Combo amps vs Cabs, and heads.

Whats better a cab and a head, or a combo amp, is there a huge difference?

A head and combo allows you to easily swap around speakers or amps.

Most cabs are closed back which gives a different sound to a combo which normally is open backed. Which is best depends on what you are doing.

The up side of a combo is that you will usually get better value for money.

i'd say if you can budget it go for a head and cab its an overall fuller sound.

Honestly, it depends on what sound your going for. While some cabs are open back, most are closed back and give you more bass response. Some solid state combos are closed back, but most tube combos are open back (to allow airflow for the tubes).

*metalhedit: The whole part about airflow for the tubes may just be drunken gibberish... makes sense to me right now though...

I believe you are just gibberishing, otherwise heads would also be open back.

Ventilation is critical to tube amps. Show me a tube amp head that is purely closed and I will call it a disaster waiting to happen.

There is ventilation, but they're not exactly open. I guess at that point I'm just kinda splitting hairs.
By ventilation, I meant like that perforated plate deal.

Most tube amp heads are open backed.

I was just hair splitting between perforated sheet over the back and nothing.

I was actually looking at some of that expanded metal for grill cloth, not sure I'd like to have anything really electricy touching it though, I'm one of those what-if kind of people.

There should be nothing live on the outside of the chassis. If there is you got far bigger problems.
even if you have bias probe points on the outside of the chassis, It's nowhere near the grill and recessed.
That stuff on the back of Abbey above makes great speaker grill. It's so open that it's like having nothing there. On the back of an amp it doesn't matter but as a speaker grill, just get it powder coated in whatever finish floats your boat.

I'm not getting any metal cab hardware coated, Hopefully that stuff, along with whatever metal covering I decide on will rust in an ever so attractive manner. What goes on my head I'll probably get finished though, I don't like rust near my power tubes.

Like I said, I'm a what-if guy, To a pretty extreme extent. The whole time I'm on roller coasters I just sit there an analyze the structure for faults because I'm terrified of structures failing whilst on them. I also don't like being near edges because I always fear that I'll trip/get pushed, I don't even go near the guard rail on the second floor of the mall for that reason. I worry alot about that kind of thing. My main worry on that would be that somehow a wire gets crossed and I'm pumping amplifier power into my back covering, and that if I touch it I'll get shocked all to hell.

Well then, I guess it's official, I've been catted. I am now officially over-worried.
