GuitarPCB releases NostalgiTone MAGNETAR gain circuit PCB
October 1, 2026 · 1 sources
GuitarPCB has listed the NostalgiTone MAGNETAR, a printed circuit board for a Sunn-inspired gain circuit, dated October 2026 on the maker's product page. The board is listed as in stock.
The maker describes the circuit as having a full-range response that retains its weight and character in both standard and drop tunings. Its BURST and IMPACT controls shape what the maker calls its raw, amp-driven saturation, and two J201 gain stages with internal bias trims give the circuit its voice. The maker says the design focuses on driving those gain stages and exploring the intensity, texture and character of the resulting breakup.
The maker states that the MAGNETAR works as a standalone gain circuit and also when stacked with other overdrive and distortion pedals, either pushing an already driven signal into more saturation or adding density to a cleaner sound.
"MAGNETAR stands on its own as a powerful gain circuit, but it also excels when stacked with other overdrive and distortion pedals."
