NostalgiTone AmpEQ
Description
AmpEQ is an active EQ preamp designed to shape your tone without sacrificing clarity. Featuring up to +26 dB of adjustable gain and active Bass and Treble controls, AmpEQ delivers both boost and precise tonal shaping while preserving the natural character of your guitar, pedals, and amplifier.
Its active Bass and Treble EQ provides true boost and cut capability, allowing you to add warmth to brighter guitars, tighten the low end of darker-sounding instruments, or enhance clarity and presence while preserving the dynamics and character of your original signal.
Alternatively, when placed in an amplifier’s effects loop after the preamp stage, AmpEQ becomes an effective tone-shaping tool for fine-tuning your amplifier’s response to different rooms, speakers, and playing environments without increasing preamp gain or changing your amplifier’s core character.
