Amentum Boost

Compared to the EQD Arrows, a compact, always-on-friendly preamp boost from Earthquaker Devices, this build captures its hallmark clean headroom and subtle harmonic push. The Arrows built a following as a near-invisible signal enhancer — equally at home before a vintage amp or stacked into a drive pedal — and PedalPCB's layout brings that tonal utility to the DIY bench.
