Hi everyone, first thanks for always clearing these things up for me when I post something.
What I'm wanting to do is split my guitar/bass signal to two different DI setups I have going that both get sent to two separate amp sims. Basically I'm doing the "playing through two amps simultaneously" thing except the amps are in my daw. Sure, I can just use one of the DI setups, send guitar to amp sim through it and then, once in the daw, split the guitar signal to a second separate, isolated amp sim using auxes, which I also do. But the reason I want to split to two DIs is that one of my two DI rigs is a Sansamp PSA-1 which has an amazing sound of its own and I'd like to blend that sound w/ an amp sim in parallel on input, essentially playing through two separate amps simultaneously, but digitally.
There's aby boxes at all different price points and I've read plenty about how they can suck tone especially if you have to flip the polar switch if it even has one. Phase shouldn't be a problem though in my case because my amps/speakers are digital; no physical speaker interaction to deal with, but ground lifts are still helpful.
Here are my two DI rigs and their respective signal flows:
DI 1: Golden Age Pre-73 which has a DI function and I plug into its "Instrument" input to utilize it. The GAP output goes directly to the interface/sim.
DI 2: Sansamp Psa-1, line output goes directly to interface where it then reaches Recabinet IR loader using Ownhammer IRs, which has worked out famously as the PSA-1 has no speaker sim of its own and benefits greatly w/ some.
I want to play both of those DI rigs as if they were two separate amps w/o any gain loss or high end roll off on either rig and I don't want to spend more than $200 to make it happen.
So for now it came down to two aby boxes: the Radial Twin City and the Lehle P Split II. The Radial has buffers etc and Radial claims that this box will not alter your tone at all - and sorry, but it *absolutely does alter the tone* in my case, where Output A to the Golden Age adds a bit of gain, which was actually ok, but Output B on the Twin City to the PSA-1 suffered gain loss and high end roll off. Wtf. This is confusing as I thought the buffers on the Twin City were supposed to retain signal integrity. Anyone know what's happening here?
At this point I'm feeling like combining these two DI rigs the way I've described is a pipe dream. I've read that you're going to suffer some change in signal no matter what when you split and that it comes down to what changes to the tone you can/can't live with. I can't live w/ tone loss on either side. If the Twin City had just boosted the gain a bit ON BOTH outputs I could have worked w/ that but I'll have to send it back.
Idk if this post is so much a question or a lament. Well is anyone else out there trying to do what I've described here? Any tips? Should I even bother trying the Lehle P-Split II or will that suck tone too? Is there another box anyone recommends? Ok thank you
