Ireland's Newest Guitar & Amp Maintenance Service.

Excellent Results. Affordable Rates. Right in the heart of Sligo.


I had an M-Audio Keyboard with a broken USB connector. The computer wouldn't connect to it anymore. Shane repaired all the damage and got it going again. He also fixed a vintage omnichord Keyboard for me. Thanks Shane!

You couldn’t walk into his workshop and not be impressed by his use of space and the meticulous ordering and hanging of parts and equipment. And that adds significantly to the atmosphere of trust that the above factors have created, because If the inside of my speaker looks half as tidy as Shane’s workshop does, I have a feeling it will last long after it should have packed it in.

I had an SE Electronics tube condenser mic in need of repair. There had been significant noise in the signal. Shane sorted it out. Great service to have in Sligo.
