Sorry but that info is incorrect. Geoff (synth/sampler) is indeed boosting the sound of the French horns but - it's about 80% unmic'ed horn sound and 20% synth. And that's mainly to help it carry up to the box, because from up close those French horns are LOUD. Also Allison has a mic attached to her shako for her solo, it is absolutely not pre recorded, it's simply mic'ed up with a slight amount of reverb. Hope that clears things up! :)
