This is probably going to be a very short review of this pedal. I will start of by saying on this, it is and amazing piece of gear, very unique and sounds fantastic, add in the toggle switch of voicings and you have one hell of a package. I brought this pedal after seeing a demo with Tom Quayle, although he was using the Dual Fusion (which was very very impressive), there was a lot of talk about this one, and it seemed to suit what I was looking for (in the ultimate OD quest). I loved the idea of being able to get a lovely Dumblesque tone in a pedal, I really thought that tone was for me, I loved the idea of a transparent pedal, letting the voice of my guitar speak out, I loved the idea of owning a Wampler, this was the perfect pedal….but I sold it!So most importantly what does it SOUND like?Don't get me wrong at all, this really is an outstanding pedal, one of the best pedal's I have ever tried (and owned briefly), it sounded truly lovely and stunning simply plugged into the front of a Fender amp. In the 'smooth' setting, you get (supposedly a Dumble type sound), having never owned one of these mythical amps (for obvious reason), I do have a rough idea of how it should sound. I guess to my ears it has a smooth openness to it and a nice sustain, characteristic of said Dumble, so yes it works. It is ver open sounding, very clear and not muddy at all. I think smooth sums it up perfectly! Switching down to the 'open' mode, you get an almost clean boost here, it is practically transparent and drives the front end of an amp very nicely, there is a lot of gain here, and you really hear your guitar coming through. I should say it is almost perfection. The 'crunch' mode really is probably the most like a traditional overdrive pedal and can get quite fuzzy with the gain up.But, it wasn't for me, I can't quite put my finger on it, logically and aurally it was a perfect pedal, but I guess I wanted something a bit dirtier, perhaps something which added a bit of character. I am not quite sure, but I think I found it with the Fulltone Plimsoul! I seriously suggest if you are looking for a transparent sounding overdrive/clean boost and want to sound like Robben Ford or Larry Carlton, that you head down and check this pedal out quickly.How easy is it to use?Very easy, I mean it is an overdrive pedal. Select your voicing, and turn the gain, volume and tone. The Bass control is interesting as it enables you to control the bass in the signal, which is kind of unique in OD pedals, because it helps prevent the sound getting over muddy but retaining mid punch and clarity!! Very nice!Are there any nice touches?Love the little bag Wampler Pedals come in. The Bass control!Will it fall apart?No it is solidly built for sure!! I love the construction, it is almost sexy!Pros1)It sounds fantastic, like really fantastic, like super fantastic and transparent2)The different tones available from the voicings3)The level available and the Bass controlCons1)It is expensive, very expensive!2)May not be quite what you are looking for (as in my case) PeaceNeil
