I've consigned items with them and some items I was surprised how much I got and others a bit disappointed. You can get more doing it yourself on USAudiomart since they have no fees. I have used TMR because they are easy to work with and take the hassle of dealing with byers out of it.
Selling gear with TMR
I’m at the point of wanting to sell some gear and am seeking any experiences of selling with The Music Room. Did it make things easier? Did you get what you thought was a reasonable offer? Other benefits or detriments you might share?
