It's a stupid question I know, it depends what sounds good to the individual, but I have limited experience and need a starting point. I play mostly Teles, mostly single coil but occasional humbuckers. I like full Fender clean tones and when I need it all my drive comes from a TS-9, Big Muff and Jeckyl & Hyde. I currently play through a HR Deville 4x10" which is not bad to my ears, just not great. I'm planning on building 2x10" open and 1x12" closed cabs to run from an AA165 Bassman. As I said I like fender cleans, but I like fuzz and distortion too. Not looking for modern tones pretty much ever. Punk crunch is good, not numetal crunch. I don't know that I need speaker break up. I think I need something that just does what it's told by the amp and pedals. I know I probably want the SPLs of the cabs to match. Guessing the 10"s should be around 3dB less than the 12" so the levels are similar with a pair, although the closed cab will probably mess with that. The 1x12" may end up being open back too. So many choices! I'm a hack, not much of a guitarist in the first place, playing mostly post/proto-punk stuff. I'll probably end up experimenting as I figure out what I like about my setup but in the meantime where do I start? What's worth trying out maybe in the $50 per speaker range? All opinions gratefully received. In the meantime, Happy Friday!
