Well I didn't start out the day intending to be able to compare the two. Nor did I want to. But Focusrite wins hands down. I started out buying the PreSonus. Got home, hooked it up, and there was all kinds of snap, crackle, and popping sounds. It didn't matter if I went DI from my Ampeg or GK or line in from the bass. Which DAW I used, which USB port I used, or which USB cable I used. Or if I even had anything hooked up to the PreSonus at all. The minute I hit the record button in any of my software packages, snap, crackle, pop. It did send the bass signal to the computer, but along with snap, crackle, pop. After about 45 mins of using various software programs to record, it finally just quit and the computer couldn't see it all. Anyway I took it back to GC, that's a whole other story. Let's just say there's a reason I don't do major purchases with them, and I veered from that philosophy today, never again. After a brief 10 minute customer relations toe to toe tangle I got a Focusrite Scarlett Solo 2nd Gen, paid the difference after I got to use my 15% off coupon on my phone for the 2nd time today. So I got home, uninstalled the PreSonus drivers, installed the Focusrite drivers, cranked up Soundforge, nothing but bass coming through to my recording track. And the build quality, definitely better. The knobs on the PreSonus were skewed and had a wobbly circular pattern to them. Not the Focusrite. Everything is all nice, straight, and aligned perfectly. The clipping rings around them go from green to yellow to red instead of some LED dot that just lights up red on the PreSonus. It was like night and day. I guess it's really not a fair comparison. Obviously the PreSonus was defective. And defective units slip through the cracks all the time. But next time I buy an interface, if Focusrite makes it, that's the brand I will be buying. As far as GC goes, well, I'll stick to only making minor purchases there such as strings, cables, or straps, and only if my locally owned music shop doesn't have what I want in stock.
