Bought a GB Shuttle 600 210T back in July. Long story short, I will be leaving my SVT rig at home more often now; especially when I have to carry my own gear. I most recently used it for 10 shows in 9 days in Sturgis, SD during bike week and it performed like a champ. Miked up and DI connected to the back of the amp, everyone loved the sound. Keep in mind that we had full production with massive FOH subs so I didn't need to provide the low end for the venue. And no, I didn't need any bass in my wedge monitor; stage volume of the GB was plenty. I play in a classic rock band against 2 guitarists both playing 2x12 tube amps along with a hard hitting drummer. They hate me at the end of the night when I can put my gig-bag on my back, one-arm my 41 pound amp, and walk away with a drink in my hand.
