Some of the instruments we use

Uilleann Pipes
These are also sometimes called 'Union' or Irish pipes. Generally I use a set pitched in D but very occasionally I'll use a C set.

Flute and Whistles
For some tunes I'll use a keyless flute or different whistles.

We have two accordions, one in standard tuning and one tuned to Bb to match Highland bagpipes (its a long story).
Scottish Smallpipes
We use three different pitches at the moment - A,Bb and D.
Northumbrian Smallpipes
We rarely use these but the sets we generally use are pitched in F.

Border pipes
It is very rare that we use these but the set we use are pitched in A.
Highland pipes
