I had a chance to use this wireless on a blues/funk/top40 gig last week and also tried the cable vs wireless A/B test. Here are some comments:
The unit is very light-weight, compact in size, and easy to set up and operate.
During the live gig, my bass sounded fine except that the gain seemed a little softer than when I used a cable. I figured out the volume trim control inside the transmitter was set too low at the factory. this was an easy adjustment using one of those tiny screwdrivers. the screw is accessed through a small hole in the transmitter casing, so you don't have to take it apart. After turning up the gain slightly, I was able to replicate the same signal level that you get with a guitar cable.
I did not get around to testing the transmiting distance/range of the unit, but I did notice that it worked fine even if I didn't maintain a "line of sight" to the receiver unit (sax player was often standing right in front of my amp and the receiver unit during the evening, but I didn't experience any drop outs.
The specs for this system cite a freq response of 40hz to 20Khz. Granted our low Bs may extend below 40, I couldn't pass up this new toy. I had good comments on this unit locally and the price was reasonable. I did some A/B comparison in my apartment (so, low volume) and noticed that I could hear a subtle difference in freq response between using a cable vs the wireless. The mids and highs sounded the same, but I could hear that the wireless had slightly less ultra-low end than when using the cable connection. I must stress that the diff
was very subtle and that some musicians and definitely all laypersons would never notice the difference. I should also state that I had plenty enough bottom when used the unit on the blues/funk/top 40 gig. The freq response issue does not bother me given the price and convenience of using this unit. Now, if I paid $800 for the unit, then I would probably be upset. Boosting the bass control on my active basses helped to get the overall tone back to where I thought it should be when using the wireless.
For you slappers, the unit appears to preserve that dynamic quickness that you need in your signal chain for delivering fast slapped funk patterns. No complaints here.
Overall, for the price and convenience, I'm very happy with this unit.
