Sell Pro Audio & Music Equipment for Cash in Boston, MA

Audio gear is graded by what leaves the output jack, not by how clean the faceplate looks. A scuffed cabinet with a healthy driver grades above a mint one with a rubbing voice coil.

• Powered speakers - cones pressed by hand for coil rub, surrounds checked for rot, then pink noise through woofer and tweeter.
• Mixers - every channel gets signal, not just channel one: gain, EQ, aux sends and fader travel, listening for crackle.
• Microphones - phantom power on, output compared against a reference, listening for hiss or rattle from a dropped capsule.
• Amps and outboard - hum at idle, noise floor with the gain up, and on valve units how it behaves once warm.
• Interfaces and controllers - installed on a laptop so drivers, jog wheels, pads and inputs can be checked in software.

A fault does not end the deal. A dead channel on an eight-channel desk is priced as a repair, not a rejection.

Two identical desks can grade the same on the bench and still be quoted differently, because much of the value sits in the box beside the unit.

• The right power supply - check voltage, current and polarity on the barrel plug; a 9V adapter on a 12V desk tests dead.
• Shockmount and case - a condenser with its spider mount, clip and wooden box is a finished product; loose in a gig bag it is a capsule.
• Rack ears and grilles - missing ears, dented grilles and stripped handles are cheap parts that are slow to source.
• Licenses and dongles - bundled plugin authorizations or controller software still tied to your account need releasing; say so up front.
• Serial and receipt - a readable serial plate and the original invoice settle model year and spec in seconds.

Bring valid photo ID for the paperwork, and say if you would rather take trade credit against something in our inventory.
