Superlux PRA-383D XLR

I have been using three of these mounted on my accordion for about six years and they are still going strong. They have taken a lot of abuse over the years rolling around in the bottom of my accordion case. The packpack box is very sturdy, almost a little unnecessarily heavy though!
To the best of my knowledge the sound quality is very good and I haven't had too much problems with feedback.
The lead to the microphone capsule on one of my units needed top be resoldered after a few years but as I said, they were getting a lot of abuse.
The backpack has a mute switch which is very useful and doesn't pop when switched on. The battery life when not using phantom power is also extremely good. I usually use phantom power but I found that the batteries don't discharge if they're left in all the time so there was always battery power available for the gigs where I needed them.
If I had one criticism it would be that the battery covers are prone to breaking and then they won't stay on properly. They can be taped on but that's annoying if you need to change the battery in a hurry. This is only a cosmetic thing though as the batteries stay in perfectly well without the cover!

Does what it says on the tin! Good bit of kit with big volume and nice tone. Uses mini xlr and is compatible with AKG systems or the t.bone wireless set ups. Only thing missing is an LED to remind you that it's on and I can't work out why the on off button has two on positions as the instructions are in Klingon! and very brief. It has no additional volume control but it's set to give maximum gain/output and the single battery seems to last for ages! The power pack is of heavy metal construction but it's not too heavy to stick in your pocket although it does have a clip. Tough bit of kit and practically bullet proo! I'm actually using the microphone with my tbone wireless transmitter pack because this mic has more power than my AKG bug mic. You can also simply add a mini XLR to 6.3mm Jack to the power pack and DI guitars etc. So, it might be low on features but it packs a big punch.
