A buffer in the chain before the splitter might sort it.

So it's not the pedal - it's the amp?
Someone who understands the theory better than I do, like @jpfamps or @RiftAmps, may be able to confirm or correct me!
Yes. The pedal does nothing more than connect the guitar to both channels.

Saw this on the Radial Bigshot page:
Q: When using two amps, will the original guitar signal be half-strength to each amp or will each amp receive full signal from the guitar?
A: with passive devices like the BigShot ABY, the signal strength from the guitar will basically be reduced by 3dB which technically means half the power. For those that do not want the level to go down, but want more of a wall of sound... products like the Radial Bones Twin City and the Radial Tonebone Switchbone employ a buffer to retain the level so that it is maintained.
That to me suggests it is in fact the pedal?

I'll change the pedal if it's that.
That would require the signal voltage to be halved, which is even more wrong.

Ok, so it is now fixed. I turned it on last night, tried A then B then both - lo and behold, the two channels were singing together wonderfully with no drop in volume - just how I wanted it.
Was then adjusting my settings and realised that my 'always on' pedal, the Rockett Josh Smith Dual Trem, which runs in the A (Normal) channel, was off (my six year old is a git for playing with my pedals). Turned it back on and noticed that the volume drop when using both channels was back. I'm not being a halfwit here - I didn't have the volume down on the pedal, it was at 1 o'clock which gives it a great slight boost. Turned it off again - both channels working fine.
So, I moved it in the chain to immediately before the ABY switcher and BOOM, it has fixed it.
Presumable something complicated and electrical in that pedal is causing this to happen when it is after rather than before the ABY. It is beyond my comprehension entirely but there you go. Sorted.
Thanks for the advice, folks. It does work brilliantly kicking in the B (Top Boost) channel...
I was slightly wrong about part of it - if the inputs to the phase inverter are on opposite sides *and* out of phase, it will work correctly because the two effects cancel out, which is what you've now found by taking the extra phase reversal out.
Which also proves that Radial are wrong about the 3dB drop. (And anyone else about 6dB.)

I was just about to recommend a Radial Bigshot to a mate who wanted to run 2 amp separately and together. It seemed to have all the right options and was within his budget but I started to get worried that it would drop the signal with both amps on as mentioned above.
Yet again, @ICBM is the voice of wisdom and knowledge. This place is great.
*goes off to send some cash to tFB which he meant to do ages ago.....*
There are plenty of amps which reverse phase - at a guess it could be a completely even split, there's no real reason to think otherwise - and many which have more than one channel which are out of phase with each other, both traditional parallel-channels like Fender BFs with reverb, and channel-switchers. This makes combining them in multi-amp set-ups complete pot luck as to whether they will work together or not.
Pedals too, as here.
