Earthling Designs Custom 40 – Hand‑Wired, Vibrolux‑Inspired, D‑Style Magic

I swore I’d never sell this amp, but I’ve got some investments in the pipeline and apparently none of them accept 40 watts of tone as collateral. So… reluctantly… here it is.

Hand‑wired in Sydney by Earthling Designs, based around a Vibrolux circuit with some classy D‑style switching. Excellent condition, recently serviced, and genuinely the quietest amp I own.

Features & tone shaping:

Gain control - adds compression and sweetens the feel

Pre Amp Boost - extra mids, gain, and harmonic richness

Bass / Middle / Treble

3‑way bright switch

“Cut” control - trims harsh top‑end; subtle but magic with driven tones

Tighter 40W design - stays punchy, not squishy, even with tube rectifier

Build quality and components are absolutely top‑tier - worth more than the asking price on that alone.

Prefer local pickup Albert Park/Melbourne CBD, but shipping can be arranged if needed.
