I recently bought a alto saxophone from eBay and was wondering if a repair tech would be able to determine the playing condition of my horn. The problem is I have the horn with a 2 week return option but will not have a mouthpiece, reed, strap, etc. For about a week 1 1/2 due to shipping. Do I need these equipment to have my horn checked completey? I will be going to Sam ash, thanks in advance!
