Should I build a 5F1 or 5F3?

The Key Differences Between Fender 5F1 and Fender 5E3 Amplifiers

If you’re a guitarist or gearhead, chances are you’ve come across the legendary Fender 5F1 (the famous Champ circuit) and the Fender 5E3 (Tweed Deluxe) amplifiers. These amps have been shaping the sound of rock, blues, and country for decades. While they both have that classic Fender sound, they offer different features and tonal characteristics that make them unique.

In this blog, we’ll dive into what sets these amps apart, why builders love them, and how they could be your next project if you're into DIY builds—especially if you’re in Australia and looking for great parts from Evatco.

1. Circuit Design: Simplicity vs. Versatility

Fender 5F1 (Champ): The 5F1 is known for its simplicity. It has a basic single-ended circuit: one preamp tube, one power tube, and a rectifier. That’s it! You’ve got one volume control and no tone controls, meaning your sound is raw and straight to the point. It’s a great choice for players who love that vintage sound without too much tweaking.
Fender 5E3 (Tweed Deluxe): The 5E3, on the other hand, gives you more flexibility. It has two channels (Bright and Normal), two preamp tubes, and a push-pull power section with two 6V6 tubes. The interactive volume controls between channels give you a lot of tonal shaping, making it more versatile than the 5F1. You can dial in a range of clean to overdriven tones by playing around with the settings, giving you more creative freedom.
Pedal Platform: Both amps provide an awesome pedal platform. This is basically a term used to say that they take a pedal in the front of the amp very well. I have one of each and wouldnt be without one. There is a range of plans out there and each is a copy of the original or simply a slight variation of the original.

If you're an amp builder in Australia looking to recreate these circuits, Evatco stocks everything you need, from transformers to tubes and speakers.

2. Power Output: How Much Do You Need?

Fender 5F1: With around 5 watts, the 5F1 is a lower-powered amp, making it perfect for bedroom practice, home recording, and studio work. You don’t need to crank it too much to get that sweet tube overdrive. If you’re looking for vintage tone at reasonable volumes, this little amp delivers in spades.
Fender 5E3: The 5E3 bumps things up to 12-15 watts. That may not sound like much on paper, but trust me—it’s loud! You get more headroom with cleaner tones at higher volumes, but when you push it, you get that classic tweed breakup. It’s perfect for small gigs, rehearsals, or anyone looking for more versatility without losing that vintage vibe.

Amp builders, you can source your 5F1 and 5E3 parts from Evatco, Australia’s go-to supplier for high-quality amp components.

3. Tone: Raw Power vs. Smooth Dynamics

Fender 5F1: The 5F1 Champ has a reputation for delivering a raw, gritty tone that’s perfect for blues and classic rock. It’s got that midrange punch, a loose low end, and breaks up quickly when cranked. There’s a reason why so many guitar heroes, like Clapton and Richards, have recorded with these amps—it gives you that authentic cranked amp sound at manageable volumes.
Fender 5E3: The 5E3 Tweed Deluxe is known for its warm, rich tone. It has more bass response and smoother highs compared to the 5F1, making it perfect for creamy overdrive and lush clean tones. The dynamic response on the 5E3 is amazing—it reacts to your playing, whether you’re picking lightly for clean sounds or digging in for gritty overdrive.

4. Speaker Size: Compact vs. Full-Range Sound

Fender 5F1: The 5F1 typically uses an 8-inch speaker, which gives it a boxy, focused sound. It’s part of the charm that makes this amp so special, as the smaller speaker helps it break up quicker. This gives it that signature gritty tone when pushed hard, but don’t expect big bass response or wide-range sound—it’s all about that raw, mid-forward tone.
Fender 5E3: The 5E3 comes equipped with a 12-inch speaker, giving it more low-end and a fuller sound overall. The larger speaker makes it more versatile for different genres and playing styles, from clean jazz to overdriven blues. You get a bigger soundstage and more headroom with a 12-inch speaker, which is why it’s often favored by gigging musicians.

5. Which Amp Should You Choose?

Fender 5F1: If you’re after simplicity, low volume tube breakup, and a raw, vintage tone, the 5F1 is perfect. Its minimalist design makes it a fantastic amp for recording and home use. Plus, it’s an easy circuit for those new to amp building. With 5 watts of power, it won’t blow out the windows, but it will give you authentic Fender tube tones in a small package.
Fender 5E3: The 5E3 is for players who want more versatility. It’s still got that vintage vibe but with more power, headroom, and tonal options. If you’re gigging or want more control over your sound, the 5E3 is the better option. The combination of two channels and interactive volume controls opens up a world of possibilities.

For Australian amp builders, sourcing high-quality parts is crucial. Thankfully, Evatco has a wide range of components for both the 5F1 and 5E3 circuits, making your DIY build easier and more reliable.
