I use this case with Solar 7-string guitar and it works well with it.
At first this case was a little bit too tight fit, but fortunately cushion material kind off molded for my guitar, so now it is a perfect fit.
There is plenty of room for accessories too. Im usually carrying 6m and 3m cables, guitarstrap, NUX tuningpedal and powercable, littlebit of maintenance- tools etc.
It feels well built and robust for carrying your instrument without worries, but if you have to fly, proper flightcase could be better option. Though, I cant be sure, if this case would still make it.
Overall, I am quite pleased with this.
