The perfect preamp
The tone capsule saved my gig! The sound engineer refused to DI my Helix and insisted I run through a keyboard amp he mic’d up already. Short story shorter, I dialed in to a great tone with my tone capsule. The two mids and a bass are perfect, targeting the exact frequencies I need to modify on the fly. Also, the Q is wonderful. Cuts and boosts just sound right. I struggle to replicate them on a parametric EQ, and am thankful I have a tone capsule in my bass.
With these tones I can sculpt my sound really well, making my Thunderbird closer to a P-bass or Stingray. It will never be THE SAME, but it will be in close enough ball park for the audience not to care.
