I bought this with my recently purchased new electric guitar, looking for that rock sound, and the product delivered - briefly. I tried it once, and it worked fine. Tried it again, it didn't work. Puzzled, I checked all the connections, everything was switched on, the lights were on, and yet the distortion pedal didn't work. So it worked once, second time? Not so much. I didn't drop it, it wasn't damaged in the post, nothing like that. I kept it safely on a side table but for some reason after one use, it died on me. Luckily Amazon are good with refunds and gave me a full refund once I explained that the product was broken.
Side-note: If you're planning on buying this you'll need a 9V adaptor and a guitar lead cable jack, both of which aren't included with this product. You just get the distortion pedal, nothing extra that you need to get it to work.
