If you just want to connect your computer or phone to the amp wirelessly, then the inexpensive Bluetooth receiver is all you need. I also wanted to eliminate the cord from the guitar to the amp, thus the Line 6 wireless system. And there are other wireless systems I’ve seen advertised that are a lot cheaper, but I can’t vouch for the quality.
Allright mon! Gotcha - as I stumble from my practice session to get dinner and not kill myself from getting tangled in the cords - thanks
