Willie Nelson’s guitar.
I’ve loved this instrument since the first time I saw a pin-up of it in my guitar magazine as a teenager. As craggy, charismatic and melodic as the man. It is covered in inscriptions from other musicians and friends from across the decades. Also, you can’t quite see it here, but it doesn’t have a pick guard, so there is a second sound hole worn right through the wood at that spot. Magic.
