Fender Pro Junior IV: Highest Rated Guitar Combo Tube Amp Under $500 - 2021.07

Gearank Recommended

The Pro Junior IV appeared on our recommended list for Guitar Amps Under $500 from July 2020 until it was removed in July 2022 due to it no longer being available for less than $500.

It also first appeared on our list for Combo Tube Amps in September 2020 where it remained until August 2022 when it was out-ranked by the Vox AC15C1 and Vox AC30S1 in the under $1000 price category.


The Fender Pro Junior IV is a compact tube amp inspired by classic Tweed tones, and it stands out with its simplicity, having only two chicken knobs for adjusting volume and tone.

This two knob format flies in the face of what most modern amps offer, while still providing reasonable tone variety expected from tweed style amps.

Fender sticks to the classic tube amp configuration, equipping this combo amp with two 12AX7 preamp tubes, two EL84 tubes in the power amp section, and one solid-state rectifier.

This single channel amp drives a 10″ Jensen P10R, and all these components are housed inside a nice looking cabinet, with ’50s-era grille cloth, and stitched leather handle.

While many try to mimic Fender’s iconic tweed tone, might as well get this classic genuine tube tone from Fender themselves.
