Built around the \u003cstrong\u003eTHAT Corp. 4320\u003c\/strong\u003e, it combines high-performance Voltage Controlled Amplifiers, a true-RMS detector and high-performance op-amps for precise, transparent dynamic control without sacrificing the detail of your instrument.\u003c\/p\u003e\n\u003cp\u003eUnlike compressors designed primarily around conventional guitar signals, the Bassist Compressor comfortably handles \u003cstrong\u003eactive preamps and high instrument-level signals\u003c\/strong\u003e.
