Electro-Harmonix Tube EQ

Qualisation to-analog pedals with lamps.
-2 Lamps 12 AX7
-A input, output, and accounts for an expression pedals.
-Comes with its own transformer 220 V
Potentiometer-cot: acute, bass, frequency, bandpass, and q (expression pedal)
- A switch to enable or disable the pedals.

UTILIZATION

-Doc in English but not too complicated to understand good
-For a sound, it's easy action on the potentiometer and the sound changes very easily bass, treble, and especially the frequency, then mixes it with the bandpass.
-Very convenient when using pedals with an expression pedal (I'll talk about below)

SOUND QUALITY

-So here the party fache
-This is only my opinion: its rating in clear improvement of bass, treble, and modifying the knob of frequency we obtain a sound equivalent to wha wha pedal.
"I try to change the saturation qualisation on my jcm 800, and it's a catastrophe, its blurs, saturation dribbling, unplayable.
In addition, loss of earnings in between the amp and pedals that j'enclenche.
- To continue, I do not think it is a real qualisation, but rather a change in frequency drives wha wha-style with addition of bass and treble. So the only interest that I find the pedals has is the ability to act on the pedals of a frquence exprssion, but in this case it's more a wha pedals wha, an equalization of pedals.
Conclusion: Use plain to get crystalline sound and use pedals with an expression to extract its full potential

OVERALL OPINION

I test-5 pm in all directions on a jcm 800
configuration directly, or through the effects loop.
- I do not spar am not suitable to the type of EQ that I seek.
- The price: two lamps, a nice brushed aluminum pedals, a transformer, I would say reasonable.
