The captivating design and the particular configuration make this device unique of its kind. Preamplifier, equalizer and overdrive, configurable for single or coupled use, all in a single pedal. Overdrive characterized by a modern sound, rich in harmonics and with a fast attack. To the classic overdrive controls is added the “Bass Contour” which allows a fine adjustment of the low frequency response of the effect. Absolute novelty that makes the pedal suitable for any type of set-up.
The fine tuning of the low frequencies is not an equalizer but a filter built from the same signal of the instrument and mixed with the distorted signal. The result is a perfectly blended sound with an adjustable 6dB low frequency excursion. The preamplifier stage consists of a 3-band cut / boost equalizer and a master volume.The intervention frequencies are shown in the technical description and can be customized by the user during the purchase phase. The combination of the two parts of the pedal allows you to work on the nuances of the sound and optimize the use in different musical genres.
