Please note:  If you are waiting on an order from us… we are hoping to resume shipments by the end of January, but are waiting for the estate of our founder to be settled.
Feel free to contact us if you’d like an update on your order, or to request a refund.

It is with profound sadness that we share the loss of our friend, brother and founder of MJC Ironworks, Michael Connolly, after a lengthy battle with cancer.

Typical of Mike – he fought it right to the end, and never stopped making strings.

Michael LOVED musicians. The telephone number on MJC’s website and business cards was his personal number. He was never too busy to take a call from any artist, just to chat with them, find out what they were doing, and share a love of music.

He spent a lifetime in the string industry, before deciding to gather us friends and start making his own strings – which are loved by all who use them. It was a dream we shared with him, and are proud that we could walk that road with him as long as we did.

Our love and deepest condolences go out to Mike’s family, his friends, and this huge community of musicians who loved him.

The future of MJC Ironworks is uncertain right now… we’ll have an update on that in the weeks to come. But just for now…

We love you, Mike… you will always be missed, and never forgotten.

Why we’re better… and why it really matters.

There are a bunch of string companies out there… but we’re different.

Experience matters… and we’ve got a boatload.

Not just any old yahoo can make great strings.
