Max out your Boomers® experience with our Sub-Zero™ Boomers® series. GHS Sub-Zero™ Boomers® are Cryogenically treated in a computerized system with liquid nitrogen, taking them down to a temperature of minus 300 degrees Fahrenheit, and then gradually restoring them to room temperature. This treatment improves the dimensional stability of the strings, keeping them in tune, while increasing resistance to corrosion.

would like to see an .0095-.042/.044 set. the older I get, the easier they are to bend. other string companies have seen the light so get on board!

Jonathan Moody

You can easily put a 9.5 set together from the singles that are available. That would be an option, while we see if the demand is there for a packaged version. 

chris w.

So when are you guys going to do a 7 and 8 strings sets of theses?

Jonathan Moody

Hi Chris, thanks for the question! At this point there are no plans for a 7 or 8 string set of the Sub-Zero. Aside from you, I've not fielded any other requests for them. 

michael s.

7 and 8 string sets please.

J.P. S.

Great strings, although I wish GHS would offer them in more sizes such as TNT.

John P.

Best strings I’ve ever used. They last a long time and have just a different feel than the normal boomers.
