this mic, for its price range, is unbeatable. I have been using the XVIVE LV2 as instrument mic (instanbul lute / lavta / ethnic acoustic guitars) but it has a high frequency little boost that makes it brittle and fragile as an mic attached to instruments.
and this t.bone lavalier sounds just right: neutral, sensitive enough, small and the cable and connector feel good as their are made from quality plastic and rubber.
if you, like me, are looking for a lavalier to amplify acoustic instruments, specially if using it inside or on sound holes, this mic may be a very good option. use it with a recorder/preamp with low-cut or eq and you have a excellent solution for acoustic instruments amplification.
