Galaxy Echo Master Powered Base Microphone – 8-Pin – Echo, Roger Beep, VU Meter – Fits Yaesu FT-757GX

The Galaxy Echo Master is a classic powered base microphone widely known for its strong audio presence, onboard echo control, and solid build quality. Originally produced by Sadelta and later by Galaxy, this microphone earned its reputation as one of the best-performing base microphones of its era—and remains highly sought after today.

This unit features top-mounted slider controls for modulation and echo, allowing precise, real-time adjustment without diving into menus or internal pots. A front-facing modulation VU meter provides immediate visual feedback while transmitting, and a Roger Beep ON/OFF switch adds classic end-of-transmission audio when desired.

The microphone has been fully tested by our shop technician and is confirmed to be operating properly. The slider controls move smoothly, and all functions perform as intended.
