Tony the right hand does quite a bit to make the rythmic buzzing sound, but you can play without buzzing
I sometimes think of the gurdy as a one string guitar you have to go up and down alot
Keep an eye on the forum for a secondhand instrument, or look on eBay, or get your name down on a makers waiting list...the time does go quicker than you think, plus it gives you time to save up! Incidentally I used to have one of Chris Allen's Symphonies, it was an excellent instrument.
Simon Wascher has a list of makers here: http://drehleierwiki.a.wiki-site.com/in ... umentenbau
The Gurdy festival is in May, it's a good place to see/try/hear alot of instruments.
