Capable Little Tweed Tone Vehicle

From its briefcase size to its 2-knob control set, the Fender Pro Junior is the picture of gigging simplicity. Its single 10-inch Jensen speaker, driven by a 15-watt tube quartet, is all the output and tonal diversity many players ever need. Version 4 of this modern classic features modified volume and tone circuits to better retain the punch, sparkle, and dynamics of your touch, even as you drive it hard. And drive this amp does: spinning the Volume knob past two o'clock adds a beautiful hard edge to chords and melodies. Presentationally, the fullness of Fender's most beloved Tweeds is seen here in the Pro Junior IV: the lacquered cabinet, '50s-era grille cloth, and stitched leather handle all hark back to Fender's most sought-after combos of the middle last century.

What's New in the Pro Junior IV?

Revamped volume and drive circuits

Circuitry enhancements make the Pro Junior IV a more capable tone vehicle than ever before. The tonal response is much more consistent as you dial up the volume/drive. You'll also enjoy greater punch and dynamics as you push the amp to its limits — features that touch players and pedal users are sure to love.

The Pro Jr. IV takes pedals like a champ.
Tweed-era visuals will please any Fender fan.

Real Jensen 10" speaker

Just like your favorite Fender combos of years bygone, the Pro Junior IV packs a 10" Jensen P10R speaker for tight, punchy bass and plenty of top-end sparkle. The retro '50s logo is sure to put a smile on the face of any Fender lover as it peeks behind the vent of the iconic tweed cabinet.

Classic Tweed looks

Fender's Tweed-era combos of the '50s and '60s are some of the most sought-after amps in the world — after all, rock 'n' roll was invented on them. The Pro Junior IV celebrates this period with a host of inspiring appointments. From the lacquered Tweed cabinet right down to the chickenhead knobs, the Fender Pro Junior IV from Sweetwater is an amp that won't disappoint even the staunchest Fender fan.

Perfect grab and go amp!

Love this amp. I was looking for a tube amp lighter than what I already have. It's a simple, one channel amp, with a volume and tone knobs. It takes pedals well and with plenty of headroom to dial up a rock or blues tone. It sounds fantastic! I can really only practice at about "2 " at home. It can hang playing live with a full a band and won't break your back toting it around. The tweed looks really cool too.

New best friend

For the size, and price, every guitar player should have this amplifier. It is incredibly useful for almost any genre of music except death metal. The tones achievable by itself are inspiring. As a platform for pedals, maybe more so…
If you're on the fence, just buy it!

In 30 seconds, I knew I'd keep it for life.

This amp exceeds my expectations, with humbuckers it's an absolute little gain monster. It's very easy to dial in a Billy Gibbons type tone, just put everything on 12!

Rolling off your guitar volume it cleans up quite nicely. This amp is perfect for studio use, and loud enough to keep up with a drummer. Mic'd you could play any show with this little workhorse. Within 30 seconds of firing it up, I knew right then and there if it was lost, I would buy another one instantly.

Sweetwater customer service was as always, above and beyond!

Fantastic amp I wish I could get years ago.

What an amp! Saw this on the Sweetwater list of beginner amps and wish I had this many years ago. Have had for several months, and it still puts a smile on my face every time I plug into it. The simple layout sold me... just volume, tone, your guitars volume, and your fingers. Really sings when driven with creamy OD from the Jensen speaker.

The only con is that there's no speaker out to use an attenuator or cab. With a 2 x 10 it would sound amazing. And yes... reverb would be nice. But the amp is so engaging that you don't really miss it. Gotta say as well... it's made in Mexico, not China, Singapore, etc... a plus in my book for sure. An amazing amp for the price and for what it brings to the table. So good I'm taking it to my amp guy to mod.

This amp is a must have for any guitarist. The tone is great with humbuckers, single coils and P90s .this amp is small in size but big in volume and tone. Works great with pedals too. I LOVE THIS AMP!!!
