So this is an overdrive, so the signal is pushed the limit of saturation or saturation by increasing the frequencies wishes ... (Am I clear?)
it is an analog pedals (which makes reference with its high-end gear (it does not sound as dnature effect numrique).

However, the knobs are not numerous enough to correct an eq

UTILIZATION

Congig super simple, one volume knob, one for the Tone (severe acute) and one for potatoes (more or less fishing).

there is even no need for manual

SOUND QUALITY

I use it with a Marshall head era (1972) 1959 super lead (the models), and with the pedals (needless to say that with this type of amp I will not put a pedal Simulation crap that will rot my sound), the sound is amlor in treble and midrange, more harmonics all over ..

we find immediately the sounds of legendary bluesmen hendrixiens.

This axis pedals st enough in the medium, and now many references used to obtain softness with more bass without the gaudy print.

I drop the doc note 6 (I sold the pedals ago logtemps in my qute the overdrive now I'm on a Wampler Ecstasy (from years of this Lumire maxon).

OVERALL OPINION

I used it for 6 months.

I couple of distortion pedals with pedals and a Boss DS2 Boss CS3 Compression), and well with distortion, overdrive adds a lot of nuances in the saturation, allows for example to make it last super long notes (Santana) and add the brilliance with which I will flap their ears from the beginners of this notice.

my opinion is that this kind of small analog pedals transcendra your sound if you have good stuff but not turn the sound, if you play with an electric 200 euros and a 5-watt amp park, will be a funny but not as a pod ..
