The EQ01 is the newest preamp offering from the team of ACG and John East. It is also filter based like the EQ02, but with a feature that will be instantly recognizable to players or fans of Alembic or Wal basses.
It has dual lowpass filters, one for each pickup independently. The dual lowpass setup has long been recognized as one of the most versatile tone shaping configurations. The idea being that it is possible, via the resonant peak of the lowpass, to 'retune' the resonant frequency of each pickup individually before the summing of the two signals. In this way you can emulate the frequency response of any bass or pickups in existence.
While some may say the circuits ability to perform this trick is debatable... as comparisons of such an 'emulation' against 'real' versions of various basses will no doubt reveal some subtle details being still different. There is no doubt that this is one of the most powerful tone-shaping packages ever offered to the public at a reasonable price.
The EQ01 pre-amp comes in a 4 stacked knob configuration. Volume/blend stack. Lowpass filter stack for the neck pickup connected with flexi to main board.
