DSM & Humboldt Dumblifier Overdrive Special – Mint Condition – Serial #1225-0444

Up for sale is a DSM & Humboldt Simplifier Dumblifier Overdrive Special in essentially mint condition. This unit was purchased new when first released and used only a couple of times on a studio desk — it has never been mounted on a pedalboard or placed on the floor.

This is an exceptional fully analog preamplifier, one of a kind, capable of replicating the sound of a tube amplifier with extraordinary accuracy— this is a rare opportunity to get one in mint condition with original box.

The Dumblifier is DSM Humboldt's flagship zero-watt amplifier and preamp, combining the legendary Dumble-inspired overdrive circuit with a full stereo cabinet simulator and studio-ready DI outputs. It is the ultimate amp-in-a-box solution for recording and silent stage use.
