The dpFX Stereo Effects Mixer is a parallel mixer designed for stereo pedals & pedalboards and is also compatible with line level signals. It can be used as a summing box that can take up to 3 stereo signals and combine them into a single stereo output.
It features high-impedance TRS inputs (buffered with JFET op amps) that can be driven by instruments (guitar, bass etc) or line level signals as well. It makes use of low distortion, low noise op amps and each input has a volume knob that goes from mute, up to +6dB gain.
The output impedance is very low ensuring the best interconnectivity with the rest of your gear.

3-Channel Stereo Mixer

With this device you can mix two signals into a single output and still be able to use the original signals since they pass unchanges through the splitter to the respective outputs.
e.g.: You can mix the L & R channels of a stereo signal down to mono and still be able to use the original stereo signal.

Stereo Splitter & Mono Mixer with Pan Control

NEW! This is the 2nd Version of our classic ACHERON Bass Overdrive.
Make your amps "growl", spice up your bass by adding some dirt without losing your FAT low-end. From a slight tasty grind, up-to massive fat growl. 'Acheron' responds wonderfully to the dynamics of your picking.

The frequency response of the circuit (regarding WET signal only) borrows elements from the SansAmp BD combined with an Ampeg B15 Baxandall EQ.

A DRY-blend function allows you to dial in as much of your dry signal as you want. The DRY signal is not affected by the Bass/Treble controls, it stays intact and it's 100% your original dry bass signal.

dpFX ALASTOR Guitar Overdrive/Distortion (Αλάστωρ)
FET based overdrive, reaching up-to distortion levels.
Make your Les Paul sound like a Stratocaster.
ALASTOR uses 3 MOSFET-transistor stages to simulate TUBE-amp overdrive while preserving the original tone of the guitar. Its gain can vary from low, mild overdrive up-to high-gain, distortion levels.
It is very responsive to the dynamics of your pick attack and the gain is easily adjustable even through your guitar volume pot. It also features BASS and TREBLE knobs giving you a wide range of sound colors, suitable for a lot of different music genres, from classic garage rock to heavy doom and stoner and even thrash metal. The DISTORTION knob is activated separately through a toggle switch. Its high input impedance and low output impedance makes it very friendly for interconnection with other types of pedal-effects.
