Frequently Asked Questions

What kind of instruments can I connect to the True Spring's inputs?
The True Spring's audio inputs are high impedance (~ 1 MΩ). It can accept high impedance signal
sources like guitars/basses with passive pickups, as well as low impedance sources like line-level
audio circuits, guitars/basses with active pickups, electronic keyboards, or mixer outputs. The input
circuit can handle signals ranging up to 5.6 Volts, peak-to-peak.
Can I power the True Spring directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the True Spring needs 9 Volts, so the pedal cannot be powered directly
from USB. Make sure that you have plugged in the included 9V DC power supply when connecting to
the True Spring's USB port.
When connecting the True Spring to a recording interface or mixer, should I used a Lo-Z
(microphone) or Hi-Z (line / instrument) input?
The True Spring's output will be low impedance when the effect is active or in buffered bypass mode,
but it will be high impedance when using true bypass mode and a guitar with passive pickups.
Therefore, it is recommended that you use a high impedance (Hi-Z) input on your recording interface
or mixer to avoid signal loss.
How do I enable Spring Reverb engines via MIDI?
Refer to the Custom MIDI CC Mapping section to map a MIDI continuous controller to the Spring
Reverb engine. Then, send a CC message with one of the following values to enable a certain effect
type:
CC Value Effect Type
0 Short Spring
1 Long Spring
2 Tank Spring
3 Tiny Tank
4 Triple Spring
5 Space Spring
6 Drip Machine
7 Hall S
8 Trash Can Spring
9 Ventris True Spring
