SoundOnSound magazine have reviewed the MarkL pedals for their October edition of 2013.
This is their final thought on the 3 pedals:
These are well-made pedals, which have been voiced by musicians who know exactly what they’re aiming for. While each has a unique character, they’re all in the same league in terms of quality as, say, Fulltone’s pedals. My favourite is the Vanilla Sky: it does everything you could ask of an overdrive pedal, without trampling your tone. Considering that these are boutique, hand-built pedals, the cost is very reasonable.
