It is a trmolo with 3 knobs:
- Shape (see variation in length of phase)
- Rate (speed)
- Depth (depth)
+ A slecteur the shape of the envelope.
+ Diode on the support of the switch to see if there is bypass or not.
one between an output.

The pedals are big enough, strong enough. I like its look.
on the other hand, it is cumbersome in a pedal board.
Warning connectors for food (mini-jack 3.5), but with an adapter will do (I personally am not a fan of batteries).

I put 8 because:
10 to 1 for the mini jack
and
10 to 1 for the "size" of the pedals.

UTILIZATION

Of course, I said above that the pedals are great. The knobs are large, and it is also an advantage. RULES sound is very easy, with precision, trs quickly.
The diode is effective (which is not true of the heads o pedals even when the LED is lit, you really have to be above the pedals to view it)
No need for manual, everything is intuitive trs.
It's easy to find her.

SOUND QUALITY

So it's the slap!
I love that sound ...
Dj there is no "alteration" of the original sound, you really the sound of your amp with the tremolo effect.
The knobs allow a standard palette of sound, slecteur (triangle / rectangle) also allows to vary the effect of Manir more or less progressive / radical.
Combin a Dlay, we can do stuff ... Dlay well even without recess.
My rglages prfrentiels are of type 4 / 10 and 6 / 10 on the two knobs on the right.
Concerts as RPTES, evokes the problem with the switch has never reproduced at home.

on the other hand, beware not to put too much substance, it is not personal at last the sounds m'intressent.

It colors the arpges its clear a shell on the distos grnages ...

I play with a classic 30 or a Marshall with a telecaster, I sometimes combined with a delay AD-9.

I put 9 / 10 because I did not test other tremolo pedals, so my opinion is not forcment trs goal, but it gives me tremolo Entire satisfaction.

OVERALL OPINION

I use the pulsar for 2 years.
Bcp liked its looks and the size of the pedals, which becomes a "inconvniant" From the time you want to combine a lot of effects or if it is to carry around in its cover guitar because the small btete takes place quickly. At least the pedals are rugged and reliable.
But the main strength of the pedals is what it was in the belly, and it's really pure happiness. The sound is incredibly warm, and if you like tremolo effects of "You" Radiohead etc, go for it you will not be caused by the pedals.
The ratio quality price is excellent.
Trs sign of good hardware Electro Harmonix, again ...
