I just wanted to put in writting my appreciation for everything your company has done for me recently. The replacement for my 664 mixer arrived today and is working perfectly. Please pass on my thanks to Matt for his patience, expert help and the guidance he has provided despite me phoning, in a panic, from various locations around the world. Thanks to you all for going beyond the call of duty, the level of service has been absolutely fantastic!
Full control over your performance – everywhere, every day. The G4 In-Ear Monitoring Sets make your gig an extraordinary experience – not just for your audience, but also for you!
