Hi, daughter graduated Seaholm marching band a decade ago and we're taking over her room.
Used Alto Sax - not museum quality - Perfect Seaholm or Groves quality.
I replaced some pads years ago and they all look functional. Cork is 'good enough' for a season. Case could last a while more longer.
If you want to test it out, bring a mouth piece or a reed - I don't have reeds. if you want me to tune any of the movement, just ask.
If you don't know instruments, the YAS 23 is the workhouse of every band in the world. Don't buy an expensive sax for marching band.
