Wondering how to get the most out of your Fender amp? Our columnist shares his top amp-and-cab combinations to boost your tone and volume for any situation.
Let's talk about speaker cabinets. If you have read my previous columns or been to my website fenderguru.com, you’ll know how much I value knowledge about speakers. Speakers affect the tone and volume vastly in guitar amps, and an extension cabinet is a smart and cheap way to get your tone right at practice, live gigs, or in the studio. In this column I will share my favorite amp and speaker cabinet pairings. As usual, I will refer to the classic black- and silver-panel Fender amps, which many of us enjoy.
I have plenty of extension cabinets lying around at home, including many that I have built myself. I use them across all the amps I have, with both combos and piggy-backs. Some are intended for British-style cranked tones, and some American vintage-style. Some cabinets have efficient and chunky speakers that can double the punch and spread on large stages, which I use when the speakers in my combo amps are not enough. More (and louder) speakers enable me to create a representative guitar tone on stage that everyone can hear well. “Sound good, play good” is one of my philosophies. Extension cabinets can serve other purposes too, such as lowering the volume for more breakup or mixing several speakers for a more complex and rich tone. There are so many interesting tone flavors that you should experiment with.
“The impedance mismatch gives me Hendrix’s JTM45 tones at reasonable volumes.”
Here are my all-time favorite Fender amp and cabinet pairings. All speakers are 8-ohm and wired in parallel, if not explicitly mentioned otherwise.
Black-Panel/Silver-Panel Bassman and Bandmaster
These amps’ flexible 4-ohm output transformers allow many different speaker configurations. The original 2x12 cabinet is very loud and chunky. If you use a 3x10 or 2x10 open cabinet with modest, vintage-style speakers, you will sound more like a Super Reverb, Vibrolux, or tweed Bassman. The 50-watt Bassman can push a 2x15 or even a 4x12 (ideally 16 ohm, with 8 ohm as second best) if you are in a “Who’s your daddy?” mood.
My favorite cabinet with the Bassman is a 1x12 semi-closed cabinet loaded with an Eminence Reignmaker with a 9 dB built-in attenuator. The impedance mismatch gives me Hendrix’s JTM45 tones at reasonable volumes.
Champ and Blues Junior
In their combo chassis, these amps can sound small and boxy. If you use a 1x12 semi-closed cabinet and disengage the built-in speaker entirely, you can take these amps to gigs. I recommend at least a Deluxe Reverb cabinet to get enough punch and spread.
Deluxe Reverb
With the 22-watt Deluxe 1x12, you can add an additional 1x12 for more spread and punch. If you replace the amp’s 6V6 power tubes with 6L6s, you have more power—roughly 30 watts—and can add a 1x15. Always remember to adjust bias when replacing power tubes.
Princeton Reverb
The small output transformer and inefficient phase inverter circuit limits the Princeton Reverb’s dual 6V6s to only 12 watts, with a flabby, loose low end. Therefore, I find the Princeton too weak to add an extension cabinet unless you disengage the built-in 10" speaker. Then it makes sense to use a 1x12 or 1x15 semi-closed cabinet for more punch and spread. This produces a wonderful, warm tone with significant breakup at modest volumes. A cool trick is to pull both 6V6 tubes and insert a single 6L6 for class-A operation and lots of distortion. When I use the 1x12 Eminence Reignmaker-loaded cabinet mentioned earlier, I get full tube distortion at almost bedroom level.
Vibrolux Reverb and Pro Reverb
The flexible 4-ohm configuration makes these amps perfectly suited for a 1x12 or 1x15 extension, for more spread and a mix of tone flavors. If I want to go really big, I disengage the inbuilt vintage-style speakers and hook up my Bassman’s 2x12 closed cabinet. Be aware that the small output transformer of these amps will limit the low end response.
Vibroverb
The undersized power transformer limits this amp’s low-end response. I don’t fancy adding another speaker because it gets too flabby with a 100 percent impedance mismatch.
Super Reverb
I rarely use extension cabinets with the Super Reverb because it’s already loud and punchy. On the contrary, I often disengage two of the four speakers to lower the clean headroom and volume. If you need more spread and send the sound in several directions, you could easily add a 1x12 cabinet and get a balanced and reasonable distribution of the amp’s 40 watts to all five speakers.
Twin Reverb
For those crazy players who need more from an 85-watt Twin, you can add an additional 1x15, with a resulting 50 percent impedance mismatch. Adding a dual 12" or 15" cabinet won’t make it louder since the impedance mismatch increases to 100 percent, which is the maximum I recommend.
Our columnist is a Fender die-hard but finds thrills in an inspired modern alternative: the Victoria Victorilux.
I am extremely loyal to vintage Fender amps. I love their clean and transparent tones, and how their simplicity makes for amplifiers that are not only collectable but serviceable. I do play other guitars and amps besides Fenders, although I have to admit that I always measure them against the brand and often try dialing them to a sound as close as possible to Fender tone. But this month I want to share a story about a Fender-inspired amp that I love: the Victoria Victorilux.
Victoria has had great success with their point-to-point-wired amps based on classic designs—with a twist. Their long customer list of influential musicians and weekend players proves they’ve done something right. Who doesn’t want a new, robust, high-quality amp that looks and sounds vintage?
My love of the Victorilux started in 2011, when I got to try one for the first time. It was my brother’s, and he showed me a long email thread with company founder Mark Baier discussing different speaker and tube options. I was impressed. My brother’s amp was a 3x10 combo loaded with Jensen P10R speakers. It had dual 6L6GC power tubes and a 230V power transformer. Other speaker configurations were also offered by the company including 2x10, 2x12, and 1x15. Today, Victoria offers Eminence speakers instead of Jensens, according to the company’s website. I really like Eminence Legend 1058 10s and Legend 1518 15s because of their full tone and ability to handle high power without losing touch-sensitivity.
I describe the Victorilux as a Fender-black-panel-style amp in a tweed enclosure with brown-panel charm.
I describe the Victorilux as a Fender-black-panel-style amp in a tweed enclosure with brown-panel charm. As with Fender tweed amps, the chassis is placed vertically in the cabinet, which is robustly constructed with finger-jointed solid pine. The speaker baffle board is Baltic plywood. The controls consist of two 1/4" inputs, volume, treble, mid, bass, reverb, and speed and intensity for the tremolo. With just a single channel, there are fewer things that can fail. The circuit component layout is tidy and takes no shortcuts, and everything is coupled and fitted tightly.
For me, the Victorilux was love at first sight. And that deepened when I heard it. I expected the amp to sound something like a Super Reverb: good and clean. But I was surprised by how fine it sounded at low volumes. It had a sparkling clean-yet-lush-and-warm voice even at the quietest bedroom levels. The EQ spectrum seemed wider than I was used to with older Fender amps—especially for the mid control. I have seen a few Victoriluxes without mid knobs, and I strongly recommend trying one with mid control, since that dial can change the amp’s character between a mid-based British voice and an American scooped tone. With the mid knob set high, the Victorilux starts breaking up surprisingly soon for a dual 6L6GC amp. Lowering the mids will take you back into Fender-black-panel land.
At that first meeting, I was quickly able to dial in a nice tone—as can be done with a vintage Fender. But when I turned up the volume, it didn’t sound Fender black-panel at all. The amp broke up earlier and was more aggressive, with more sag and compression—thanks to the Victorilux’s cathode bias design, which reduces clean headroom. I guess Baier was inspired by the early breakup characteristics of small Fender tweed amps when he chose cathode bias for the relatively high-powered Victorilux. Cathode bias is a less efficient power-amp design compared to fixed bias. All black-panel-era amps and the bigger tweed amps had fixed bias, to maximize clean headroom.
The original Jensen speakers in this amp have been replaced with a trio of Webers for a more powerful and chunky sound, with firm, well-defined bass response.
I also expected the reverb to be lush, but I particularly liked the smooth and gradual knob response. The tremolo could nicely sweep deep and slow or very fast. To summarize, I found the Victorilux to be a brilliantly designed amp that contains the best inspirations from Fender’s tweed and black-panel eras.
I later tried a set of Weber speakers in the amp: two alnico 10A150s in the bottom row and a 10A125 on top. That made it much more powerful and chunky, with firm, well-defined bass response. For those who play in power trios with a loud drummer, I recommend this speaker setup. You will fill the stage completely with massive guitar tone. Those are my favorite Webers, though the ceramic 10F150 or 10F125 will also do the job.
I hope my experience will encourage the vintage Fender fellowship to try out various amp brands. There are ambitious alternatives out there, and my experience with the Victorilux proves that classic tone can be crafted using well-built modern amps.
How our columnist’s risky purchase turned out to be a dusty pre-CBS jewel.
This month, I’d like to share the story of my 1964 Fender Vibrolux Reverb. It was a really risky purchase that had some big surprises.
In October 2011, a black-panel Vibrolux Reverb appeared on eBay with a short bid time. It was poorly described with miserable pictures and barely any details or description of condition and origin. Normally I walk away from such auctions, but there was something that caught my eye. First, some red on the speaker labels led me to believe they were perhaps OEM Jensens. And while the amp’s faceplate was unreadable, I thought I saw a long pattern of four words with a very short last word, as in “Fender Electrical Instruments Co.,” and not the more common “Fender Musical Instruments.” What if this was a 1964–65 pre-CBS amp and no one else recognized it? In the automated eBay watch-and-bid sniper tool I used back then, I set up a $2,500 max bid to be placed 10 seconds before the auction ended. When I woke up the next morning, I had bought it for $1,860. I felt both happiness and regret. What had I gotten into?
When the amp arrived in Oslo several weeks later, I was thrilled to see an all-original 1964 Vibrolux Reverb with Jensen C10N speakers—highly desirable among Fender amp players and collectors. I pulled out the chassis and noticed a well-preserved circuit board, with the death cap wired to the ground switch and a non-grounded two-prong power cord. The brown electrolytic Mallory DC and filter caps looked surprisingly nice and were not leaking. The resistors on the power tube sockets also seemed to be in good shape. It even had factory-original RCA tubes.
When I woke up the next morning, I had bought it for $1,860. I felt both happiness and regret. What had I gotten into?
If you see a leak on a 30-year-old electrolytic capacitor, I strongly recommend replacing it. Old electrolytic caps can mean little clean headroom and farty bass, since they can’t hold the required DC voltage when you strike a chord and the massive current starts flowing through the power circuitry to the tube plates. But I decided to not replace any tubes, caps, or resistors before testing the amp. And the grille? Wow! I don’t think I have ever seen such a dark brown—and nice—piece of cloth, with just minor rifts.
I uninstalled the speakers and noticed the cones were marinated with a thick layer of dirt, dust, and smoke particles, probably from a long life in smoky clubs and bars. I screwed them back on the baffle without cleaning them. The wood was still whole and robust, but the Tolex had many scars and cigarette burns, and the faceplate and knobs indicated heavy but not rough usage. Surprisingly, the pots rotated very smoothly. All this indicates that an amp has been played on a regular basis. It looked like a true warrior.
I found a 230/110V step-down transformer and flipped power and standby on for a 15-second interval. Without proper grounding, I was careful to not touch any other electrical equipment in the room, since you don’t know what voltage guitar strings might carry when connected to a non-grounded amp. I expected the regular background noise—scratchy pots and pop and crackle from bad tubes—but the amp was dead quiet! I stroked a heavy E chord and got a loud, mellow, and very dark and midrange-y tone. I flipped the bright switch on and increased the treble to 5, which is normally an extremely bright setting on Fender amps.
The dusty speaker cones on these old and inefficient speakers filter out the sharp treble—a truly desirable feature in vintage amps. They really make your guitar and pedals sound smoother and creamier, and this was the darkest sounding Fender amp I have ever come upon. What makes the Vibrolux Reverb so good is the balance between the attack and responsiveness of the lightly driven 10" speakers, and the compression from the smaller power and output transformers. I think Fender nailed it with the size, weight, and power of this 35-watt, dual-6L6GC creation.
Later, I installed a grounded power cord and disabled the death cap and ground switch. I got a 230V high-quality power transformer from Mercury Magnetics. It’s 10 years later, and the amp has, incredibly, never failed me. I play it at carefully selected gigs with the original speakers, tubes, and caps still in place. Someday I might consider installing a 25k mid switch or pot on the back in the ground switch slot. This is a must-have and easily reversible mod for Fender amps lacking a mid-pot. It makes them break up much sooner, with a crunch outside the clean Fender tone borderline.
An important point of this story is that we can’t typically expect this kind of luck with vintage amps. Some maintenance is usually required and will make an amp more reliable and durable. Be sure the electrolytic caps are in good condition, and always bring spare tubes to gigs and practices, or bring a backup amp.
