Main Logic Board Assembly
The main logic board contains the integrated Bluetooth SoC and the Digital Signal Processor (DSP). Audio lag occurs when the SoC fails to properly synchronize the A2DP audio packets with the local guitar signal, often due to a failure in the internal crystal oscillator or memory buffer underruns. Replacing the board provides a new chipset with a factory-calibrated Bluetooth stack and synchronized timing protocols.
