How to make a Bassman, Twin, or Super Reverb sound more Experienced.
In my July column about achieving classic sounds with various Fender amp and guitar pairings, I briefly mentioned the black-panel Bassman as a tonal gateway for Hendrix fans. Let me go a bit deeper into the topic of chasing Jimi's tones with Fender tube amps.
Most players might think they need a Marshall to emulate Hendrix, and that Fenders are way too clean, bright, and twangy for the sustaining distortion and feedback. That is partly, but not completely, true. Hendrix's crazier lead tones did not come from his amps alone, but from amps and pedals paired in the studio, and he played a lot of Fender amps. I think learning Jimi's picking technique and chordal approach are more important than learning to cop his tone, and, according to biographies, he actually wasn't very much focused on gear. Still, he did create a signature sound and I've developed ways to dial it in.
Early in his career, Hendrix played Fender and Sunn amps, among others. But in most photos that were taken of him onstage, he is holding a Strat in front of Marshall stacks with Super Lead or JTM45 heads. Let's look a bit closer at the JTM45. When released in 1962, the circuit was based on the 1958 to 1960 Fender Bassman—a 40-watt, tube-rectified, dual 5881-tube, push/pull amp feeding four Jensen 10" P10R alnico speakers in a combo-style cabinet. In fact, it was almost identical.
Fender's narrow-panel tweed amps have inspired numerous amp builders and manufacturers, right to this day, and the most famous are probably the 5F6-A circuit Bassman, 5e3 Deluxe, and 5E8-A Twin. In my opinion, they are the best-looking guitar amps of all time and they excel at both clean and crunchy tones.
The Bassman has several EQ possibilities through its airy 4x10 cabinet, with full-spectrum tone and crunch that makes it a great Hendrix-style amp when pushed. The most significant change in the JTM45 was the closed-speaker cabinet with 12" Celestion G12Ms in pairs or quads. Jim Marshall did this to make his amp louder, firmer, and punchier, but it also became more mid-focused. A bigger power transformer added further to the punch and firmness. A 12AX7 in the V1 preamp spot instead of a weaker 12AY7 also made the amp louder but did not change the tone. There were minor changes in EQ cap values and the negative feedback resistor, partly because of component availability. That made the tone controls act differently, with more mids in both the bass and treble pots. Summarized, the JTM45 is louder and has more mids and therefore more distortion. However, I think most players would not tell these amps apart in a blind test if they were played through the same speaker cabinet.
Out of respect for history, you should never remove an original Jensen speaker in a vintage Fender amp unless it's seriously damaged.
So, my advice for getting Jimi's tone with the tweed Bassman, vintage or reissue, is to lower the bass to prevent fart-out, set the volume high for a raw, unfiltered sound, and use the guitar volume to dial back to a cleaner and more mellow voice. If you manage to tame the brightness across the amp, pedals, and guitar, you will be greatly rewarded with a detailed, nuanced response to picking, fretting, bending, vibrato, and other work on the fretboard.
Staying in the tweed era, the 5E8-A circuit Twin is also useful for Hendrix-style distortion, and its 12" speakers will put you closer to a Marshall's solid punch. The Twin doesn't break up as quickly as the Bassman, but you can pull one of the two rectifier tubes to compensate, and get more sag and less clean headroom. The vintage tweed version of this amp has dual 5U4GA rectifier tubes, and the reissue has dual 5U4GBs. Thanks to Fender for not going with a more efficient single GZ34 but keeping it essentially vintage-correct.
Fender has reissued the tweed Bassman and low-power Twin as the '59 Bassman LTD and '57 Custom Twin-Amp. You can put vintage-appropriate Celestion G12M speakers in the reissue Twin for a more classic Marshall-style tone. For the reissue Bassman, I think the best route to a Hendrix tone is replacement WGS 10" Veteran speakers. But a word of caution: Out of respect for history, you should never remove an original Jensen speaker in a vintage Fender amp unless it's seriously damaged.
Finally, we've come to the black-panel/silver-panel Fender Bassman 50-watt and the Super Reverb. Of the three black-panel Bassman circuits—AA864, AA165, and AB165—the AB165 distorts the most. But it lacks a British flavor unless you install a 25k mid pot in place of the fixed 6.8k mid resistor. The mid knob then acts as a crunch control, so it's definitely worth the effort of installation. The black-panel Super Reverb with Jensen P10R or CTS ceramic speakers is quite similar to the Tweed Bassman. If you dial the mids high, lower the bass, and push it really hard … you almost have a Tweed Bassman tone with combined distortion from the preamp, power amp, and speakers. As always, for more crunch at lower volumes you may disengage two of the speakers, use a 12AX7 V6 position phase inverter tube, and pull the V1 tube.

What makes an instrument “worth it” depends not just on quality and craftsmanship, but on your perspective and intentions for it. And the market’s “permission,” too.
Let me start with a story. When I was a kid, you could buy a Teisco Del Rey black-green sunburst guitar in the Sears catalog for $100. I remember clearly thinking that when they made the guitar, they had to get all the details right.
They had to buy the tuning pegs and install them; cut a nut; cut fret slots and fret the guitar; maybe put a truss rod in; carve the neck; make a body; finish the guitar (including spraying a sunburst); install a bridge, pickups, pickguard, and electronics; put strings on it; set the guitar up, and … oh yeah … include a case. What I thought at the time was, “Why don’t you just do it all well?” It wouldn’t be that much harder to do, and the instrument would be something you could play a concert on.
I also found out some time in the late ’80s that the market gives you permission for a product. By my definition, “permission from the market” means that, in general, the product is selling and customers are quite pleased with their purchase. I remember the tradeshow where Audio-Technica released the M50 headphone, and almost immediately it was given permission by the market. It is now an industry standard. Another good example from that period was that the market gave permission to ADATs (which were early digital recorders) and then took it away.
So, the question about gear and prices is: Are you getting your money’s worth? In other words, can you use the instrument at rehearsal, at a gig, in a concert, in a recording studio? I used the Teisco Del Rey as an example because, in a way, they were cool. The market gave permission to sell them, but I’ve never seen one used at a gig, a recording session, or a concert. If an instrument is not worth the money that is being charged, eventually the market will say “no,” and the instruments will be heavily discounted. So, there is a self-adjusting “Is it worth it?” process in the marketplace.
Paul Reed Smith holds court at a clinic.
In my world, whether it’s worth the money is really important. We build instruments that sell all the way from a MAP (minimum advertised price) of $499 to a MAP of $15,000 (which is still 1/20th the price of some vintage guitars). For me, it’s highly important that someone pick up an instrument and play it before they decide if it is “worth it.” When I am at clinics, I very often let someone in the audience play my personal guitar and ask if they like the way it plays and sounds. One of the things I like about buying guitars on the internet is that there’s almost always a return policy if you don’t like the instrument. It’s a safety net that I think is good for the customers in our guitar world.
“There only has to be one thing wrong with a guitar for it to not be usable.”
Another thing I like about the internet is that if you average the blur of all the comments and reviews on a model of instrument, you can get the beginnings of an idea of whether it is worth it. For me, I’m always looking for the product that people missed either in price or that the market never gave permission to.
I recently bought an untouched 1958 vintage Les Paul Special. What was interesting about it was the weight and the neck shape were perfect, but some of the notes were buzzing badly on the neck. We leveled the frets and were kind of taken aback because the frets had never been leveled out of the factory. What we realized is that we never held a vintage Les Paul before that a repairman had not worked on. Was the instrument worth the money the day it was sold in the 1950s? Yes. Was the instrument worth the money as a vintage guitar today? Yes. I got a good deal on an untouched vintage guitar, and it taught me a lot.
I don’t buy vintage guitars as collector’s items. I buy them to understand what the people who made them were thinking the day they were made. You can’t talk to the builders anymore, but the instrument will tell you what they thought. Was the instrument ready for a recording session or a concert when sold? No. So if I had bought it to play, it may not have been worth it to me. In that regard, playing the instrument and not counting purely on reputation are just as important as knowing your “why.” There only has to be one thing wrong with a guitar for it to not be usable. Let’s just exaggerate and say the third fret was in the wrong place…. Big problem. This is kind of the way I look at it.

The T-style Big Mamie has a teak body, roasted-flame-maple neck, and ebony fretboard.
Built with wood from a World War II battleship, this reader’s guitar holds a lot of history.
I love it when guitars and history come together.
My newest guitar, “Big Mamie,” was built with original teak from the deck of the USS Massachusetts (BB-59). This wood saw action in World War II, during multiple campaigns in the 1940s.
I was checking Facebook one day and I saw a post from Battleship Cove (located in Fall River, Massachusetts) where they were auctioning off this Telecaster-style body crafted by Rhode Island luthier Vincent Goulart. The proceeds of the auction would go to helping restore the battleship.
I knew I had to have it. Not only was this a piece of United States and Massachusetts history, but it held a special place in my memories. When I was a kid, my grandparents would take us to Battleship Cove where we’d explore the ships, the submarine, and the historical displays. Later, when I had my own kids, we’d visit and do overnight sleepovers with Scouts. We slept on “Big Mamie” and walked the decks from where this wood was taken.
Daniel had Big Mamie’s neckplate custom laser-engraved with a silhouette of the USS Massachusetts (BB-59), and the dates that can be seen on the battleship’s plaque.
After winning the auction, I was connected to Vincent and he told me the story of how he came to build this body for the restoration fundraiser. He’s a talented luthier, but each of his guitars has to have a unique history/story. This was right up his alley!
We spoke a few times, discussing what I liked to play, and how I’d like the finished guitar to look and sound. In the end, I decided on some standard Fender chrome components for tuners, neck plate, ferrules, etc. For the pickups, I went with Lindy Fralin Blues Specials. The controls are also from Fralin; I decided on the flipped-control orientation with the push-pull mods for the volume engage/disengage and tone caps (.02 MFD and 0.047 MFD, film and oil, respectively).
The vintage/modern roasted-flame-maple neck, with an ebony fretboard, was custom ordered from Warmoth. The neck had an adventure all of its own after initially being lost in shipment. It finally showed up about a week or two after being written off as lost (and after a new order was placed).
“Now I have a piece of history here in my room that I can pass down to my family.”
For the neck plate, I had it custom laser-engraved with a silhouette of the battleship and dates from an onboard plaque. The strap, from Well-Hung Guitar Straps in Canada, fits the patriotic theme. I’m also using oversized strap buttons from Well-Hung.
Over a couple visits to Vincent’s place, he helped me put together all the components and bring “Big Mamie” to life. Now I have a piece of history here in my room that I can pass down to my family. It also gives me a reason to work on my admittedly novice guitar skills.
These pedals are designed with fast response times, versatile routing options, and durable construction.
ISP Technologies has introduced the latest generation of their pioneering noise reduction products: the Decimator X Pedal Series for guitarists and bassists.
Building upon the legacy of ISP’s earlier Decimator pedals, the new Decimator X models utilize cutting-edge patented circuitry to get rid of unwanted noise and 60-cycle hum, effectively eliminating even the most stubborn background noise.
The pedals offer lightning-fast response times and ultra-smooth decay with enhanced tracking technology. If you’re playing staccato, with or without pauses, or if you desire a nice long decay, this technology allows for a natural sound and feel. You can preserve the integrity of your tone, even during fast-paced passages and intricate playing.
Whether you’re running a complex pedalboard setup or keeping it simple, the Decimator X pedals offer versatile routing options to suit your needs. With flexible input and output configurations, you can easily integrate the pedals into any rig, ensuring maximum compatibility and convenience.
ISP offers two variations of the pedal depending on your routing needs. The standard Decimator Xsimply has an IN and OUT jack. You place this pedal in your rig after your gain or noise-prone pedals. The THRESHOLD control is set based on the noise coming into the IN jack.
The Decimator X G-String provides 4 jacks: GUITAR IN, GUITAR OUT, DECIMATOR IN, and DECIMATOROUT. This provides a direct connection from the GUITAR and the direct GUITAR signal is used to control the block of DECIMATOR noise reduction. This allows you to insert your noisy pedals between GUITAROUT and DECIMATOR IN, but the DECIMATOR noise reduction is controlled by the direct GUITAR signal at the GUITAR IN. This configuration offers an important advantage: you can switch from extreme high gain to crunch or clean and never need to re-adjust the threshold control on the pedal, because the direct guitar signal is used to control the noise reduction block.
Built like a tank, the X pedals are housed in a durable enclosure, designed to withstand the demands of the gigging musician and provide reliable performance night after night. Both pedals have a battery compartment for a 9-volt battery and provide a 5.5mm barrel connector for use with a standard external 9-volt DC power adaptor. The new Decimator X carries a $146.72 street price; the Decimator X G-string carries a $236.42 street price.
