The KM1200 (Kick mic) is surprisingly good on toms/congas and bongos
The TM1200 (Toms mics) needs lots of Gain to attain usable levels, their internal noise becomes audible once the level is good. They are simply not usable.
The CM1200 (Overheads) need also lot of Gain (compared to any other condensers I own) Rather Middish with lack of body. OK for a high-hat, but not for overheads.
All in all, I am happy with the price I paid .
I will keep the the Kick mic and the two little condensers.
