Transistor amp outputs are usually regulated by the impedance of their load; a 16 ohm load will only allow the amp to develop about 50% - 60% of the power it will make with an 8 ohm load, which will only develop about 50% -60% of the power that the amp will produce at 4 ohms, and so on.
Tube amps use a transformer to match the load with whatever impedance range the output stage is comfortable operating in, which is why they generally have multiple and switchable taps; to facilitate impedance matching with a variety of cabinets with a variety of impedances.
This is the reason that output transformers exist; it isn't a case of "low end punch and crunch" or any other tonal inflection, it doesn't care what you have in front of the amplifier’s output stage.
Theoretically all of the output taps will put out an identical signal at any impedance, and that signal will be transparent from at least 20 hz - 20Khz. That's pretty much the goal of designing an audio transformer.
However in actuality there are variations from "transparent" and output transformers do generally “color” the signal to some degree, often limiting bass response because of a lack of mass. There is also occasionally slight variations between the different taps themselves, but the purpose of the impedance selector is NOT to provide different tonal options. Its sole function is to keep the output stage performing safely and as it was designed to perform.
Sunns have huge iron and huge bass response, and are by comparison very hi-fi in their performance. This is probably why Sunns have always been, and seem to remain popular with bass players.
I’m not exactly sure what you are talking about, but I’ll try to “get it”. I don’t really understand your tonal descriptions of the various cabinets; and what exactly is an “xlooped-ed Marshall 1960b”?
In all honesty your post reads like just a bunch of buzz words and hyperbole to me, but I admit I don’t know much about the “noise” genre of music so maybe I’m just unenlightened.
I do know this though; NO ONE knows what sounds good to you. Asking for cab advice in a forum probably won’t get you a lot of useful information in your quest for your ultimate “noise” rig; you will probably need to do a little trial and error.
While I can’t personally imagine the rig you describe sounding like anything but atonal crap, maybe that’s your goal tonally. To each his own, and you may well think that my rigs sound like ass. C’est la vie.
Anyway, from my perspective I don’t see anything wrong with your signal chain, if I felt compelled to add a comp to that odd collection of components I’d put it at the end as you describe.
It’s not “my” search engine, just like it’s not “my” forum. I wouldn’t know where to start with building and maintaining an internet forum. That said, I’ve never had any trouble finding what I’m looking for using this site’s search function, and haven’t heard any complaints from others.
How would you improve it?
