So long as your Guitar's pickup wiring does not use the pull-up resistor connected to the ring wiring method, you should be okay. From Line 6's pdf: [begin Quote] There are two remedies to this situation. The first would be to rewire the guitar jack, reversing the connections to the sleeve and the ring. This should only be attempted by a qualified service technician to ensure that no damage to the guitar occurs. If this wiring is reversed, there will be no change in the guitar’s operation, and the G10T will function with it normally. The second solution would be to use a mono plug adapter or cable, as described later in this document. Some acoustic guitars with active electronics also include processors, and in some cases, they use a more sophisticated method for turning its power on and off with a TRS jack. For example, some have a pull-up resistor attached to the ring of the jack, and turn on the power when it senses that the ring is connected to ground (as would occur if a TS plug was inserted). This configuration will not work with the G10T, since it will sense the voltage on the ring and assume that it is connected to the receiver for charging, and the guitar would not turn on since the ring is not connected to ground. The solution in this situation is to use a mono plug adapter or cable. Lastly, some guitars have two signals, such as a piezo pickup and magnetic pickups, and will connect one of the pickups to the ring and the other to the tip. Although only the pickup connected to the tip will be heard, the G10T will normally work with this type of guitar, but if not, the solution once again would be a mono plug adapter or cable.

Adiaz7531, Yes. At least we're each finding the same firmware behavior. This should be an easy corrective patch. The power off workaround - for the time being - of removing, then, reinserting the Transmitter bug into the base, isn't too horribly inconvenient. However, for those who don't know about it, the inconsistent behavior can be disconcerting.

I discovered a quirk with the firmware! The Transmitter conveniently goes into power saving standby mode after 4 minutes of inactivity (no audio) while plugged into an instrument. However, the firmware neither responded the same when left plugged in the base and the power was turned off, nor, was the firmware consistent! In one case, the Transmitter did shut off in about 20 mins. In another case, it began blinking green at the power off plus 20 minute point, and kept blinking green for another 45 minutes! At this point I unplugged, then reinserted the Transmitter to trigger the 4 minute shut down mode. When plugged into the energized base unit, the Transmitter always begins recharging. Line 6 should update the firmware. The User Guide mentions the USB can be used for updating.

After hesitating for several weeks, I purchased a Line 6 Relay G10 Friday (July 22) from Guitar Center. It is quite impressive! Very easy to use, compact, and sounds terrific! It is small, charges quickly, provides decent range, and seems well constructed. I used it extensively over the weekend. About 5 hrs Friday night, nearly all day (10+ hrs with several recharges) Saturday, and for about 7 hrs Sunday. All using 6 guitars without a problem. The sound and signal quality were crystal clear. I found no audible difference compared to using an instrument cable, It provided a rock solid 50' line-of-sight range. I did not try the balanced XLR jack. Before buying, I was concerned that the Transmitter, protruding from the side jack of my Les Paul, would interfere with resting the guitar upright leaned back against a couch or placed in any of my guitar stands. Fortunately, this all worked fine! Only when seated on the couch, playing the Les Paul, did I need to be cautiously aware of the Transmitter. Even then it was not as much of a protrusion problem as I had initially thought. When plugged into the Sheraton-II Pro (top jack) the Transmitter visibly towers above the guitar, but is out of the way while playing. For both of the above fitments, it still seems that a 90° angled plug G10 version or adapter would be ideal. I also bought a 3rd Party (LiveWire) angled 1/4" TS Female to Male adapter, however, it lacks the Relay G10's convenient collar switch that prevents pops, clicks, hum, etc. from being transmitted when unplugged from the guitar. If I don't find it useful, I'll return the adapter. Perhaps, Line 6 may introduce a 90° G10 version or a switch equipped adapter. On my Strat, the G10 fits nicely in the cradled jack plate. As I do not have the vibrato bar installed, there is no issue with the G10 impeding free positioning of the vibrato bar (as some reports depict). The Transmitter's sensor switch automatically disconnects the signal when the unit is unplugged from the guitar. The signal resumes promptly when reinserted. Best clear signal channel selection is done when the Transmitter is plugged into the base. The Transmitter's LCD and base's illuminated halo indicates the respective status for charging, standby, channel lock, and low power. The Transmitter comes partially charged so, charging to a full charge took less than an hour. When inserted into the Receiver/Charging Base, the Transmitter's LED blinks green indicating there is more than 30 minutes of performance in the Transmitter. When the LED reaches steady green the Transmitter is fully charged. The Transmitter is rated for 8 hours of use and 200 hours standby. After 5 hours of use, I put the Transmitter back into the Receiver/Charging Base and it was back to solid green in less than an hour. I did discover one quirk with the firmware! The Transmitter conveniently goes into power saving standby mode after 4 minutes of inactivity (no audio) while plugged into an instrument. However, the firmware neither responded the same when left plugged in the base and the power was turned off, nor was the firmware consistent! In one case, it did shut off in about 20 mins. In another case, it began blinking green at the power off plus 20 minute point, and kept blinking green for another 40 minutes, at which point I unplugged then reinserted the transmitter to trigger the 4 minute shut down mode. When plugged into the energized base unit, the Transmitter always begins recharging. Line 6 should update the firmware. The User Guide mentions the USB can be used for updating. The base unit comfortably sits atop my amp, and must be powered by a USB source (5v, 1Amp). The included charger block comes with easily interchangeable plug plates to accomodate various worlwide territories. Alternatively, any smaller (physically) sized USB power supply (of rated output) or a USB battery pack will suffice. I used a high capacity USB battery pack to power the Relay G10 this weekend while also using my battery powered Yamaha THR10C, a terrific setup! I did find that the base's USB jack seemed a bit feeble. It did not exude the same rugged durable feel when connecting the USB cable as any of the other jacks on the product. Sitting atop my 2x12 or 1x2 amps it is not too exposed, however, on a pedal board or if unplugged and replugged frequently this could be a point of failure. Time will tell.

Just bought a Relay G10 from Guitar Center Friday. I presume this is one of the latest production units. I use South Creek Audio Cables either in 10' or 20' lengths, depending on my need. In some switching scenarios, I have used a 20' plus a 10'. Compared to using the cables, I notice no audible degradation with the Relay G10. I'm using several Les Pauls and a Sheraton-II Pro all with ProBuckers. Also, have a Custom Strat with Fender Vintage Noisless Pickups. These are fed to Fender Mustang IV v.2, Fender Mustang III v.2, and Yamaha THR10C amps.

The Line 6 USB charger adapter provided with the G10 Relay is rated at 5v, 1A (1000mah). If you use another USB charger or power source such as may have been provided with an older smartphone, a Bluetooth device, or a computer USB hub connection, etc., you must assure that it is meets this power requirement. Some such USB charge sources only provide 5v at 500mah, 750mah, or 800mah. Some are even less! I have one from a Plantronics bluetooth ear bud that only provides 350mah. I would not bother to waste the effort to try such with the Relay G10.
