The ToneX One isn't flawless, but it delivers so much, for such a reasonable price. I can't recommend it enough!
First, it's just so many things for 170€:
- If you plug it into your computer, it is a surprisingly good audio interface, although you should turn off Direct Monitor.
- If you plug it into a wall, it is a fantastic practice amp.
- If you put it on your pedalboard, it is a good enough 'Pedal X', that can be an Ibanez Tubescreamer, or ProCo RAT, or Klon Centaur, or whatever you choose it to be.
- It is also a basic tuner, if you don't already have one.
The best feature is that once you have your presets dialed in, you can take the ToneX One with you anywhere, and always get your sound right. You only need a computer to help with the initial configuration, but once you're set, you can use it as a regular preamp or pedal. It supports USB bus power, so you don't even need to carry a 9V power supply.
This is one of the products where reading the manual is a must. There are a lot of features packed into this tiny device and each knob has at least 3 different functions, depending on the mode. You can operate a lot of the ToneX One functionality without a computer, and it can stores 20 different presets, which are really easy to access from the preset browsing mode, enabled by pressing the Alt button and footswitch at the same time.
Some people find the software (Amplitube, ToneX, ToneX Editor) awkward to use. You can get used to the weird UI/UX quirks, but there is definitely a learning curve. You do get new features and expanded functionality, delivered with free patches. Worth mentioning that the ToneX One, unlike the ToneX Pedal, comes with the barebones version of Amplitube and ToneX software. This said, most of the good presets are the ones users upload on ToneNet, so don't feel like you need to upgrade.
I think the Tonex One is the absolute best product IK Multimedia currently produces. The value proposition is fantastic, and it significantly lowers the barrier of entry into the wonderful world of electric guitars and basses. Of course, it is not for everyone, but if you have written 10,000 word essays on how Leo Fender 'got it right the first time' with the Fender Precision, and how Ampeg is the only amplifier anyone really needs, you're not the target audience anyway.
