The ERAS National Park Limited Edition is a limited edition version of the ERAS from Walrus Audio, an analog pedal built around high-gain distortion. RockBoard's PedalPedia describes it as "a no apologies, high-gain distortion that's ready to chug, shred, and palm mute with tight response and multiple clipping options"1. Beyond distortion, the pedal is also listed as an equalizer, booster and overdrive, so it can cover several dirt and tone-shaping roles on a board1.
What it does
At its core, ERAS delivers tight, high-gain distortion aimed at chugging, shredding and palm-muted playing, with multiple clipping options to shape the gain character1. The Blend knob is the pedal's main tool for fitting it into a rig: at maximum it gives the full distortion sound, while rolling it back lets you stack and mix other dirt pedals in front of it, or blend in dry signal, which Walrus points to as useful for bassists1.
For players comparing it within Walrus's range, the standard ERAS Five-State Distortion shares the same core design, and the maker's heavier-gain side also includes the Iron Horse and Red High-Gain Distortion. More broadly, see the site's guide to Distortion Pedals.
Power
The pedal runs on 9V DC, center negative, and draws 100mA1. That current draw means a low-output daisy-chain supply may not be enough; a dedicated 9V output rated at 100mA or more is the safe choice.
As a limited edition, this version's availability is tied to its production run; the standard ERAS remains the non-limited alternative.
Walrus's manual for the ERAS (English) is available as a PDF from the maker1.
