I have an Ernie Ball Musicman Stingray 5 and I recently bought a G&L L-1505. I had a nice offer on it and after reading lots of reviews that named it the "logical upgrade" to the Stingray 5 I decided to buy it, although I knew of the "not so active preamp" trick in this bass. The preamp is the lesser problem. It is absolutely noisy and feels like a Fender (wich I hate). It can be stringed through the body, but then again it is unplayable (it's already unplayable stringed through the bridge alone, so just figure it out...). The sound isn't comparable to my MM at all as I cannot take out the auful midrange it produces (because of the lack of a mid cut knob -just treble and bass-). The "active features" are totally useless (this bass doesn't need active treble boost -the only active control it has-, but needs some bass boost and the mentioned mid cut). I shielded both cavities myself and reduced the noise significantly. But in the end, the bass sucks big time both in sound and in playability (the neck is so thick it can only be compared to that of a Warwick). So, my question is, WHERE THE HELL ARE THE "LOGICAL MM UPGRADE" FEATURES??? Maybe there's something I'm missing about this bass. Maybe there's something really amazing that's hidden within this brute diamond. I can't find the "INCREDIBLE FEATURES" of this bass compared to my Stingray 5. AM I MISSING SOMETHING? IS THERE SOMETHING I DON'T KNOW ABOUT THE QUALITY OF THIS BASS??? I CERTAINLY CAN'T FIND IT. PLEASE, I NEED TO KNOW THE ADVANTAGES BEFORE I SELL IT!!! THANKS SO MUCH!!!
