AMPLIFIED PARTS Compares Three Popular Spring Reverb Units

Now, this is real sweet! Maybe next somebody could finally explain the difference between a phaser and a flanger to me…


Popular gear reviewing YouTubers Amplified Parts have decided to make a comparison video between the popular MOD® 4AB3C1BBelton 4AB3C1B, and Accutronics 4AB3C1B spring reverb units.  In the video, you can clearly hear that just like compressors or preamps, no two spring reverb units sound exactly the same. My personal favorite was the Accutronics unit, which has that super deep and lush post-rock-type echo on it, but see for yourself which one you dig the most!

These units would be something that you could swap out with your current reverb tank for a relatively low price point. The most expensive unit in this video doesn’t even cross the $30 threshold.
