MaxxPlay UB2 Booster




The UB2 Booster is not a distortion box of any kind but, a discrete JFET preamp, designed from some of the greatest boosters of all time.

We have built many of these for players in our area, and seems they are always received with great comments. Players like the organic, uncluttered, natural tone.

A very basic, direct, hand wired, point-to-point circuit with only two knobs:

  • Input Level
  • Output Level

The tone of this circuit is not cold or sterile at all, it is the sound of your guitar and your amp. It plays nice with other pedals and reacts well to the guitars volume control.
