I recently bought a Vox AC15CC (with the Wharfedale speaker) and then found a Vox alnico blue speaker for cheap. It sounds amazing! Now I want to add a treble boost for an alternate tone, but... while researching treble boosts (I've never had one), I discovered that they were originally designed for the Normal channel of an AC30. Since the AC15CC is a top boost channel, would a treble boost sound good? Isn't the top boost channel already "treble boosted"? Experienced treble boost users... what do you think? Thanks.
