. I have Gibson Explorer with stock pickups (496 neck/500 bridge). They claimed the clipping issue is fixed in 2nd Gen, but it's not.The unit will not light up, although I do not have speakers, though my friend bought the same Scarlett Solo and he ran it just fine without speakers. I followed all the instructions and watched all the videos, looked at all the guides. The built in preamps are great! If you know how to mix, automate, use your plug-ins and have a tight recording, it's totally possible to make a recording that sounds completely professionally produced.I love my Focusrite Scarlett Solo! It sounds incredible, there is zero latency, the illuminated clip rings are very nice and functional, it is built like a tank and looks very nice.This is great for anyone wanting to record one track at a time.The second-generation Scarlett boxes are simply amazing, tons of headroom and lowest latency yet!.Focusrite Scarlett Solo Audio Interface with Pro Tools
