The best analog reverb pedal with real spring tank… Here’s why:

Real spring reverb tank. Mind Blowing Tone. Nothing Like It Out There. My goal was to design a real spring reverb pedal that would be the best sounding available and offer new tonal possibilities. Nothing digital, no modeling anything. Just solid analog design and a real spring tank. Try whacking it! You’ll hear the springs ring just like they should. It works across all musical genres, from surf to blues to modern rock to dark and soulful jazz. This pedal has something for everyone and probably more reverb than anyone needs.

Euphoric sounds

This guitar pedal does reverb, but it also makes some unheard of sounds because I enabled a completely Wet sound that goes through the ThunderTube driver circuit. What is the ThunderTube? ThunderTube is a JFET circuit which acts a heck of a lot like a real tube amplifier. Soft, supple yet ready to crank and give you a warm glowing distortion if you turn it up.

Details of how it works

The Uverbia is a real spring reverb pedal which has a driver that sends a signal to a spring tank in a similar manner to a guitar amplifier. The mind blowing tone comes from the fact that this pedal has a real spring tank, not a digital modeling unit that is commonly found in many pedals. Your signal goes through the set of real springs and reverberates back and forth. The Wet and original Dry signal is mixed and then run through a warm amplifier section with controllable gain profiling. This results in an unbelievable array of reverb sounds that you can’t get with a digital chip.

Huge range of reverb tones

The Uverbia has a control for Dry / Wet and a control knob for the amount of Reverb sent through the tank. The Dwell of the springs can also be controlled which is basically the delay time and profile of the reverberation.

ThunderTubeTM

I designed the ThunderTubeTM solid state output driver which acts in a similar manner to a tube amplifier, when it’s low you get a nice warm clean sound that makes you want to play a blues lick or two, when it is cranked, you get a subtle and warm distortion that enhances the harmonics and gives you new tones to play with. It can be used to enhance the sound of the reverb or to interact and drive your actual stage amplifier (like a tamed down TubeScreamer). This section controls the volume and gain of the Uverbia which works in conjunction with the Snap switch described below.

Wet / Dry: This knob controls the blend of Dry (no reverb) and Wet (Reverberated signal through the tank). Fully on, almost no signal goes through the Dry section of the Uverbia.
Dwell: This knob controls the delay time and sound profile of the reverberated guitar signal through the tank section.
Volume: This knob controls the volume of the Uverbia.
Gain: This knob can be used to maintain stage volume (more gain from just the Volume knob) and also kick up the overdrive of the unit. When cranked, you can hear a warm distortion that pushes a tube amplifier into happiness.
Snap: This switch controls the gain profile of the ThunderTube section. One side has more treble, one side more gain across all frequencies and the middle is the flattest response. If Gain is cranked, this switch does not change the sound much.
