Product details
Studio-Inspired Acoustic Tone, Wherever You Play
The Yamaha THR5A is a compact desktop amplifier created specifically for acoustic-electric and Yamaha Silent Guitar players. Instead of treating the pickup signal like a conventional electric guitar amp, its advanced modelling recreates the character of classic condenser, dynamic and tube microphone setups—helping an amplified instrument sound more open, natural and dimensional.
Dedicated nylon-string and electric-guitar clean modes expand its versatility, while compression, chorus, delay and reverb provide polished, recording-inspired ambience. Twin full-range speakers, USB connectivity and AC or battery operation make the THR5A a refined solution for home practice, songwriting, recording and travel.
Signature Features
Five Acoustic-Focused Voicings
Condenser, Dynamic and Tube microphone simulations are joined by dedicated Nylon and EG Clean modes for a broad range of amplified instruments.
Designed for Acoustic-Electric Instruments
The signal path is optimised for the clarity, transients and natural body of acoustic-electric and Yamaha Silent Guitars.
Blend/Gain Control
Balance the direct pickup character with the selected microphone simulation, then set the response to complement the instrument and playing style.
Studio-Grade Effects
Compression, chorus, delay and reverb options add control, width and ambience without requiring a separate pedalboard.
Wide Stereo Sound
Two 8 cm full-range speakers and Yamaha Extended Stereo Technology create a spacious listening image from the compact enclosure.
USB Recording and Playback
Connect to a computer for a streamlined home-recording workflow, stereo playback and deeper sound editing through compatible software.
AC or Battery Operation
Use the supplied adaptor or compatible AA batteries for approximately six hours with alkaline cells or seven hours with nickel-metal hydride cells, depending on conditions.
Compact 2 kg Format
At just 271 × 167 × 120 mm, the THR5A fits easily into a home practice area, writing room or travel setup.
Frequently Asked Questions
Q.Which instruments suit the THR5A?
It is designed primarily for acoustic-electric guitars and Yamaha Silent Guitars, with modes that also support nylon-string instruments and clean electric-guitar playing.
Q.What are the five sound modes?
The front panel offers Condenser, Dynamic, Tube, Nylon and EG Clean. The first three simulate different microphone characters rather than requiring an external microphone.
Q.Does it have an XLR microphone input?
No. The THR5A provides a standard mono instrument input. Its microphone modes are tonal simulations applied to the connected instrument signal.
Q.Which effects are available?
Front-panel choices include compressor, compressor/chorus, chorus, delay, delay/reverb and hall reverb. Compatible THR Editor software provides additional processing options including flanger, phaser, tremolo, spring reverb and noise gate.
Q.Can it be used for recording?
Yes. USB connectivity supports computer integration, and Yamaha lists Cubase AI download information with the supplied accessories.
Q.Does it have Bluetooth?
No. This original THR5A uses its AUX input or USB connection for external audio playback.
Q.Can it operate on batteries?
Yes. It can run from the supplied AC adaptor or compatible AA alkaline or nickel-metal hydride batteries.
Q.Is the THR5A a stage amplifier?
Its 10-watt stereo output is designed mainly for personal practice, writing and recording. For louder ensemble use, a larger acoustic amplification or PA solution may be more suitable.
