I want the black one you have pictures a wl-2O ?** A: The WL20L (Grey receiver) is more suited to acoustic instruments with active preamps . L=low impedance. **Q: Will the 20L work with a passive piezo pickup having a high impedance output. Can it work with the charger connected.** A: Hi it works with a piezo pickup on my electric violin but interestingly is a bit lively. I have never tried using whilst main is plugged in. **Q: I think I’ve mistakenly bought the wrong version as all my guitars have battery preamps fitted - am I better off with the L version?** A: Do the ones you have work? If they do, then keep them. For me, they worked well on all of my guitars that have both active and passive systems with magnetic pick ups but didn’t work at all with instruments with active piezo pick ups (loud buzzing noise). You will just have to try them on every combination you have. I wanted them for use principally on my Godin encore nylon thru a Roland ac60 and they did not work (active/piezo) so sent them back; all other combinations (fender, Gibson, status graphite, wal and others) were ok, including basses, thru many different amps). **Q: The dimensions (4 x 12 x 16 cm) and photos suggest it's fairly chunky. How convenient specifically is the transmitter when plugged into the guitar?** A: Hi and thanks for noticing this error in the specs. The correct dimensions of the transmitter are 87mm(w) x 22mm(d) x 36mm(h) and it weighs just 43g or 2oz. The units are really quite small. The width measurement includes the jack plug which is inserted inside your guitar's jack socket.
