I reckon you might enjoy the current Dimehead NAM Player - it probably takes the same space up on a board as your 3 x tonex pedals.
I might enjoy it - but I'm not using 3 TXOs on one board, just one (ok, there's two on the big board as I haven't yet decided to order a second Pirate MIDI Pico controller). And it's really all I need with patch switching available.
This is the current small board:
It's incredibly capable for such a small board, really (the awkward basic programming of the GT-1000 aside). And there's absolutely no space for a thing such as the Dimehead (and I wouldn't need anything but one single NAM capture at any time anyway, so all the controls, the screen and what not would go wasted). Let alone it doesn't have the TXO's autosave function (which is really really handy for the way I deal with things).
Seriously, if they came up with a single pedal sized unit with a clever encoder layout for, say, €200-250 (which I think could get them a decent profit margin), I'd instantly buy it. I prefer the NAM ecosystem more than what IK offers with Tonex, especially with the TXO, which requires an extra box for MIDI support, has super tiny pots that aren't endless, etc.
For my needs, it could offer *zero* fuss. Just let me load a NAM capture and EQ it - maybe with two EQs, one pre, one post, then allow me to route whatever EQ controls to 3 BMT encoders (plus global gain and level controls) and I'd be the happiest camper.
Wouldn't need a headphone out, FX or whatsoever, either. Just mono I/O, TRS MIDI, USB C and 9V. OK, maybe BT would be cool to manage the thing wirelessly from your mobile device(s).
I'm sure quite some folks would like such a thing - I mean, you could use it with, say, a Stomp, a VP4, an HX FX, any other small form factor MFX unit, along with your pedalboard (even more so in case you're using MIDI already), etc.
