The Boss SD 1 is great for 40 bucks, what more could you ask for. Give it a try and you will see how great it sounds for a very cheap price. This pedal is great for blues music, I generally set my settings at around (Level 50% Tone: 60% and drive 90%) That’s what works best for me. But you will have to play with it, because if you have all the knobs turned up its really noisy. Only complaint is the distortion bleed-through, but I don't use it on settings that high . It comes in a yellow and black color which is a good combination that you will never forget to use because it sticks out.


The circuit is very similar to that of a vintage Tube Screamer, except for the addition an additional diode in the clipping section. The resulting asymmetrical wave pattern produced a deeper, richer bass response than the Tube Screamer’s symmetrical clipping section. The SD-1’s sound is also less focused in the midrange frequencies than the Tube Screamer.


There is a negative to this pedal...with some guitar and amp combinations, when you max out the SD-1’s Drive and Level controls, you can hear some distortion filtering into your clean sound even when the SD-1 is turned off. This phenomenon is inconsistent; i.e., I have heard it at times…other times I have not! To remedy the problem, back off a bit on both the Drive and Level controls or perform a simple circuit modification improves the bypass circuit and eliminates the bleed-through.


Overall, Alone the tone is not so great , but behind a good distortion or fuzz pedal this thing sounds amazing. Sounds best coming through a tube amp, looses a little of its bite coming through solid state. Bump it in on a tube amp with a little fuzz and you'll love the tone.
Give this pedal a shot, you cant beat it for 40 bucks!
