As part of my setup process I will put on a new set of D'Addario J74 Medium Gauge Phosphor Bronze strings. For an upgrade charge you can choose from
I highly recommend Wegen hand-made mandolin picks. They are imported them from the Netherlands and once of the best sounding picks I've ever heard. At a minimum the Wegen 1.4 mm Triangle and the 1.5mm rounded traditional mandolin shaped pick are worth trying as they give you different tone and playability.
The Mando Shop offers a nice soft leather strap called the Softy Mandolin Strap. It's very comfortable. If you are buying an A style mandolin and want to use a strap, I suggest you have me install a strap button on the underside of the neck near where it joins the body. I find using a second strap button to be more comfortable than connecting the strap to the headstock. The other end attaches to the strap button on the bottom of the mandolin.
The Snark Tuner clips on to the mandolin headstock and tunes based on vibration from the mandolin. It works great in a jam session.
The nicely finished wood maple mandolin string winder we recommend that is hand-made specifically for the tuners on a mandolin. The string winder used for a guitar doesn't work well on mandolins because the head of the winder i too big and hits the other tuning keys when being wound on a mandolin. If you plan to change your own strings then this is an essential tool well worth the investment.
The laminated chord chart is a handy way to have mandolin chords easily accessible. It's durable and rigid enough to lean nicely against something for easy viewing.
A microfiber polish cloth to wipe your mandolin clean before putting it away is the best care you can give the finish of your new mandolin.
The Oasis Mandolin Humidifier is hand-crafted in America. Oasis® humidifiers are the best solution to the challenge of fine wooden instrument humidification. An effective, easy-to-use humidifier is good for your instrument and far less expensive than costly repairs.
You can upgrade your mandolin strings to one of these options, D'Addario EXP74 Medium Gauge Coated Phosphor Bronze Strings, D'Addario EXP74CM Custom Medium Gauge Coated Phosphor Bronze Strings (Heavier E and A strings), D'Addario EFW74 Flatwound Stainless Steel Strings, Elixir Nanoweb Medium Gauge Coated Strings or Elixir Nanoweb Light Gauge Coated Strings.
If you want to plug in and play through an amp, the K&K Twin Internal mandolin pickup is a very good solution. The pickup is installed on the inside of the mandolin with the 1/4 phone jack replacing the strap button.
Calton Cases will build a custom mandolin case specifically for you and your mandolin.
