Yes the preamp should be pretty much verbatim Top Boost style and the eq certainly works that way though it shows how the PI and EL84 PP PA is a key part of the Vox sound. the C1 certainly has a Voxy vibe but an AC15 would definitely get you closer.
/for people who play at home I can't recommend a Torpedo Captor or equivalent enough - pair it with a head if space is an issue and you have a real sounding/feeling amp which you can also take to a practice room or gig and records effortlessly.
AC4C1. Is that the Blue one with Top Boost?
