Stock, it sounds great, but with the C6 removal mod, this thing is PERFECT

My son loves this pedal thing

Modded, this thing becomes an absolute monster of a pedal

The main thing I noticed when playing this pedal is that your nuances in playing and picking aren't lost in a sea of dirt

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

It requires a bit of fiddling around to get the right sound you want, but I think that's a good thing since it lets you try out different settings

This thing freaking rocks

But if you understand what this pedal is supposed to do and use it for that purpose, you'll understand why this thing has been popular for over 30 years.

Because I'm a cheapskate (and because these things are durable like bricks

Great tone with an epiphone les Paul standard pro through a fender frontman 15g
