SansAmp PSA 2.0 Preamp Pedal : useful

I use it in conjunction with my amplifier, the Roland Cube Street ex. I connect a mono output from this amp to the "line in" input of the pedal, and then I connect the "line out" of the pedal to one of my Scarlet Focusrite 212 interface inputs. As the sound goes into the computer to a music software, I can hear it through my headphones (they are connected to the Focusite), and as I adjust the volume levels of the sound coming into the software, I start to tweak the various settings on the pedal: drive, crunch, punch, buzz, level... etc until I have got a sound that interests me. What this pedal does is it increases the volume and sustain of the sound coming from my electric guitar - which is already amplified through to the amp - and determines the quality and amount of distortion of that sound. The distortion from the pedal sounds better than the distortion which comes out straight form my amp. I use it mainly when I need to solo with my guitar, on the single notes, to have more sustain, clarity and cleanness. When I strum it's OK, but I usually lower the volume of the recording of the strums compared to the recording of single notes. You have also to adjust the equalizer because the sound can get a bit too high in frequency with this pedal, but it's a good way of creating interesting sounds for your guitar, I recommend it to those who don't have a really good and expensive amplifier like those Marshalls, and want more possibilities with their sounds.
