I'm not a fan of the Evolution pickup at all, even though I play some shred. If you're gonna run it through a Recto of any kind, there are two main things to keep in mind. First and foremost, the pickup by itself is shrill and strident in the treble. Couple that with the Recto's well-known glassy presence and the sound can be nails on a chalkboard. Kill the presence completely. Turn treble on the amp down to approx. 10:00 to noon at the highest.
The next thing is that the pickup is not a very fat-sounding one in general. As such, you will need to beef up its midrange harmonics. With a Recto, this means running an overdrive, not a boost, in front of the amp, likely with the tone knob on the pedal turned down a bit as well to avoid those glassy highs again.
Keep the mids on your amp no lower than noon, and bass no higher than 2:00. All of that put together should get you a useable tone. Frankly, it's a poor pickup choice for any amp that produces a lot of presence, so I'd ultimately recommend that you sell it and get a pickup with a fatter response and tamer highs.
