Seward Park Electric has released the Maravilla, a hand-built germanium preamp and overdrive pedal, Guitar Pedal X reported on July 24, 2026. The pedal is listed at $180 on the Seward Park Electric Webstore¹.

The circuit is analog and runs on 9V DC, center negative². Premier Guitar reports it is powered by an external supply with no battery compartment and features true bypass switching³. Seward Park Electric says each unit is designed and hand-built in Seattle, Washington³.

The controls are Loud (master output), Tone, Mid, Air (presence), Pre Gain and Post Gain¹. Pre and Post are independent gain controls into each of the two germanium stages, and Post can be adjusted to saturate the onboard audio transformer¹. Premier Guitar describes the transformer as adding natural compression and dynamic responsiveness, pushing into saturation reminiscent of a vintage amp when driven hard³. Air is a presence-style control that adds openness and definition¹.

The two outlets differ on the transistors. PedalPedia's listing describes a Russian NOS germanium transistor². Guitar Pedal X notes that the description cites vintage germanium transistors but does not name the exact variants¹. Premier Guitar refers to vintage germanium transistor technology without naming parts³.

Seward Park Electric's description of the pedal:

Guitar Pedal X's Stefan Karlsson wrote that the pedal takes players "into fuzzy-drive territory" and called it "Really cool pedal though!"¹.
