Bi amping ampeg cab question

So I've been wanting to try bi amping my 4003 for awhile now. I currently run a rig with a VB-2 through an ampeg 810. I was wondering if I were to obtain a guitar head if I could bi amp both of them through the same 810. Due to the fact that the 810 cab can run the 410 halves separately (in stereo I believe). Would I gain anything out of this or would I need to use a guitar cab as well to really make the most out of it.

The vb-2 shouldn't have any issues staying clean. Plus I wouldn't be able to push it as hard through a 410 anyway. I'll find a place that has a good return policy for the guitar head.

So if my 810 is taking a 4 ohm load in mono, will I need to be sending an 8 ohm load to the two halves?

Most 410's are 4 ohm and will be 8 ohm per half, that is each 410 "half cab" is 8 ohms and the entire cab is 4 ohms when used together. If you are getting PA support you will now need to mic both halves and use 2 input channels on the FOH mixing board...

"sending an 8 ohm load" is a poor choice of words, your stereo amp channels will need to support/work with an 8 ohm load applied to them (most do...). Another way to say this is your stereo amp channels will see an 8 ohm load with half of an 810 cab connected to each channel.

This is the Ric-O-Sound thing where you have bridge and neck pickups going to separate amps. Not "biamping" in the traditional sense.


OP, you could run a separate amp into each half of your 810, provided it is wired like two completely separate, individual 410's when you do that, and provided both amps have an 8ohm output tap (assuming tube amps).

Could also do it with one, true 2-preamp channel amp, all into the one cab

It might make sense to just get a little 1x10 or 1x12 guitar combo instead of a head. Run the Peavey into the Ampeg and throw the combo on top for the color.

I was thinking of doing this too. But I'm not sure the volume would be enough to match.

As for what I said earlier. What I'm trying to understand is: if I run my amp at 4 ohms into my 810. Would the two amps put into the separate halves of the 810 need to be set at 8 ohms?

My 810 is the Heritage model. There are two options with that cab: run the top four speakers @ 8 ohms or all 8 speakers at 4 ohms. Yours may be different - but it should say what the inputs do on the jack plate.

Running it as two 8 ohm 410 cabs will probably take some modding - in which case I would consider using less speakers for the guitar amp.

Oh I didn't know it was just the top 410 that was usable separate. I thought you could run each half independently or in stereo. Mine has 3 jacks on the back

Just an update, I'll be picking up a guitar amp locally tomorrow to try it out. I was just wanting to make sure that I need to run the amps at 8ohms when they are plugged into the separated 410s correct? Because I run my regular amp at 4ohms into the mono 810e.
