I was facing exactly the same problem, but with Revolution Solo II. Actually 've been facing this since I bought the pickup almost three years ago, but I got used to a weaker G. My amp is GK MB150E, but the same occurred with other amps. The same weak G always happened too with Fishman BP100 (wich is by now retired). G string is low, 6 or 7mm.
But then I got tired and decided to investigate and try something to solve this and keep using Revolution Solo.
Final solution after several frustrations: dampened the tailpiece afterlength with a cut piece of rubber pipe (G, D, A, Ab, Bb, and B notes were ressonating too much on the afterlength and I suppose that when amplified were stroking G harmonics).
Other effective thing was facing the pickup towards the top instead of the strings, E side. Now I'm getting an even sound full sounding G, really the acoustic one, couldn't be happier. And reduced 90% feedback issues.
Arco sound is amazing, sometimes i have to to check if it's really on because it's just my bass but louder.
The "bad" thing about reproducing the real acoustic sound of my bass is that if there's anything wrong like an uneven acoustic sound, any ressonating frequency, buzz, the amplification will just "amplify" it, no fix or platting anything. For instance, my A string sounds acoustically poor on the first positions almost no fundamental, and Revolution Solo don't fix it, just reproduces. On the other hand BP100 could mask it somehow and made those notes sound good, but it wasn't the true sound.
My happy ending is that these simple improvements on RSII stopped me from spending another $230 on Full Circle, which I was decided to get without being sure it would resolve. And the funny thing was that actually the amplification problems concerned mostly my bass acoustics characteristics, the only thing done about the pickup was turning its face to the top.
Forgot to mention, another thing was using a copper wire in the pickup jack to isolate an eletricity noise that was affecting Bb and making it rattle and feedback, especially Bb on G string and a little less on A string, Bb octave lower.
