4 effects in one pedal ... A priori with the warmth of analog.

UTILIZATION

Button to select the effect, deus for other parameters. We serve a few of his ears and it works well

SOUND QUALITY

In front of my Mesa correct on my pedal board with 2/3 other pedals and my Les Paul, it has served me some time.
I mainly used the phaser and tremolo and a bit. Wah I was not at all convinced and vibrato, it's not really my thing. The phaser is really nice and sounds rather vintage. But ultimately, the sound quality is pretty bad. We lose the brilliance and dynamic on his hip. It made me so general that I ended up separated me from this pedal.

OVERALL OPINION

Overall, I would say it is a pedal not too bad to start and if you have a small budget. If one is looking a little more on the sound quality, better worth buying effects (albeit more expensive) but better. For example, I replace the phaser with a MXR Phase 90. The sound is less vintage (I have had to buy a model script) but it fits very well in my pedal board.
If it again, I do not would resume, I rather will buy a pedal that does one thing but with better quality.

OVERALL OPINION

All technical details are available in previous opinions, I just wanted to point out that if the charge is most common for this pedal (the old) is the extraneous noise and / or her breath, and although the gap is filled by the wonderful new grind (in a smaller box, little big muff format) that keeping all the qualities of the former is rich in a net improvement in breathing (thank you guys at EHX!), which is in my opinion this pedal a great gadget analog rather practical and original (I use it mostly for the "vibrato" very slow and the tremolo on an old Italian amp with none (or more ... to be honest)).
The rest is of course once again a matter of taste, and try it remains the best option, but if you hesitate to buy it because of the small worries of breath on the old version, be aware that the new n ' has not / have this problem!
I would do this election because four analog effects in a very good tin box (wah, phaser, vibrato, tremolo) for less than 100 balls, should be inflated to really come to complain ... especially if it does not blow!

----------- New Version, little box. ------------

Wah, tremolo, phaser, tremolo.

24v.

True Bypass.

Possibility to control through expression pedal.

LED blinks at rhythm.

UTILIZATION

Utilization is extremely simple:

Switch on, turn knobs, search and find.

Very good quality, robust housing. The switch is straightforward, sec. It's tough.

SOUND QUALITY

Turning one knob we get 4 different effects.

Note that I used the new version in a small housing.
Beyond the simple fact of the obvious space saving, the effect is cleansed of the annoying hum of the previous version. A little hiss appears on some specific settings, but frankly it's barely audible!
Overall, the pedal has a color all its own.
Based on the main effect, namely the wah, the others are developed around that sound.

Controls are effective, useful, and very even.

Wah: An effect very peculiar, strong and vintage-y. The color is magnificent from the first listen. One of the most convincing moduation effects I've ever heard.

Phaser: In the same vein as wah but more subtle, it is reminiscent of the Uni-vibe as used by Hendrix.

Tremolo: tremolo is very limited. Nince tha EHX put it on,  but it's merely a regular modulation. You can not manipulate it too much. It does his job, as it is, but dors not replace a proper tremolo.
Anyway, it's here, and it can be used every now and then. 

Vibrato: The same register as the tremolo but with a little detune. Again, I do not think this is the best. If you are a fan of AC vibrato can do just as well as for the trem. You can use it to emulate a&nbsp;Leslie effect.<div>

Expression pedal function is interesting. I use a volume pedal.

Not necessarily useful, the only pedal delivers its already very interesting and mostly full. For me it helps me a lot. Especially for the wah and phase, obviously, since a tremolo can be done with the volume pedal alone.
Finally, very interesting feature of this effect:

One can freeze te tone corresponing to a momento of the modulation wave. (In position pedal expression pedal but .. lol) We thus obtain tunable filters. On saturation It works miracles!</div>

OVERALL OPINION

Sounds rich, vintage, tubby.

+

multi function
expression pedal
sounds rich and beautiful
breath less
Filters fixed!
PLACE IN THE Pedalboard!

-
trem and vibrato a bit limited.
go, I'll be nasty, dedicated power supply for 24v ...

Ds 4 effects a small box
apparently true bypass


UTILIZATION

Config simple, no manual was loe


SOUND QUALITY

easy editing two of effects are one level below the other two (all sounds pretty vintage):

interresting with wah pedal and efficient (it is not a Colorsound or even a cry baby either)

the tremolo is really nice, simple and effective, vintage

vibrato bof

phaser bof bof

note considers the bargain price (60 euros)


OVERALL OPINION
