what's up dudes. i have a peavey studio pro, i like it, sounds great. i plan on using a stack down the road, and i was thinking ill get the cab first and use the peavey whilst saving up for the head. my questions are:

1. there is no "speaker out" on the back of the amp, there's a "pre amp out", that's the same thing right?

2. its at 8 ohms, so it'll run at 2 for each speaker if hooked up to a 4x12? is that safe?

3. if i take the amp out of the combo and dont put in an enclosure, just duct tape it punk style, are there any dangers other than it looking like crapola?

thanks fellas!
