Spring models the sound and character of the popular artificial reverbs found in guitar amplifiers. It also goes a step further by allowing access to physical parameter controls not readily available in a real spring tank.

By tweaking these parameters, the Spring algorithm can create faithful representations of real springs or push the physical boundaries to achieve new distinctive sounds. Pay extra attention to the Tension [TNSION] and Num Springs [NUMSPR] knobs to control the amount of "sprionginess". For good measure, we've also included a tube amp style tremolo at the reverb input.

Spring Algorithm Controls
Mix [MIX]
wet/dry between reverb and tremolo dry signal
Decay [DECAY]
decay in seconds or note-based in Tempo Mode
Tension [TNSION]
Controls spring tension
Number of Springs [NUMSPR]
number of springs in the 'tank,' mixes in 1 to 3 springs
Low Band Damping [LO-DMP]
Sets the damping frequency for the low end
High Band Damping [HI-DMP]
Sets the damping frequency for the high end
Tremolo Intensity [TRMOLO]
input tremolo intensity or depth (tremolo is pre-reverb)
Tremolo Rate [TRM-RT]
input tremolo rate in Hz or note-based in Tempo Mode
Modulation Level [MODLVL]
mixes in modulation for a nice chorusing effect
Resonance [RESNCE]
metallic resonance at the [HI-DMP] frequency
Output Level
At 0 the output level is unaffected. Increase the output level of the effect by up to 20 dB or lower by 30 dB.
Tempo is turned ON/OFF on the H9 by simultaneously pressing the Right Footswitch and the PRESETS button. With Tempo OFF, tapping can be used to adjust delay parameter values (displayed as milliseconds or Hz). With Tempo ON, tempo is in BPM.
Turn effect on or off..
The Middle Footswitch can be programmed to act on the loaded Preset as a programmable controller allowing the user to switch between the normal Preset parameter values and a programmed, alternate set of parameter values. It’s like having two Presets in one.
If Tempo is ON, the display indicates the current tempo in BPM (30 to 500 BPM) while tapping and the Tap LED will blink at the BPM rate. If Tempo is OFF, the display indicates the parameter value (milliseconds for most algorithms).
