T-Rex Quint Machine

Firstly the quality is great, every part feels great, no extra noises and no noticeable signal degradation.
Now the drawbacks:
-There is definitely latency. Maybe it's lower than in most of the other options, but it's there.
-It sounds somewhat 8-bit Nintendo-ish, this could be fun sometimes, but you need to dial it quite back for a more rock-oriented sound.
-The Mix knob complicates things for no reason, it messes the octave balance with both the dry signal and the master output, so for unity gain you might have to dial the Mix in a spot that doesn't sound best.
It would be much easier, simpler and better sounding if there was a Dry Volume knob instead of the Dry-/MasterWet Mix knob.

Also keep in mind that it's not polyphonic, it can track certain arpeggios but it can't handle chords.

All in all I wouldn't change it for a POG, but I'l keep searching for a better tracking, faster and more natural octave pedal.
