I just purchased a VOX AC100 CPH head and a VOX AD412 CABINET. links: http://www.voxshowroom.com/uk/amp/ad412.html http://www.voxshowroom.com/uk/amp/ac100cph.html The cab is stock. what I want to know is I have used it a few times without incident. I dont play with a lot of low end anyway but are there 12" speakers I could put in that would be better at handling the bass frequency? I dont want to blow these speakers and I LOVE VOX tones. Basses that are used are DAN ARMSTRONG, HOFNER CAVERN, RICKENBACKER 4001.
