## Overview

The Guitar EQ-7545R is a compact 4-band equalizer preamp system designed for acoustic and cigar box guitars. Featuring a rod-style piezo pickup, it offers precise tonal shaping with bass, mid, treble, and presence controls, powered by a 9V battery. Its automatic off-circuit jack preserves battery life, while the slim design fits standard guitar cavities for easy installation. Perfect for musicians seeking enhanced amplification and tonal clarity on stage or in the studio.

## Description

This is a pre-amp unit, perfect for mounting directly into the side of your standard acoustic guitar or cigar box guitar. For standard acoustic guitars, this Curve pre-amp gives you an on-board equalizer and volume control and helps boost and clarify the signal before it goes to your amplifier. For cigar box guitars, using a FLAT pre-amp is guaranteed to make your CBG sound better, compared to wiring a piezo straight to a jack. The rod-style piezo can be built to go under the saddle on standard guitars, and can be built into a bridge or placed directly under the bridge for optimal vibrational pickup on cigar box guitars. Specifications: Flange measurements: 4 1/16" L x 1 3/4" W Fits a hole of size: 3 3/4" L x 1 9/16" W Presence Control: ±12dB at 8KHz Bass Control: ±12dB at 600Hz Middle Control: ±12dB at 600Hz Treble Control: ±12dB at 2.2KHz Input Impedance: 10MΩ Frequency Response: 20Hz - 20KHz Power: 9V alkaline battery (not included) Pickup dimensions: 4 x 1.9 x 2.4inches Package List: 1 * 4 Band EQ Equalizer 1 * End Pin Jack 4 * Mounting Screws 1 * Screw Cap If you have any question please contact us, we will solve it for you quickly.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect For Vintage Phonograph
*by M***S on April 23, 2021*

Greetings, this may sound weird. . . . I restore antique phonographs (and vintage Reel-to-Reel tape recorders) that typically have ceramic / crystal cartridges (pickups). This device is PERFECT for matching ceramic cartridges to vintage electronics. The output is line level (-10dB), but workable with high impedance (vacuum tube) amplifiers. I bought one to experiment with. It worked so well - I bought many more. This particular install I use for ingesting transcription discs (lateral or vertical cut) for restoration and archiving.Because this little amp is designed to amplify a piezo pickup (piezo Is crystal afterall) it's perfect for vintage ceramic cartridges.-Tim, Genuine Effection Sound Recorders.
