Hybrid tube + digital rig with Quad Cortex — legit setup? Captures vs models

Quad Cortex
1

Hey everyone,

I’ve been using my Neural DSP Quad Cortex for about a year now, in a bit of an unusual way, and I’m curious what you think.

I basically run two different setups:

Option 1:
I only use the effects on the QC (overdrive, delay, chorus, etc.) and go straight into my Victory V40 The Duchess.

Option 2:
4 cable method — everything the same, but in this case I use the QC amp models instead of the V40’s preamp.

Main question:
Is this considered a legit approach? Am I essentially running a hybrid tube/digital rig?

Second question (captures vs models):
Sometimes it feels like the QC amps sound better when they’re captures, but other times the modeled amps sound just as good.

Technically, what’s the real difference between the two?
I understand captures are based on real amps, while models are algorithm-based — but can both reach the same level of quality, or is it generally better to stick with captures?

Tuner question:
Is there a way to set up the tuner so it activates with a single tap of the right footswitch, or is double-tap required?

Final question:
Is anyone else running a similar hybrid setup (tube amp + QC)? Would love to hear your experiences or any tips.

Thanks!

  1. yes, many are running this Hybrid setup.
  2. Technically, all NDSP amps are based on capture technology. Even the models are basically containers for multiple captures which they’ve used their neural network to ‘fill in’ the gaps between settings. They don’t model based on components. So, theoretically neither is ‘better’ or more accurate, it just comes down to your taste and what feels/sounds best to you.
  3. The MIDI Jumper hack is really the only option for a 1-press Tuner solution. You can then use an XP or external switch or onboard footswitch, but it relies on the Midi hack (connecting the QC to itself with a midi cable). Otherwise, you have 2 onboard options as we described here: Quick Access to Tuner with One Pedal Click?
