I got to hand it to IK though, they really hit it out of the park with the Tonex One by being able to deliver it cheap yet keep the tones at a level the Asian competitors are not reaching atm with their NAM conversion products.
Add to this that the TXO with a capture loaded comes with an RTL of around 1.5ms (seems to depend a bit on the capture), allowing it to be combined with pretty much any other half decent digital unit without crossing any latency threshold lines that quickly. Can't be said for all those Asian boxes. The Valeton GP-5 (possibly the best out of the smaller ones) kicks in with something over 5ms already. Run 2 devices serially and you're at 10ms, which is quite not so great under headphones anymore. Run 4 TXOs in series and you're at 6ms. Or, like me, a GT-1000 with two serial digital loops plus the Tonex, still ending up with an RTL number of pretty much exactly 3ms. You get the idea.
The Tonex is good to enhance pretty much any rig and the amount of pretty great captures even available for free is amazing. Sure, not NAM-level amazing - but it's a whole lot easier to sort them out - and the option to do that sorting out in the plugin and then transfer your patches to the hardware is absolutely fantastic (in some aspects it's even quicker than with the L6 HX ecosystem - sure, it's more limited but plugin and editor presets including IRs being kinda synced automatically is gorgeous).
As an example: I'm planning to build a second small rig just using a TXO and an HX Stomp (and possibly some additional small form factor MIDI foot controller for a semi-advanced version of that). Overall latency with the TXO in the Stomp's loop would still be less than 4.5ms. Add some of these Builty devices (PM Pico or built from whomever) and a small MIDI controller for a somewhat larger (or rather extended per situation) and you'd have an almost insanely competent setup (or get a Stomp XL).
The HX Stomp can be found used for around €450, a TXO is around €160, the Pico-kinda device might set you short another €100, same for, say, a Hotone Ampero Control (wired MIDI is a better choice for controlling both the Stomp and the TXO) for another €100, a decent PSU for another €100 and a DIY pedalboard for next to nothing (or go for a HB Spaceship Power 40, which would leave some room for EXP pedals and what not, PSU included) and your overall cost would stil be just around €900.
If you'd deal with it as I would, you'd only switch patches on the TXO and keep the Stomp at one preset per gig and only switch things on/off there. This would give you instant switching (there's literally no gap in the TXO's switching) and reverb/delay spillover.
I just created a prospective live patch, the Stomp running one drive, one EQ, two modulations, two delays and one reverb. That's all I'd ever need for pretty much any single gig (I might exchange one or the other blocks depending on the gig). Might add a wah and an EXP to taste.
Ah well, that would actually belong in the Tonex thread, but it goes to show what the TXO can do in combination with other devices.
