What is "Five Star Field Service™" ?

  • This means that when you are touring through Calgary and area, we can meet you on-site at your venue or hotel and service your amps, effects, cabling and guitar electronics. It's like having a road tech make a house call. This service is available for tube amps of all types and covers on site tube testing, re-tubing and biasing, cleaning controls, replacing reverb tanks, replacing speakers and performing general maintenance and repairs.


  • If your amp requires more extensive repair, we'll take it back to our shop or even another repair shop if you prefer.


  • The show must go on! We have Swampdonkey amps available in case you need a loaner to get you through the gig. If you require something else, we'll do our best to get it for you.
