First, thanks for all your help in regards to my other thread. I've worked out a really nice deal for a new condition Sunn 300T, which I think will provide what I'm looking for in terms of an amp. That said, I'm now focusing on the cab situation. As mentioned in the other thread, I have an Ampeg HLF 4x10 that, while an excellent set of speakers, simply can't handle the distortion, noise, loops, and all that I push through it. Thus, I'm now in the market for a 4 ohm 1x18 or so that can take the punishment without a volume drop while I use the Ampeg for the highs. If required, I'm prepared to use a poweramp so as to hit the speaker with more watts. Vicenzajay pointed me to Madison Speakers, who I have every intention of checking out, but I also open to other ideas. Aside: I'm also interested in pickups that would reduce noise from my American Standard Jazz while maintaining the aggresive sound. The noise isn't much of a big deal when clean, but with the gain levels I use it can become a complete nightmare, particularly while recording. Thanks for all your help!
