I bought it for live gigs so i can pair it with Rumberger K1x2 pickup for saxophone. I must say I was disappointed . The signal strength is way to low for that Rumberger. To get decent signal, you have to put a LOT of gain on the mixer and transmitter as well. (+40dB on mixer and 0dB on transmitter) at which point there is lots and lots of floor noise. I sold it immediately and bought EW100 G4 here on Thomann which is way better,signal is four times stronger than this XSW 2, (on ew100 is only +10dB on mixer and-9dB on transmitter,and very little ,almost no floor nosie). Sound is good,and on other instruments it works great,but for saxophone and rumberger pickup you must look elsewere.
