Really confused about how to hook up my bands amps to delta 66 w/ pro tools & record?

So the roland v-drums are pre-amped from the headphone jack in the brain and sound fine in pro tools, but I'm confused about the rest.

The bast guitar has a pre-amp in/out.
So when i hook the bass up to the amp, then hook the pre-amp out to pro-tools the signal is too low even at max volume because i guess it's low level and not line level.
This is the same with both guitars as well.

If I run the normal speaker output from any amps into pro-tools, it's an already amped signal and the amplifiers have to be turned down very low otherwise the signal is too strong / loud and is terribly distorted in pro tools.
We can turn them down low to get a cleaner signal, but it's too low to practice with.

I guess we could them up to a pre-amp right? but how would we make sure that the sound in pro tools is carrying the same effects and adjusted tones that the guitar amplifier is set to?

Any help is appreciated, cause I'm a total noob at setting this stuff up.

DO NOT connect the speaker output of your amp to the Delta 66, you could damage it.

What guitar/bass amp are you using? Does it have built-in effects? Are you using FX pedals or processors?

The guitar amp is a vk212 and the bass amp is a tnt 115.

They both have gain switches and normal knob controls.
The guitar amp is using an effects processor like this:
Guitar>amp>preamp out>effects processor>preamp in>built in speaker

Ok, so no more amped output hooked up to the breakout box? See if i was super careful and started with all the levels down, i could raise them to a decent level to match the drums. Only problem is that the waveforms are just COMPLETELY full on all recordings unless he turns his amp down really quiet. Also it doesn't pick up any of his lows it seems like. Just the mids and highs which makes the guitar recording sound like crap.
