Bass Rig in stereo?

[crguti]

I have been using an Ashdown ABM500 head with ABM210T cab. I recently added a Hartke HA3500 head which very soon will be accompanied with another ABM210T cab.
I'm planning to connect each head to an independent 2x10" cab, thus I can run both amps in stereo.
I'll feed both amps using my TCE Flashback pedal which has 2 outputs.

Someone has done this?
How do I know that both amps are in phase?

for true stereo, you need a different signal to each channel. yours will be dual mono. (unless you are running stereo effects/reverb). if they are out of phase, it will sound thin when listening to both speakers in the middle of them, and it will get bassier when you move to one side.

The 2 outputs of the TCE Flashback are in stereo, so it won't be dual mono, unless isn't switched on.
I'm wondering now, how would it be better to run a stereo rig?... ... a chorus stereo pedal, or a delay pedal with a very small amount of delay?
I'm ordering the cab right now, so probably on Friday I will be able to test my stereo bass rig.

I've run stereo rigs with two identical amps (or nearly identical...sometimes one amp has more power but same pre-amp circuit) and idenitcal matching cabs. Usually, I have the rig set for either wet/dry OR all low + clean on amp and middy + overdrive on the other amp. It's best to use a splitter with isolation transformers to avoid noisy ground loops. Without that, it's a crapshoot depending on the grounding of the wall outlets used.

With non-matching rigs, you'll want to NOT have frequency overlap between them, however, or else you will at least have at least some phase issues.

Are you specifically doing it for the stereo effect or do you just require the extra power of a head for each cab, in which case it would be better to run a line-out from your prefered amp into the power section of the second amp...

^ yep, only for the stereo effect. Because right now I don't need the power of 2 heads together.

This is really as artistic a call as it gets. No one is going to be able to tell you what your sound is but you

If you want an acoustic delay, you can run the same signal to both cabs and set one up farther away. Every foot is about 1 ms delay. You'll probably want about 20-500ms.

Actually i don't want an acoustic delay, only a stereo effect. Probably a stereo chorus pedal will fit better.

The typical easy way of generating a psuedo stereo signal is to delay the mono, split the delayed signal into two, invert one of those, then sum each those with the dry signal at some chosen mix level. I had a multifunction delay unit that this function as one of its choices. The chorus will give you a sweeping function, this will not. I don't know how much effect you're going to get out of this on a bass signal. The delay will have the most effect on the higher frequencies where the period is comparable to the delay time. Get a cheap delay box and try it. I used an old Midiverb.

sounds like a recipe for chorused string and pick noise over mud to me but what they hey! as an experiment maybe it'll be cool.

I often run stereo / dual mono but I do that to spread my cabs on stage and provide a bass monitor to both sides of the stage. Sometimes I'll just run a line over to the keyboard players amp and let him blend me in a bit so he hears where I can better...

What type of stereo fx you want is personal preference. I do agree, a splitter with transformers will certainly be the clean way to go, but you should be ok with the stereo fx pedal.
