Ashdown LoMenzo Hyperdrive

Bass distortion

The LoMenzo Hyper Drive is a bass specific distortion unit
providing a unique range of distortion effects as envisioned by
James LoMenzo, bassist for Megadeth. The operation of this
distortion pedal is totally unique and unlike any previous and
existing distortion or overdrive effects units. A band of frequencies
within the Mid range of the bass signal is filtered out and the
distortion effect is added only to this band of frequencies. The
filtered frequencies can be ‘tuned’ to the precise range that gives
the optimum effect. The degree of distortion available is variable
from a slight effect only to well over the top, allowing for a new
range of extreme effects for bass to be produced. The resultant
distortion effect can be mixed in with the original ‘Dry’ bass signal
maintaining a full bodied powerful bass character with distortion
overtones.

FREQ CONTROL & ‘Q’ SWITCHThe FREQ control adjusts the band of mid frequencies that are to
be subjected to the distortion effect. The range can be swept from
200Hz to 2.2kHz. The FREQ control also works in conjunction with
the ‘Q’ switch. With the ‘Q’ switch in its down position the
bandwidth of the variable frequency control is set to 1 octave. With
the ‘Q’ switch in its up position the bandwidth is half octave which
gives a more peaked and focused effect.

DRIVE & +10dB SWITCHThe DRIVE control adjusts the degree of distortion added to the
mid frequency band selected above. The range of this control is
very wide going from almost no distortion on minimum (this is
also dependent on the setting of the INPUT control) to well over
the top on maximum. The +10dB switch works in conjunction with
this control giving a minimum of +10dB boost to any setting of the
DRIVE control providing extreme distortion effects with long
sustain.
