dpFX Pedals - 2-input mixer, with volume controls & phase reverse (suitable for piezo)

"dpFX Pedals" builds handmade, hand-painted pedals and custom effects (dpeffects.com). All products are serial numbered.

This compact mixer combines two mono input signals into a single mono (TS) output. It is equipped with two inputs, a TRS (A) and a TS (B) in order to give you the option of using either two TS cables or a single TRS cable. When using the the TRS input (A), leave the TS input (B) unused.

Each input channel (A and B) has its own dedicated volume control, and input B includes a phase-inversion switch for solving phase-related issues when blending signals.

The mixer accepts both instrument-level and line-level (unbalanced) signals. Its 10MΩ input impedance makes it ideal for piezo pickups, which require very high impedance to preserve clarity and frequency response. Of course it is perfectly suitable for use with regular pickups as well.

(Note: If for some reason you require lower input impedance just let us know when you place your order)

If you need additional headroom—for example, when handling particularly hot line-level signals—the mixer can be powered with up to 24V, providing approximately 22Vpp of headroom.

The extremely high input impedance and low-impedance output ensure optimal interaction with your gear, helping your signal maintain maximum clarity, tone, and dynamics.

A few possible uses:

• Mix the signals of two instruments and route it to a single amp.
• Mix the signal of an instrument and a microphone preamp.
• Convert the output signal of a stereo guitar to mono and experiment with how the phase-inversion affects the resulting sound (e.g. useful for the 1978-Gibson ES-355).
• Convert a stereo signal to mono by mixing the L & R channels together.
