Preamp booster designed to provide an additional channel of gain for your overdrive pedals or to brighten up your bass pickups. It boosts the mids, tightens the lows and makes the highs shine while pushing your saturation to achieve more sustain with excellent harmonics. Use it to remove the clutter from big bass fuzz pedals, to push light overdrives to higher gains, or to simply boost your sound. The new v2 version has a new housing with top-mounted jacks and a quiet relay switch system.
