Beautiful shot from @bmitchner 🙌 #gkallday #gallienkrueger #gkamps #Repost @bmitchner ・・・ So excited; I have decided to team up with Gallien-Krueger and welcome this bad boy to my set up (I am totally not paid or sponsored in any way by GK); I love this Made In USA brand, and feel that this enhances and helps produce the best quality sound that I want. In other words “I’m ‘bout to make this thing sang!” 🎶🎸🤘🏼
