I am currently clearing out a large collection of professional studio gear that I no longer use, ranging from used gems to brand-new unused and box opened equipment. All items are in full working order, some may have some cosmetic imperfections but I will highlight that in the pictures and description. Please check back regularly or view my other listings, as I will be adding many more items soon (microphones, monitors, gadgets, pedals, accessories and more...)
