Screams like a Children of Bodom track

Installed this in my ESP LTD and the difference is night and day. The gain structure is tight and perfect for metal.

Perfect mid-range punch

Exactly what I was looking for to cut through the mix. The active boost doesn't add noise which is a huge plus.

Great circuit, needs space

Sounds fantastic but make sure your guitar cavity is large enough. Had to route some wood to fit the battery clip.

Best upgrade for the price

Feels like I bought a new guitar. The sustain is improved and the highs are crisp without being harsh.

Recording ready tone

Tracks beautifully. No hum or buzz even with high gain settings. Highly recommend for studio work.
