Apparently the LX comes with the Tone Pump Standard, or the Agggie, or the EmG preamp. Can anyone give me a basic rundown regarding these three preamps. I'm leaning toward the Emg system mainly cuz a youtube clip of Ian Hills custom bass showed the Emg pre....and to my ears It cranked. What are your thoughts about these preamps and the resulting tone from each.. I know thats maybe asking alot, but seek and yee shall find.
