เอฟเฟค Nux Boost Core Deluxe เอฟเฟคบูส
Boost Core Deluxe integrates two circuit forms of RC Booster and AC Booster and adds a circuit similar to Treble Boost before these two Boost circuits which can be amplified at full frequency when switched to Spark mode through a 3-way toggle switch in case of overdrive increasing the brightness of the sound.
The Clean mode (RC Boost) retains a very transparent Boost signal just like the original RC which is very suitable for pushing the first-stage tube of the vacuum tube amplifier. Use the high and low bass EQ to tweak the sound of the tube amplifier.
The Dirt mode (AC Boost) can increase more gains (asymmetric diodes cutoff to produce overdrive sound similar to vacuum tube amplifiers) but remove some excessive high frequency harshness using RC filter. Two high- and low-frequency EQ controls of the Baxandall type further shape the enhanced overdrive sound of various frequency bands.
In the Spark mode a high-pass filter is used to simulate the frequency response of Top Boost. Through the AC circuit the classic tone of Top Boost is obtained which is a very prominent guitar tone.
Note: Maximum amplification 35dB
