3 knobs: Volume, Tone and Drive

UTILIZATION

use could not be more simple, 3 knobs is not very complicated ^ _ ^ '

SOUND QUALITY

Then, j love it! Not only as an overdrive pedal it stands up very well and we get a good sound easy but what's more it takes on the role very well boost! It was in itself that I use and coupled with the overdrive of my amp Marshall MG50 DFX or my Boss OS-2 is a real treat, a boost clean and efficient, just what need (with the right settings of course).
FYI, I use a Fender Telecaster Highway One

OVERALL OPINION

I have for a week but I had already tested previously and different amplifiers.
I tried several models before, but one that is my favorite by far!
What I like most is when I use it as a boost or coupled with another pedal, I find that the result is great and I love the tone produced.
The price / quality ratio is very good, especially compared to the astronomical price overdrive and finally are no better than this small SD-1!
I do it again without hesitation that choice =)
