There's a lot of speculation that can lead to reputation on a forum like this.
I do not remember any discussion/fight like sturob mentions and I have been reading these boards regularly for over 5 years now (it looks like a long time in print
can you provide a link to the discussion?
Problem is that a remark like that can come up again the next time Cotter flutes are discussed. Similar thing happened with discussions/rumours about Sam Murray. Very unfortunate indeed.
Whatever the case in the interwebworld, Eamonn is a respected flutemaker, performer and teacher of Irish Traditional music - at least in Ireland/Europe like MArkus mentioned.
He might not be that known outside Europe because he doesn't have a website. I don't think that's his cup of tea. He has an email adress, but I don't think he uses it
He doesn't market his flute like some other makers, and therefor his flutes are not credited on as many recordings. All I remember is that Harry Bradley played a Cotter Eb on his 'Horseshoe Bends' CD and Gary Hastings plays a Cotter (also Eb?) on Slan le Loch Eirne.
There are more flootplayers that do not record than there are those that do (etc etc)
I have had my 6-key Cotter flute for 3 years now and do not plan to part with it. When ordering I wanted a flute from a European (EU) maker to prevent high import taxes, a reasonable waiting time (less than a year at the time) and a quality instrument that would last me for many years to come.
The more experienced flute players here have commented very positively about the flute. One of them referred to it as a great flute and excellent tool for making irish music.
By no means 'just a beginners flute'.
Here ends my rant/ramble,
