Great pedal!


This was the first pedal I added to my pedal board and it performs amazing. It sounds fantastic when it's set to low or high gain and I've been using it a lot ever since I got it.



I like to buy one more





Can't go wrong with the pedal or Sam ash


This is a pedal that I've always steered clear of because of price and because I always thought you had to buy botique. Plugging it into my Mesa boogie Fillmore, I am now silent on thinking this is a junk pedal. But sound is also subjective too.




The classic overdrive that runs head to head with a TS9.


If you are looking for a great affordable overdrive that can cover a wide range of music, this pedal might just be for you. This really is the Boss answer to the classic TS9. It differs from a Tube-screamer in a few ways. It has a bit more gain on tap, it has less mid range coloring and just a touch more volume. It works great with other overdrives as a boost as well. Probably one of the unsung pedals in the entire Boss line.

I would buy this product again


A basic pedal. Easy to use. Gets as dirty as you want or as smooth as you want. Works great. The price is right too.

This was my first trip in to effects land.


I use this pedal around the house, mostly for a mild overdrive and it's pretty good at doing the dishes, so that's a nice bonus. It does it's job well. Not a heavy distortion, but some nice dirt. I would buy this again.




Basic and does what it should.


I got this pedal just to add some distortion and sustain for lead solos,however you can also leave it on all the time if you want. That's just a matter of personal preference. I like how it does not change the sound of the guitar, just adds an over driven tube amp sound. It adds crunch, and bite to your picking attack. There are lots of other overdrive pedals, most of which are more expensive, but the Boss SD-1 is a good pedal for the price if you just what to add some meat to the sound of your rig.

Enticing price, terrible quality control


I'm a beginning adult guitarist and wanted to play around with the different sounds that I could get from using a pedal. Not wanting to spend a ton of money I found the SD-1 came highly rated and at a good price. The pedal came and I plugged it into my small tube amp and began noodling around. At first the unit was great. Again, I'm a beginner so I'm sure that I wasn't using this thing to it's potential but it was still fun to hear the different sounds I could get. I used the pedal maybe 5 times in my basement, never out of the house, no gigs, nothing like that. Around the fifth time I used the pedal it started acting up. With the pedal hooked up but not activated I had no problems. When I activated the overdrive I would get static coming through the amp. Thinking it was either a cable gone bad or a tube possibly going out I swapped all that out for new items. The problem persisted. I contacted the customer support by email and got a reply saying that the pedal sounded defective and would need to go in for repair. Remember, this is a brand new pedal that has been used a total of two weeks at this point. I called the customer support number included in the email to talk with a representative. They agreed that the pedal needed to come in for repair and that I would need to pay for return shipping on the item. As the product was brand new, for me to pay to ship back a clearly defective item was inane. I told the representative this and was told that's the way it was, take it or leave it, then I was hung up on. I called back, different representative but same answer, this time I wasn't hung up on though. I would understand if the pedal had been used longer but this pedal was two weeks old. I refused to spend any more money on a product of a company that completely fails to cover a defective product. In the future I will take my purchases to other manufacturers that will actually back their products. The low price of this pedal is enticing but indicative of the quality to be expected.

boss did it again!!


This pedal should be worth more money. Its an amazing pedal!! unlike other distortions, this distortion has tone. The sound is clean, but edgy and not too muddy.

Awesome Pedal


This pedal had just the right tone I was looking for. I would recommend this for anyone. It also has a great price for what you get from it.
