K&K Trinity Pro Mini System

I had this installed in my Lowden equipped with Fishman Natural one piezo pickup. For big gigs I use the blend of all three, which gives a great, full sound. I spent a while playing with mic position and the preamp setting the gain and EQ knobs inside. Excellent option since all guitars would react differently to the settings.
Often I use just one signal. I run a mono cable and use the passive pure mini together with l.r. baggs session DI, which gives a great combination. I forget what a battery is and never worry whether it's full enough. The sound guys were amazed how natural the guitar sounds.
100% of recommendation for this system.

I saw this set in Beppe Gambetta's guitar. He uses with the Quantum blender, but majority of the controls are in here too - even it's not to easy to reach. But that's the price of the portability.

The transducer is the best you can get. No feedback, good sound. That's a solid 5star product - honestly, if you playing plugged, this part is enough to have.

Mic: I use rarely, it has way lower output than the transducer, so fiddling a bit with the gain control is crucial. Blending to the transducer, even slightly, it gives body to the tone. The problem is: it's microphone, so you'll get feedback issues.

Preamp:
CONS
- Would be good to have a notch filter (see Fishman ProBlend) for the mic.
- In case of slapping the strings at the bridge, it clips out the system - that i did not experienced from the Radial PZ-Pre.
PROS
+ portability. Small, well engineered, stable.
+ easy to use - if you're familiar with trimmer pots. :)
+ no battery in the guitar!

Cable: change it please immediately. Very cheap, and not fit perfectly to the guitar plug. Get a good L-shaped stereo plug for the guitar side.
