3leaf audio GR2
Envelope filter for bass or guitar, analog production "craft", true bypass or buffer (either via simple switch), effects loop, power supply 9 volt battery or power supply type boss. Size: 12x10x5.5cm, weight 406g.


Very easy to use we could do without the manual is very clear. One button sensitivity to suit the output level of the instrument. Two knobs for attack and decay of the amplitude sweep. A button that acts a tone identical tone knob of the bass. Setting wet, dry and clear signal to mix effect. Switch "range" to select the scan rate. Up and down a switch to reverse the scan direction. Inside the housing of other settings: lowpass and bandpass choice for a more bold or aggressive. A switch-res + res and at least for more resonance. One possibility to adjust the gain. A switch to go from true bypass buffer.


Hack it and found very quickly that his cherche.Je use it with my Fender Roscoe Beck and envelope filter works well over the entire range of frequencies. The settings are very sensitive and workable, we move quickly from a vintage sound has a more aggressive manner box bubbles, the sound palette is very broad. The opening of the filter is very sensitive to attack by rendering cordes.Très good slap. Ability to integrate another effect in the loop, I've plugged my big muff and frankly there is huge, good sound to jamiroquai.


I use it for a week. I owned a home ehx enigma (which has blown past), which was more difficult to resolve, with the least usable and adjusted output level that HP did not like always. I tested a jasques trinity, very nice but my taste less versatile, with a lower setting range, and many more vintage. I love the flawless finish of gr2, ease of use, the filter efficiency at the opening and closing the opportunity to spend a vintage sound has a very fun, the effects loop integrated opens new horizons. It's not cheap but it is the price the quality and efficiency. I would do the same choice without any problems.
