I pulled the trigger on an AC15CC blem yesterday. Assuming they find it in the warehouse and it makes it here I'm already considering swapping out the Vox Wharfdale speaker (well, maybe not immediately). I have a nice Peavey Sheffield 1x12 cab and I'm wondering if the Vox speaker is higher quality/sound than the sheffield. I figure I could put something really nice in the AC15CC, then start using my Peavey cab as a testing ground for speaker swaps starting with the Vox speaker. I don't know how to replace speakers, but it can't be that difficult right? (I can solder ) So what is THE quintessential Vox speaker? Celestion Alnico Blue? Someone is selling a Vox with a Gold in it which might be a nice speaker too. But they are expensive as hell, even used. What are my cheaper alternatives for sweet Voxy chime in the AC15CC for less coin? Let's hear your opinions. EDIT: Is there someone here that does some type of mod's to the AC15CC to make them better, quieter, more reliable, etc...? I thought I remember reading a thread that there are some fairly substanstial improvements that can be made to these amps. Please let me know if you've heard.
