This is a completely customized TM Custom 500SL saxophone that we made for a customer. Eric Drake of Saxcraft has fully engraved this horn and it is stunning. The pearls have been replaced with custom brass sleeves, the resonators are MK VI style nylons and the neck is a custom hand bored 500SL copper neck. TM has regulated and made sure this sax is gig ready! If you are looking for a TM Custom at a lower price that has been fully customized than this is a great option!
