I use the OS2 in the FX loop of my Tonelab LE and I can say it can double the Tonelab's abilities. Pros Each knob does excatcly and clearly what it is meant to, pedalboard friendly size, good handling. Cons When battery runs completely dry its tone messes up which is quite embarassing, very digital sound for my taste.
The Boss OS-2 gives both overdrive and distortion effects in one single pedal. A large range of sounds and levels of saturation can be achieved with just a few tweaks.
Four knobs are available: Volume, to control the output volume (this had to be adjusted at the end to ensure maintaining a similar volume with the effect turned on and off). Tone works like a Low-pass filter, allowing adjustment of the high frequencies. Drive controls the amount of drive for both the overdrive and distortion. Color allows you to adjust the blending of the 2 effects: at extreme left, only the overdrive will be active, at extreme right, only the distortion, and right in the middle the two will be equivalent.
I use this effect with a Fender Stratocaster with no Humbuckers. I prefer the distortion part of the pedal, which is quite rich in harmonies for this price. The overdrive sounds ok when blended with disto but it's a bit cheap on it's own. Also, I couldn't manage to get a crunchy sound with it, even with Drive very low the overdrive kicks in pretty quickly, but it might be because of my configuration (I play on a bass amp Orange Crush). Globally the effect sounds quite standard, don't expect to be surprised by it's "personality".
On the robustness side, nothing to say, it's Boss and it's tough! The battery case is easy to access (under the foot switch) and needs no screwdriver to open. Besides the pedal is delivered with a battery already in. And of course, there's a socket for an AC adaptor.
To conclude, this Boss OS-2 is a very handy and affordable solution if your playing requires a wide range of saturation and you don't want to carry too many gears. But you might want to color the sound with other effects if you want something less ordinary. I would fully recommend it as a side-effect for it's large range of tweaking but less on it's own.
