I was at Davis yesterday & managed to try this overdrive by Mojo Hand effects- Rook Overdrive.
A positive take here is the fact that it's not a Tubescreamer wannabe; it's just there to churn out overdrive according to the manufacturer's interpretation. The GAIN control does some effective shaping of drive intensity. The mini toggle provides 3 drive voicings to suit your needs. I am a high gain/drive fan but I enjoyed the Rook Hand in its reduced gain setting (Toggle position 1), it has that great note clarity despite running on lower intensity. It makes a good booster in this mode. If you need some top-side poke, Toggle position 2 has lots of that in store. The middle position is diode-free for a cleaner boost to your tone.
The Rook OD is recommended for those of us in search of overdrive goodness per se, not a Tubescreamer clone or something along that line. Personally, I hear great lead tones coming from it in addition to some serious thickness on board, it's a matter of tweaking. Would they have one with a midrange control in time to come (for me)? Hmmm.. :-)
