I've got a Goodsell 5 on it's way to me and was wondering what you Goodsell owners have in your amps. I know that he's only made 19 of these 5's though. I'm thinking of replacing the speaker with a Celestion Blue that I have sitting around. Since the amp is an EL84 amp and I've heard it has an AC15 kind of vibe maybe the Blue would lend itself to that kind of tone. What have you guys tried in your Goodsells?
