Bass Wireless System: Line 6 Relay G50 

Awesome stuff! About the transmitter: my friend uses the rack unit G90, but the transmitter is the same, TBP12. He's got a lifehack for the battery compartment: he puts a very short loop of elastic band (like the one used on underwear xD) onto the transmitter, so the battery compartment wouldn't open even when the clip is broken :D And he also has unscrewed the metal clip and puts the transmitter into a pouch (Richter, I believe; around 15€ on Thomann) attached to his strap. I personally use the G30 with TBP06 transmitter, and the 06 has been a mighty PITA: the metal clip broke off almost immediately, so I went for a t-bone pouch (7€ on Thomann) instead. Then the battery compartment door started to give me hard time, the plastic dots holding the metallic plate in place fell off, and the compartment started to open when it wants. Tried to fix it with epoxy two times, no help whatsoever. A workaround was to close the pouch strap so tight that it would hold the compartment together, but I guess I will resort to the elastic band loops here :) The positive thing about 06 is that it uses an ordinary jack for cable connection. I still had to make my own cable because I needed angled jack on the guitar side of cable. And I recommend using the rechargeable batteries: they last longer, and you can recharge them :) Just get yourself two pairs and mark one of the pairs so that you wouldn't mix them

Is the sound good and not interrupted? How many hours can I use it when charging?

This is a great video. Have you ever done a comparison between the wireless and an actual lead? I've used a Shure GLXD16 for several years now and decided to do a comparison in my studio. Listening critically I could tell there was some signal loss around 30hz and 4khz when using the wireless. I've never had a problem with the wireless sound with all the gigs I've done on it but it was surprising to compare it with a lead. I'll have to put it into a YT video one of these days.

I found a replacement chord right away on ebay, and haven't needed another one since.

I've used the rack mount version for years and they work great. I have added a neutrik silent plug You could I suppose create a minixlr to 1/4 female (then use a regular 1/4 to 1/4) to reduce wear on the xlr but maybe that's a bit too much hassle
