One of the best, most naturally sounding overdrive pedal plugins, I know.
Sounds very convincing, if you look for these typical "Dumble-in-a-Box" Klon Centaur tones.
Works great in front of (too clean to slightly overdriven) vintage amp simulations. A perfect companion for Tweed amps, for vintage Vox or Marshall amp, but not only, also works great in front of more modern voiced amp simulations. Even sounds very good alone or only with an additional cabinet IR.
My personal perfect combination is this pedal in front of the Nembrini MRH159, all you need for almost every kind of music.
An OCD simulation in this quality from Nembrini Audio also would be nice, I think. If possible, with different voicing options, eg. between the V 1.2, 1.3, 1.4 and 2.0 GE versions.
