What instruments does this pickup fit?

The EMG ACS Bajo Cromo is engineered for bajo quinto and bajo sexto acoustic guitars. It mounts in the soundhole with a prewired endpin jack, so installation is plug-and-play.

Does it require an external preamp or battery?

No. The pickup has a built-in active preamp, and batteries are included and ready to use. You simply plug the endpin jack into your amp, interface, or console and adjust volume at the integrated control.

How does this compare to passive pickups?

The active circuitry delivers a much lower noise floor (-96 dBV) and cleaner signal than passive systems, eliminating hum and interference. It also preserves articulation and presence across the frequency range, especially the upper harmonics critical to bajo tone.

What output specs does it have?

Output voltage is 0.5V with 2 kΩ output impedance, designed to integrate directly with standard mixing consoles, amplifiers, and audio interfaces without additional conditioning.

How long do the batteries last?

The pickup draws 220 microamps at 6 volts and supports up to 27 volts DC, allowing extended battery life during normal use. Actual runtime depends on your playing volume and frequency, but the low current draw means long periods between changes.

Do I pay sales tax on this order?

We collect sales tax only on orders shipped to California. Orders shipped to any other US state are charged $0 sales tax at checkout when you buy direct from our website. On this item that is roughly $15 less out the door than the same listed price at a national retailer or on a marketplace. Marketplaces such as eBay, Reverb and Amazon collect sales tax in nearly every state as marketplace facilitators no matter who the seller is, so the same item at the same price costs less bought direct. Free US shipping and 30-day returns are included. Some states ask buyers to self-report use tax on out-of-state purchases.

EMG ACS 6-String Bass Pickup in Bajo Cromo

The EMG ACS Bajo Cromo is an active magnetic soundhole pickup engineered for bajo quinto and bajo sexto acoustic guitars, delivering responsive amplified tone without sacrificing the instrument's natural resonance. Its compact chrome-finished design integrates seamlessly into the soundhole, and the prewired endpin jack with integrated volume control puts mixing capability directly at your fingertips. For gigging bajo players and studio session work, this is a straightforward, reliable pickup solution that cuts through live mixes with clean amplification and minimal hassle.

Active Electronics & Signal Path

Built-in active preamp circuitry ensures a low-noise signal path with a clean -96 dBV output noise floor, eliminating hum and interference common in passive systems. The 0.5V output voltage and 2 kΩ output impedance provide stable integration with standard mixing consoles, amplifiers, and audio interfaces, while the prewired endpin jack houses both the volume control and battery compartment for plug-and-play functionality. On stage or in the studio, you'll get a consistent, hum-free signal from soundcheck through the last note of the night.

Frequency Response & Power Specifications

A 14 kHz resonant frequency captures the upper harmonic content essential to bajo guitar tone, preserving articulation and presence through amplification so your attack and dynamics stay intact in a full mix. The pickup operates efficiently at 220 microamps @ 6 volts with a maximum supply of 27 volts DC, allowing extended battery life and headroom for dynamic playing; batteries are included and ready to use.
