Questions
What does the Plus Boost footswitch do on the NRG Effects Purrer?
The Plus Boost is a second stage built into the Purrer, switched by its own footswitch. Guitar Pedal X describes it as elevating Gain, Volume and EQ or Character, so you can set a base overdrive tone and kick into a fuller, louder version of it for solos or bigger passages without a separate pedal on the board.
How much does the NRG Effects Purrer cost?
Guitar Pedal X's 2024 buying guide lists the Purrer Organic Overdrive with Plus Boost at £299 / $379, as stated in the guide. The same site's October 2024 review of the Purrer range priced the 4-knob edition at £259 and the 5-knob Plus edition at £299.
What does the Purrer sound like compared to other overdrives?
Guitar Pedal X's Stefan Karlsson places it very roughly in BluesBreaker territory, meaning a warm, even-tempered overdrive in that family, but says it is far more expansive and very much its own thing. He calls it a beautifully engineered organic overdrive.
