Infinite Low-end Essentials in One Immaculate Pedal When it comes to bass rig essentials, vital gear can quickly turn into a mess of cables and stompboxes.

What resulted is the Darkglass Microtubes Infinity, an all-in-one stompbox that’s a versatile preamp/DI, a multi-voiced distortion pedal, a compressor, a tuner, a USB interface, a silent practice rig, and more! With three footswitches, six touch EQ sliders, preset options, and formidable I/O, the Darkglass Microtubes Infinity offers endless tonal possibilities, all rendered in immaculate Darkglass hi-fi that Sweetwater bassists have grown to love.
