You will need a power supply as a small jack if you want to avoid the batteries (like the TS 808). it is solid: everything black metal! but not too small, slightly angled to fit your delicate feet with love, it's a great pedal fouttue (no pun intended of course ...)
will, as a gift here is an extract of the paper advertising that Proco offer to buy:
"A sound as mellow as a vintage" twin ", or as bone-crushingly Powerful as a battery of stacks Français Those famous" Basically, you are promised the fender like marshall .. c rather appealing and seems to ca its promises!

UTILIZATION

The knob are miraculous! I have rarely seen a pedal that responded as well to any setting. We understand quite quickly how to get to get the right sound. It sets the drive, then with the filter, it handles the equalization and the dose of fuzz sound sought. Finally it suffices to adjust the overall volume. Néamoins Warning: the maximum gain is obtained around 1 am, the rest of the race only adds to the compression. The filter is really great: used in conjunction with the tone of your guitar was a huge sonic palette.
apart from that we can see the fluorescent markings (practice on stage) and the red LED in the middle of R "RAT": the great class!
a small downside, however: the race is more knob gain and irregular especially early in the race. there are big big of a sudden and it will go slowly to make precise adjustments. well I do not blame him for so little.

SOUND QUALITY

I do not have the chance to play on the excellent gear (not yet ....) and well this pedal makes me forget that by the time I play the shit as it's a dream! this is EXACTLY what I was looking for: Hyper versatile, with character and punch! against it or by a distortion or a fuzz or overdrive. So if you want a good metal distortion that might not be accurate enough but it is a must for everything else: you can have a nice crunch, bluesy sound, a very full-bodied overdrive, a distortion dirty saturation apocalyptic! check out the demos on the site! this pedal goes all the styles: Hendrix, May, Mettalica, Hard rock,-M-(see his DVD: the distortion pedal used) and so on .....
added March 26: After some time Here are a few settings
"Fuzz face" dist: 12 - filter: 10 - volume: 11 am. so try it with purple haze! This setting is also quite close to the sound are you gonna go my way (through enposition neck pickup / bridge)

muscular overdrive: dist: 9:30 - filter: 9:30 - size: 12. with a humbucker bridge you're Angus Young. Humbucker in neck you're on Clapton Sunshine of Your Love.

added 24 December 2005: new amp, new guitar with a strat we see that the rat is very quiet despite the simple microphones. now I use it more as a huge boost rather than a distortion. It plays this role very well, I get a well enough grain for an early vintage drive low: a little fuzz to the old. To drive higher, a little less controllable c: too sharp, feedback and company. It feels that the rat is still not made for that.
Reum in the use boost works very well within reason, otherwise it's a mess. It is still a function more for this pedal that was not bad at the base!

OVERALL OPINION

Purchased from the pedal to Pigalle. I for a month. I love everything about her: she has the mouth, the sound, the price! and yes! € 100 ladies and gentlemen! the price of a Boss pedal, but with all more! I also just before an OS-2 which was about the same role. OS-2 was not bad, but there ..... we play more in the same league!! Even if achter a versatile distortion pedal: put € 10 more and give you the best!! All the same!! must be acquired this pedal knowingly! Her well as to many up s'addapter style is very distinctive. You have to buy a rat for the rat's! the sound will never be as precise as a disto classic!
