Churning with sound, this tremolo/vibe pedal was made for the innovative player who wants to create a unique atmosphere with their playing. The SwirlPool Jr features awesome sonic potential, easily adjustable controls, and a solid build that will last.

Awesome Sonic Potential
Built with the world-renowned vibrato and tremolo sounds of vintage 60's amplifiers in mind, the SwirlPool Jr is a fully-analog brute. The pedal features both tremolo and vibrato tones, which can be used individually, or blended together, affording a wide pallet of effects. You can fine tune the vibrato sound with the mini switches. The Tone switch can afford a "surf" sound with long, wavy vibes, while Sync adjusts the character of the blended and synchronized tones.

Easily Adjustable Controls
With all the options for shaping your sound, you might think the controls would be a bit overwhelming, but not so. The Amptweaker SwirlPool Jr sports the classic metallic on/off footswitch to engage the pedals effects, or go into true bypass mode. Holding the switch down engages a second speed, which can be user-adjusted via internal trimpot. The three black knobs allow you to seamlessly blend the amount of tremolo, vibrato, and speed 1. Changing the nature of the vibrato is easy with the toggle switch to the right, and the type of tremolo can also be adjusted with the toggle switch to the left. All-in-all, the SwirlPool Jr has comprehensive and intuitive design.

Solid Build
The SwirlPool Jr is a powerful effects pedal derived from Amptweaker's popular (and larger) SwirlPool.  This pedal is a bit more compact so it can fit on any pedalboard. It boasts a pedalboard-friendly design and weighs only 9 ounces. Nonetheless, this baby is still built strong to last long. It's even got a thumbscrew removal bottom with holes for tie-wrap or screw-in attachment.
