This is a great pedal, very well built, very tweakable - I'm just taking one star off because switching presets requires to cycle through them with a small button that isn't easy to action by foot, but it wouldn't have been easy to do better.
It takes a little while to adjust and remember what some knobs do on some effects, but the cheatsheet is very well done, and it's just a matter of experimenting a bit to find the right settings.
The wiring options with the pre in / out and post in / out are really cool. I use it with other drives & a HX stomp, and this allows me to do Guitar -> Terraform pre -> drives -> HX stomp in -> HX stomp send -> Terraform post -> HX Stomp return. I place the FX loop of the stomp in the relevant block, and then I can choose if effects are applied before or after the gain stages. Really cool.
I haven't explored the use of external midi controls & expression pedals, but it's available for those who want to use this.
Special mentions to the uni-vibe, rotary, tremolo, harmonic tremolo and dimensions chorus. Not so keen on flanger & phaser effects, but maybe I just haven't found the right settings for these effects.
A great pedal, which isn't cheap, but it provides really good tone and value for the money !
