- Greater Note Clarity - Individual notes within chords are heard with greater detail. Higher frequency signals such as harmonics are especially clearer as they tend to be the most affected by circuit loading.
- Improved Transient Attack - the instrument sound becomes more responsive to the player's picking velocity and strength.
- Greater Linearity and Transparency - The timbre of the instrument stays consistent, especially when “rolling back” the volume controls. This reduces any loss of high frequencies when you turn down your instruments volume.
- Feed Directly Into Mixer Line Input - Because the output impedance is less than 300 ohms, the circuit can easily drive the line input of a mixer. This results in a clear, full range of tone that sounds better than using a direct box for live or recording applications.
Here are Creation Audio Lab's specifications for the Redeemer Circuit: Flat frequency response: 10 Hz - 50 kHz! Noise floor: -125 dB! Distortion: 0.0005% Input Impedance: > 2M ohms Output Impedance: < 300 ohms Current Draw: < 2.5mA Power: operates from 9v to 18v Phase response: between +/- 0.1 degree from 20 Hz to 20 kHz Dimensions: 0.4" x 0.8" x 1" (metric = 1.0 cm x 2.0 cm x 2.5 cm) and a 9 volt battery Take a look at this video to hear an A/B comparison of the Redeemer Circuit in use:
While the most common application of the Redeemer Circuit is to install it inside a guitar, the following video illustrates an application where it is placed inside a volume pedal, so that one circuit can be used by any instrument.
At the time of writing the Redeemer Circuit was available from Creation Audio Labs and other sources for $49.
