I bought it in April 2024, I used it at a lot of concerts, rehearsals with the band, ...
It is very reliable. I have never noticed any problems with signal transmission, no dropouts, no noise, even when I run around the stage or among the audience. It does not negatively affect the signal coming from the instrument.
However, I have 2 very small complaints about the control:
1) The gain setting on the transmitter does not have a very large range, especially downwards. With one of my guitars (a baritone guitar with an SD Nazgul in it), I have to set the gain on the transmitter to the lowest value. If I had a slightly stronger pickup (e.g. an SD Invader), I suspect it might start to clip.
2) There is no possibility to synchronize the transmitter and receiver (using an infrared port or something). I look for free frequency bands every time I arrive at the venue and unpack my things. Having to open the transmitter and click through the channels is a bit frustrating, even if it is just a 2-minute job.
