Simulate Vintage Echoplex Units With the Bias Control

The Epoch Bias lets you replicate the Echoplex experience of yesteryear. Old EP-3 units had a wide range of tonal variance. The Bias control gives you that same flexibility, adjusting gain and body as if you were tweaking vintage gear. Adding just a touch of grit, it brings out the best in your tone. For many guitarists, this alone is all they need. The Bias control interacts with your pickups and amp to add the perfect amount of punch and chime. Dial it in to complement your core sound, whether you want more beef or sparkle. It's like having an endless supply of prized vintage Echoplex units.

Tame Brightness With the Filter Control

Some amps and pickups lean on the bright side, but the Epoch Bias can tame that harsh treble. The Filter control is based on early and late Echoplex models, which had differing high-end responses. Turn it clockwise for a dark, rolled-off top end. Counter-clockwise yields more shimmer up top. With the Filter knob, you can remove ice pick highs and adapt the Epoch Bias to any guitar and amp combination. Between the Filter and Bias controls, you have the tools to sculpt an idealized EP-3 sound. The Epoch Bias works with your gear, not against it.

Experience the Preamp That Defined Rock Guitar Tone

Plug into the Epoch Bias and understand why the Echoplex preamp is so coveted. Its touch of pleasing grit and compression brings out the best in any guitar and amp. Dial in the perfect amount of grind to enhance your tone. Shape highs and lows to complement your existing rig. The Epoch Bias makes it easy to get those iconic rock tones, allowing endless fine-tuning.
