I have recently bought a Gibson J45 (about 3 - 4 years old). It's a lovely guitar and sounds wonderful acoustically.

The Element Active (factory fitted) works nicely but I detest the quack... so I took the UST out and fitted a Takamine Tri-Ax (basically an M1-Active) taken off my '60s Martin 00-18 (upon which it sounds wonderful).

The Tri-Ax didn't sound any good on the J45 either - boxy and very electronic! (Very frustrating as the house-guitar of the session I play at is a new Martin with fitted electrics that sounds just wonderful through the PA whoever strums it!)

Anybody got a J45 and having similar problems? And anyone got any suggestions as to where I should go from here?

Many thanks
