JF-38 Roll Boost

The JF-38 Roll Boost provides clean gain increase without coloring your tone. This transparent boost pushes your signal harder into downstream pedals or your amplifier's input, creating natural overdrive from tubes or saturating dirt pedals further. The adjustable gain control sets the amount of boost from subtle lift to significant push. Use it at lower settings for solo volume bumps or crank it to drive your amp into natural breakup. The circuit maintains your guitar's frequency response without adding coloration. True bypass switching removes the boost completely when not engaged.
