I currenty use three different overdrives from time to time. A Soul Food, a Tube Screamer mini and this one. I would say that this one is my favorite among them when used standalone.
The overdrive works well as an overdrive that colours the sound beautifully. When using it with a Stratocaster you can play for hours. The pedal can also produce quite some distortion.
The knobs control gain, volume, low- and high frequencies. A knob for mids would have been appreciated, but it's not that common on pedals, so it's not missed.
I'm happy I bought the pedal and I can highly recommend it.
