It sounds good when used on the top boost amp channel and pushing it even harder, but frankly I think it sounds best when used simply with a good clean tone on the amp

I was just starting to take guitar seriously, and I was wanting distortion for my Crate G-10 amp.

It makes dynamic amps like Fenders and Voxes sing while tightening up the response sort of like a compressor.

I use it to boost an overdriven amp already, by itself on a solid state and pretty much in any application you can think for it because I like to experiment as a bedroom strummer

Clean amp setting with the Super Overdrive kicked

My experience with this pedal is actually a bit different than many of the reviews here; I have primarily used the SD-1 as a distortion pedal with my solid state amp (mid-80's 35W Sidekick Switcher) and a Telecaster with Fender Noiseless pups

sound a bit different, so it could just be my gear, but I have to say that while I love this for a tube-like drive for a solid state amp, it sounds cheesy with actual tubes.

i was using a line 6 solid state amp

I like the Boss Overdrive for fact that it a great booster to your amps own overdrive or distortion

And that's the way I've always played it, running it behind an MXR micro-amp clean

Great for finger tapping and pinch harmonics, the SD-1 is without a doubt the best thing I could have ever done for my cheap Acoustic G-10 amp

I like to use it to warm up my cleans and push my amp (like a booster) and then turn it up just a tad more for that nice bluesy thickness with my tele

I use the SD-1 primarily for worship music in our church's band and have it going into the front of a clean amp (a Tech 21 Blonde).

As with any overdrive, this thing will not sound very good (IMHO) running into a solid state amp.

If you have a good metal amp that can stand for a fair shot of juice, this one will definitely provide

It took my cheap amp and turned it into a bone crushing metal machine

sound a bit different, so it could just be my gear, but I have to say that while I love this for a tube-like drive for a solid state amp, it sounds cheesy with actual tubes

Back then I had cheap guitars with crappy pickups and solid state amps that were thin, sterile, and lifeless.
