OS-2 Overdrive/Distortion

Get a taste of both worlds (overdrive and distortion)

The BOSS OS-2 is a pedal manufactured by the Boss corporation. It is what we would call an ultimate gain pedal because it can go from slight overdrive to a shredding distortion. All from a single device.

Literally, it gives you a taste of both worlds, making the statement “less is more” very false. In this case, “more is more.”

It is an ideal pedal for any beginner or intermediate player. Is it worth the hype? Let’s find out.


What are the features?

BOSS OS-2 is a standard gain pedal with the custom design found on many pedals out there. However, the BOSS OS-2 is not far from your pedal.

The OS-2 is not just one pedal, but actually two great pedals in one! On one hand, it is an overdrive, with all the different levels and the subtleness that entails, and on the other, it is a massive distortion.


What makes it special?

A sturdy metal body

The BOSS OS-2 has a full yellow metal body. This ensures durability and a reasonable lifespan.

It is a very light pedal with a weight of 0.4 kg and dimensions of 5.9 cm (height), 7.3 cm (width), and 12.9 cm (depth).

The body houses knobs, two side jacks and a 9V battery.


Dual-based control

BOSS OS-2 has a footswitch to turn the pedal on and off. A 9V battery powers the circuit.

It has four control knobs to control the type and range of amplification you desire.

The level knob provides high levels of distortion and overdrive, and the tone knob controls the degree of brightness of the tone effect. Also, the drive knob provides a thick metal crush to your sound when you increase it.

The main knob is the colour knob which helps you switch between distortion and overdrive.

All factors taken into consideration, the OS-2 is very easy to operate.


Full metallic performance

With this pedal, you can actually combine both distortion and overdrive and create your unique sound. One quality of the BOSS OS-2 is that its distortion keeps the subtle nuances of a single-coil pickup unharmed.

Because of its simple form, this device is just ideal for beginners and intermediate players. However, it can also serve professionals, just that the distortion levels are moderate.

In conclusion, the OS-2 produces high-level metallic effects and is usually used for hard rock.


What’s our opinion on BOSS OS-2?

We liked the OS-2 with both Humbucker and Single Coil guitars. But to see what the BOSS is really about, check it out on the TonePedia player. It is used with a Strat, and you can set the pedal to different gain stages to monitor the effect.
