Wasn't sure what to expect from this, I'm using a Hohner Bravo III 72 bass accordion and in the past I'd used dynamic mics like sm58 gaffer taped to the grill or on stands. Also I'd tried using a live condenser instrument mic on a stand. The ACM-01 blows anything else I'd tried out of the water! Very good.

Using Live :
Loads of gain before I got any feedback in a live band setting, and the tone is excellent. The mics must have been chosen to get the right kind of tone, nice bass. Easy to install - very pleased.

Practicality :
It's not as convenient as an internal system, but the advantage is if I change accordion later on I can still use this mic system on the new one.
I worried the bass lead would get in the way, but actually it looks very neat. I have not taken it off the accordion since I attached it. So the bass lead, is not even in the way when it's in the case.

Build quality :
Build quality is good, look closely at the photos and that is exactly how it comes. Solidly put together in a metal box. Leads etc seem good quality.

Overall opinion :
Miking the accordion has been a big hassle as I play live a lot. This has solved the problem, I'm very happy and wish I'd got it earlier!

I tried many ways to make the accordion sound good and it seemed almost impossible, mainly the bass part.
As we have no bassplayer in the band, the accordion had to work also as a lead bass in the left hand, but this was the first time it really worked like it should. Very nice bass sound.
The melody part sound is also a nice surprise. Two microphones mean, that the ballance between octaves is perfect, you can hear it almost like it was accoustic sound of the instrument, I enjoyed it much.
The installation was like 10 minutes or less, one does not need to be an accordion specialist to install it properly.
A bigger challenge was finding the best place for the bass mic, one have to try more different places, as it depends on the type of the instrument.
And the best part was -> no feedback during the concert, I was more then 5 decibels bellow the feedback point in ff (fortissimo), so absolutely no stress at all, one can concentrate only on music.
All I can say is, the producers of this product knew what and how they did and they did well.
