Modulation effects from MxR are generally good, phasing in particular. 100% analog pedal, directly derived from the model originally released in 1977, no need for an app or smartphone to use it.... Luckily, it remains timeless and will still be a reference in 20 years when digital pedals full of gadgets become obsolete.
