FX63 Deep Freeze

Both cosmetic variants of the FX63 Deep Freeze, from 1996 (left) and 1997

The FX63 Deep Freeze was based on the FX64 Ice Box's circuit, but voiced for bass guitar and with a blend control. Like the FX64, the FX63 is an analog chorus, using a MN3007 BBD chip. Two cosmetic variants were made, with the second version featuring the "real" control names above the knobs. The FX63 Deep Freeze debuted at Summer NAMM 1996, replacing the FX62 Bass Stereo Chorus, and remained in production until 1998.

• Controls: Chill (blend), Cold (speed), Deep (depth), Defrost (high e.q.)
  
  
• From the manual: "The FX63 Deep Freeze is a specially designed bass chorus with crystal clear high end. The Deep Freeze has been fine-tuned for bass guitar to add dimension and width to your sound. Extra time has been taken to create the correct type of LFO that sounds great at all speeds. So change your bass sound from blah and "clinky" and give it breath-taking, crystal clear images."
