Great overdrive for rock type sound

Sounds great and has lots of possibilities to create your own custom solo or rhythm distortion. Best suited for classic rock style, not for HM stuff, but a great choice for many other styles and purposes. Be sure to get the Plus version with extra boost function!

Big overdrive sound

This pedal is absolutely awesome! You can turn the knobs wherever you want to without getting a 'bad sound' out of it. The overdrive sounds very organic, fat and yet transparent. It works well with almost every amp and can be fine-tuned to sound like the Gain Channel of almost every amp. Very flexible, works well with your volume-knob and just sounds like it should: Like a beautiful, solid and fat medium-gain-overdrive. The second gain stage is what makes this pedal even more flexible since it only adds more gain (as much as you want - choose it with the + knob) while all other adjustments stay the same. All in all the best overdrive I have heard and played in my life!

Time pays

This is a great vintage style boutique over drive, hands down greatness. It has a beautiful two stage system, that does just enough rather than too much. Its only down side is you have to put the time in to set it, there is so much customisation for the sound you get that you have to spend the time, but if you do, you won't regret it. It is very responsive to touch and the volume nob, little changes make but sound changes. If you want a great pedal that is reliable and will cover almost all situations you throw at it, this is the pedal you want.
