Gabriel-Tech | Chip for main fuse | GDL90

Product Review (submitted on May 12, 2014):

Must say I’m very happy with the GDL90 and it does do what it says, removes ‘smog’, or another layer of ‘grunge’, everything is clearer, easier to hear the separate instruments, harmonies, easier to hear the individual voices within them, etc. …… one of my best upgrades ever.
