I almost certainly am not going to do it myself. Likely I will have my band teacher look at it first but since it is currently summer vacation for me I will not be able to do that at the moment. Currently my instrument is very playable even in its unstable low register, and for the moment I will continue using it as is until I can get repairs.Pads are made in 0.5mm diameter increments. The thing to watch is pad thickness, most beginners miss this. If you're going to do the work yourself, get a copy of Stephen Howard's Haynes Saxophone Manual before you start. It's worth every penny, and more.
