So, let's try to get an actual decision to happen here. I believe that the policy for equipment questions should be changed.
At the very least I would like to see the wording for reasons to close changed:
Questions seeking recommendations for equipment are off-topic because they tend to become obsolete quickly. Instead, describe your situation and the specific problem you're trying to solve.
Music equipment does not become obsolete quickly. It gives the impression that this site isn't in tune with its subject. This is something that could be changed today, the reason could be whatever that is more correct. (I realize that it's the questions that become obsolete in the quoted statement, but I assume that is due to the obsolescence of the equipment...).
What I'd really like to see though, is that the policy is changed. Equipment is a big part of musicianship, and it quickly becomes a jungle. We should stress that questions about what brand to purchase are not allowed, but questions about what to look for when purchasing a type of equipment are good.
We do allow the latter types of questions already, but sometimes trigger happy people use the blanket reason above to shut down questions that are, or could be made general.
Update 20140925:
The decision is to use the wording in https://music.meta.stackexchange.com/a/912/8682. I would mark this as answered, but the new text isn't available when closing questions as off topic. Might still be in some moderator review queue.
Update 20141212:
The text is updated, but not exactly as the suggestion.
The current text:
Questions seeking recommendations for specific equipment are off-topic, because they are primarily opinion based. Instead, describe the required function and setting in which the equipment will be used, and ask what you should look for to achieve that.
The suggestion:
Questions seeking recommendations for specific brands of equipment are off-topic, because they are primarily opinion based. Instead, describe the required function, and setting in which the equipment will be used.
I think the "specific equipment" is problematic. It's different from "specific brands of equipment". Don't know if it's intentional. We should allow questions about specific equipment...
