Hey there... I recently gave up on my Orange AD30TC for a Vox Heritage AC15 and i'm not in the slightest bit unhappy about it! I love the tone and the new brightness and sparkle that it adds...even with my Les Paul. I did have a question though and thought maybe someone here could help. I've heard tale of some people using an ABY box to run both channels independently and together. I was curious to know if anyone knew how safe this was...and also, if there were any phasing issues? Ideally...I'd love to use the Top Boost channel for mildly dirty/cleanish and then run it WITH the EF86 channel for my drive channel (because it's fantastic!) but keep the top boost running as well for some added sparkle. can anyone offer any help here? Thanks!
