i am bassmaker, and so can you
Bassmaker started out of isolation. I was on assignment in China, helping build one of the last rides for Shanghai Disneyland, and what a ride it was. The catch was that I lived in the factory. If you've ever spent a night in a Chinese factory, you know sleep is limited, if not banned outright.
So, like any man doing time, I took up whatever hobbies fit inside the walls. First it was Mandarin lessons, promptly followed by chainsmoking. Then, as a cure for my incessant boredom, a pair of speakers pulled from a scrapyard went into a briefcase that had survived the Cultural Revolution. The first Bassmaker was born.
Living in Guangdong, the factory of the world, meant the people who build the electronics we all use weren't suppliers I had to cold-email. They were my roommates. So I played dumb, asked a lot of questions, and paid my way in loose cigarettes and 白酒.
Friends wanted one. Then friends of friends. That briefcase became a company with three rules: loud enough to matter, tough enough to travel, honest about what's inside. No inflated wattage, no fantasy specs on the box.
Then people started asking if they could put their own logo on it: agencies, festivals, breweries, artists. This is when it became a marketing vehicle.
For four years we pumped these bad boys out, but we also learned from the feedback. New tech made it possible to reduce the size and weight while increasing the power, among other net benefits for v2. Which we childishly dubbed the Treblemaker.
Most branded merch is designed to be thrown away. A Treblemaker is the thing someone carries to the beach five summers running, with your branding on it every time.
We're small, so you talk to the person who actually builds these. If something's wrong, I want to hear it from you directly. Send me your artwork and I'll show you what it looks like on the real thing.
— stew
brands that already did it




















take a peek at our past work. and fyi — we're liquidating old stock while it lasts.
shop the liquidation →not on this page. the treblemaker is a wholesale build, made in runs for brands. single units live over at bassmakerstereo.com. a direct-to-consumer treblemaker is on the table; join the list and you'll hear first.
50 units per run. that's the point where custom tooling, print setup and sea freight stop being silly and start being cheap per case. above that, price drops with every tier.
no. it's a parody of a briefcase, not a briefcase. if you need an actual briefcase, contact us — we have a guy.
vector, preferably — ai, eps or pdf. if all you have is a jpg of a logo from 2011, send it anyway and we'll help convert it. we lay it out and send a proof before anything gets printed.
sea freight to one primary delivery address, yes. air freight, split shipments, or individual drop-shipping to recipients cost extra — ask and we'll price it.
any instrument you like. the 1/4" channel plays alongside bluetooth with its own volume control. yes, karaoke. yes, an activation host with a mic.
completely. white-label is standard — every bit of bassmaker branding comes off, and the unit ships as yours. uv printing for the main run, heat transfer vinyl for anything added downstream.
one year limited, every unit in the run.
didn't see your question? ask away...
email your question →not buying a run? a single-unit treblemaker is coming to retail. no date yet — leave your email and you'll know before anyone else does.
done. you'll know first.
one email, when there's actually news. meanwhile the original is still for sale at bassmakerstereo.com.
