## Questions & Answers

**Q: What is the diference within this V2 and the other?**
A: VERSION 2 
With the popularity of 5- and 6-string basses going beyond fad status and becoming mainstream, we added a switch to adjust the bass frequency to extend into those lower registers. We also added a mid-range control and a switch to adjust its frequency. The core of the SansAmp Bass Driver and all of its tones remain true to its original design

**Q: Does it comes with adapter?**
A: No I had to buy one separately. Found mine on amazon. It can also be powered by 9V battery tooI think it sounds great I highly recommend purchasing

**Q: Can i split into two amps? And if so will one output be dry?**
A: You can run a Sans Amp Bass Driver DI into a power amp. One side of the power amp can drive a 2X10 bass cabinet and the other side can run a 1X15. You have to run one side of the amp from the 1/4" output on the Sans Amp, and the other from the XLR output.

**Q: Is it programmable, does it store settings?**
A: It does not have any programmable features or saved settings. Just the dials and buttons 😎
