Gearank Recommendation

The Cosmonaut V2 appeared on our recommended list for Delay Reverb Combo Pedals from June 2020 until September 2022 when it was out-ranked by the EarthQuaker Devices Dispatch Master V3 and Boss RE-202.


The Cosmonaut V2 takes a different approach to controls and reverb/delay combinations.

It features three algorithms, two of which are reverb types: Luna 2 offers a darker sounding ambient reverb while Sputnik offers a brighter sounding plate reverb, with some modulation added in. The third algorithm is called the Vostok, which is based on a tape style delay pedals from ’70s.

Interestingly, the pedal lets you utilize two algorithms simultaneously via switches on the side panel.

It also features two sets of three knobs: Fuel (mix), Anomaly (modulation) and Travel (decay), so you can have different settings for each of the two algorithms you pick.

Another interesting feature is the ability to toggle tails/hard-cut bypass, and it is also compatible with expression pedals for realtime tweaking of the modulation parameter.

The Matthews Effects Cosmonaut V2 is for those who want an easy to use reverb and delay pedal with some interesting twists.
