I couldn't not include a photo of some LFSys cabs, could I? Pleasingly, there were quite a few present. My thanks to the owners for bringing them along.
I managed to try a few different amps through the cabs. Sean's Gallien-Krueger sounded nice, lean and punchy. I was also very impressed with the Handbox head that @wateroftyne has been praising all these years. Never heard one before, but is sounded really sweet.
