This is a fantastic overdrive. The JHS Morning Glory (hailed as one of the best overdrives) sounds boxy and dry to me compared to the Toxic Twins left side, at least with my JTM style amp set cleanish and strat, in a very dynamic setup. The pedal adds to the dynamic range incredibly. The right side is just a really nice bonus, a great mid-boost or raw rock sound.
Pairs well with any other overdrive pedal I use, Archer, OCD 1.1, Catalinbread DLS etc.
