“I have a hard time remembering all the times I had Markus work on my bass guitars with incredible results. Whether your instrument is brand new and in need of proper setup to fit your needs or a derelict piece of lumber in severe need of salvation – Markus will make it look, feel and play as if it was straight from the factory and, more often than not, even better! Perhaps what’s even more impressive is Markus’s keen ear and his treatment of customers which makes him an absolute bliss to work with. He’ll walk that extra mile to make sure you are satisfied with the improvements he has done.”

“Do you have issues with your instruments or do you want to get back to that feeling your instrument had when it was new? In that case I wholeheartedly recommend that you bring it to Markus at Heidarsson Guitars. He provides excellent service and incredible attention for what instruments need. With Markus’ competency and feel for instruments your guitar or bass will receive exactly what it needs to be in top condition again”

“I left my Gibson 100th Anniversary to Heidarsson in a nonfunctional state and he returned her as one of the nicest instruments I have ever owned. He asked me what I was looking for and suggested all these clever upgrades that turned out to be fantastic ideas. I recommend Heidarsson to every string-player I know.”

“I met Markus as the guitar tech at the Abyss festival. Our band was performing late on the evening of the first night of the festival. He not only replaced my strings for me before the performance, but he also cleaned the pots, knobs, and fretboard for me. He also touched up the pickups and hardware going above and beyond what I expected. The guitar was all set up nicely and plays better than it has in a while. It is a ‘78 Gibson Les Paul custom. Markus is a true pro and I would recommend him to any guitar player!”

“Markus was incredibly professional and helpful. Even though we couldn't bring our own guitars Markus made sure we had everything set up to our specific specs and helped us deliver a set without any worry of gear failing. If only it was always like this.”

“My Ibanez SRFF805 is a great instrument but lacked something in the sound. So seven days before going into the studio I decided to switch the preamp to a Darkglass Tone Capsule, tried it myself first but failed. I checked with my friends after a good guitar tech and I got Markus' number. Markus answered that he could fix my bass before we started in the studio. Markus is a great guy, always greets you with a smile and has a good understanding of instruments.

The day before the studio I went to Markus to pick up my bass. With the new preamp installed, straightened and polished neck and a string action to die for.  So overall rating of Markus' work is five stars out of five. Quick, easy to talk to, phenomenal work. Do you need help with your musical instrument Mr. Heidarsson will fix it!”

“Markus will work on your guitar with a lot of knowledge and care. I left him my Les Paul for help with faulty electronics and for a service. I received the guitar back brought to its full potential, perfectly set up and shiny clean too!

If you want to give your instrument new life you should leave it to Heidarsson Guitars!”
