[SOLVED!] Fulltone OCD vs Tube Screamer – The Better Overdrive Pedal for You


Do you want to add some spice to your guitar masterpiece? Overdrive pedals to the rescue. Popular ODs that have invaded most of the music studios and concert stages worldwide is the Fulltone OCD vs Tube Screamer. To further unveil the greatness and power of these popular pedals, let’s start by getting to know what overdrive pedals really are.

What are Overdrive Pedals? Distortion Pedals?

Before we dig deeper into the comparison of Fulltone OCD vs Tube Screamer, let’s understand what overdrive pedals are first. Perhaps, let’s also have a quick comparison with the distortion pedals, so you can understand which is better.

Overdrive is the phenomenon when the tube amp is pushed to its limits and the signal hits the ceiling. The signal is more likely being “clipped” in this situation or the waveform has been cut off due to the limitation of the tube. Using overdrive pedals, it’s much easier to recreate this tone and even the process of creating one. With the overdrive pedals, you can achieve sweet, fat tone. The harder you strum the guitar, the more power and angrier it may seem if you use the right pedal in the right “overdrive” circuit.

Distortion pedals, on the other hand, provide even harder levels of clipping. The more clipping stages you’ll have in your setup, the higher the distorted gain. It’s very important to do the clippings right, or you’ll end up having too much white noise. However, if you have a great distortion circuitry, you can achieve more complex chords that may add a great amount of sustain to the sound you produce.

Distinguishing overdrive from distortion effects helps you get a solid grasp of the comparison between the Fulltone OCD and the Tube Screamer.
