I have some questions about mixing cab and head brands:
1. Which heads by certain brands pair well with cabs of other brands?
2. How can I know?
3. Are differences significant enough that you should rather stay within the brand of the head?
4. Does it come down to speaker type? Like, does an Orange pair best with any brand that has a Vintage 30 speaker? Not?
5. What info do I need to know before crossing brands?
6. Which brands definitely do NOT mix well?
7. Or... are these stupid questions and it really doesn't matter, i.e. any pairing works?
For example, which cabs of other brands would go well with a Mesa 800 or Orange OB1-500? Would an Ampeg SVT15E work well with either? A Fender Rumble 115? Is the price disparity worth it?
Please don't say, Mesa with Mesa or Orange with Orange. I am curious to know which other brands will be equally good. And it's not a question of budget, it's a question of learning how to do the research, i.e. what to look for when shopping.
Literally most any head will work with most any cab ... but, it will likely be different than the 'next' set-up you try ... unless you have unlimited funds, it is
always a question of budget, especially since you asked, 'Is the price disparity worth it?' ...
You are asking good questions, and yes, some mfr's have a certain type of sound 'built in', but at the same time, features, portability, ease of use, weight, physical size, sealed/ported cabs, and of course price and availability (both to try and acquire) all come into play ...
...
Brand is only one of the components to consider .... I happen to be liking GK heads, as
for me they are a very simple head, with flat generally a point I can start at every time, and quite often adjust very little ... I also happen to be preferring the sound/response of sealed vs ported cabs .... at least that is what I own, but at the same time, I seldomly have a problem finding something useable with a supplied backline, unless it tends to be too 'boomy' and is hard to clean up ...
'How to do the research?' .... try anything and everything you can get your hands on ... it can easily get expensive, but many of us have done it over 30,40,+ years to spread the $$ hit out ... also, your final tonal results are synergistic, meaning a result of everything else that goes involved (bass selection, EQ choices, playing style, type of venue, other instrumentation, etc., etc.) ... and what sounds good to you playing alone , may not work well when playing with others ....
What is it that you like about your 300 watt, ported 115 Laney combo? ... what is it that you dont like? ... what is it that you are tryiing to accomplish with the change to head/cab? .... might be almost more important questions, at least to start with ...
JMHO's ... as always
