The EBS ValveDrive DI. Real tube tone—from smooth warmth to raw grit.

The ValveDrive DI is a tube preamp and overdrive pedal that gives your bass true analog warmth or screaming tube distortion, all in a simple, versatile design.

Classic Tube Character

Use it as a preamp: Set Gain low, crank Volume, and transform any solid-state rig into a warm, punchy tube amp with natural compression.

Push the Gain further for rich overdrive or full-on tube distortion.

Toggle Vintage or Normal modes to fine-tune your drive flavor.

Unique EQ setup: Bass & Treble at zero + Mid max gives a flat response.

Pro-Ready Connectivity

Balanced XLR out lets you go straight to the board—ideal for both studio and live setups.

The upgraded low-impedance output replaces the old passive one, so you can now drive a power amp directly and use it as a full-on tube preamp.

Built for Tone & Flexibility

High-quality ECC83 (12AX7) tube delivers authentic tube feel—swap to an ECC81 for lower gain.

Now runs on standard 9V DC power (supply included), instead of 12V AC, for easier integration on any pedalboard.

The ValveDrive DI delivers what many tube pedals promise but few achieve: real, warm, full-bodied tube tone—no compromise.
