How our pages are made
Every fact on a page is cited. Numbered sources appear at the foot of each page, so you can check where a claim came from and judge it for yourself.
Specifications come from the makers first: manuals, product pages and service sheets. History and reviews come from the press, including magazine interviews and archived articles. Retailers are used only to confirm details such as current specifications. When a reviewer or player says something worth repeating, we quote it and credit it to them by name.
We do not test gear ourselves, and we do not give advice of our own. You will not find a "best" pedal named here, because the answer depends on your amp, your guitar and your ears. What you will find is what the maker says, what the press said at the time, and what players actually use, all in one place. Photos are the makers' own and are credited to them.
News
New pedals, firmware updates and discontinued models appear every day. Each news story links to the maker's announcement or the press report it came from, so you can read the original yourself.
