The PAC ATTACK is an audio bypass board based on the Triple Bypass V2 by Tian Feng and alters the audio response of the PAC-S10 cartridge audio to more closely match a Genesis/Mega Drive Model 1 VA3.

MDFourier Comparison
Presented here is the MDFourier analysis on a stock PAC-S1, which has the service bulletin audio fix already integrated into the design by Pioneer. While the PSG and Noise channels are well aligned with a Model 1 VA3 Genesis, the FM audio has a sharp cutoff. Installing the PAC ATTACK moves the cutoff frequency for FM audio further out, making the frequency response more even across the range.
