Magnatone Super Fifty-Nine M-80 Head

I spent several weeks running the Soldano SLO 100 Custom Snake Head through rehearsals, small club gigs and studio sessions to see whether the mystique around this amp holds up in real use. I came in as a player who values touch response, harmonic complexity and a wide but usable range between pristine cleans and saturated lead tones - the SLO-100 delivered on that promise in ways that were both familiar and surprisingly modern.

First Impressions

The Snake Head finish immediately tells you this is aimed at players who want presence as much as tone - it looks like a flagship amp should and the build communicates quality right away. Powering it up, the amp settled into a quiet, glassy clean that cleaned up wonderfully with my guitar volume and then transformed into a dense, harmonically rich overdrive with a twist of sustain that cut through a full band without sounding harsh. The control layout is straightforward - independent Preamp and Master controls for both channels, plus global 3-band EQ, Presence and the added Depth control - and I appreciated the front-mounted channel switch for quick, hands-on changes during studio work.

Design & Features

Physically the head feels substantial but not overbuilt - it sits stable on a rack or cabinet and the faceplate controls are smooth without being fussy. The Custom Snake variant I used retained the SLO-100's hallmark features - two channels with Normal/Bright/Crunch voicings on the clean side, a thick Overdrive channel with independent Gain and Master, an ultra-transparent tube-buffered effects loop with return-level control, a hardwire effects-loop bypass and a variable slave output for direct recording or combining amps. The addition of the Depth control in the power section noticeably expands low-end control, and the improved DC heater and grounding show up as a lower noise floor compared with older high-gain heads I've used.

Build Quality & Protection

The hand-wired chassis and premium components are instantly apparent when you remove the back plate to check tube access - the socket layout is tidy and the transformers feel solid and well-mounted. The Snake Tolex and metal grille are more than cosmetic - they protect the amp surfaces well during transport and stage use, though I still recommend a padded cover or flight case for heavy gigging. At around the mid 40-pound mark, this is not a lightweight head, but the handles and balanced footprint make it manageable for single-person loading in short runs.

Sound & Tone

This is where the SLO-100 earns its reputation - the cleans are crystalline with a musical high-end that never becomes brittle, while the Overdrive channel stacks harmonic content in a way that feels organic rather than artificially saturated. Palm-muted chugs stay tight, single-note leads sing with harmonics and sustain, and the amp takes pedals extremely well when needed - the tube-buffered loop preserves character and the FX return level works beautifully as a boost. The Presence and Depth controls give you a more nuanced power-section and high-frequency shaping than many competitors, which is especially useful when dialing the amp into different speaker cabinets or room acoustics.

Playability & Usability

I found the front-panel layout intuitive for both live and studio use - switching channels by foot or the front toggle is instant and the two-master approach lets you set rhythm and lead volumes independently without surprises. The ultra-transparent effects loop is stellar for integrating modulation and time-based effects after the preamp, and the hardwire bypass is welcome if you want the pure signal path. The included 2-button footswitch and the slave out make the head flexible for a variety of setups, from simple cab rigs to modern hybrid recording chains.

Real-World Experience

In rehearsal the SLO-100 cut through a busy three-guitar mix with the kind of definition you can only get from an amp that balances midrange bloom and top-end clarity. On a small club stage the amp’s top-end shimmer needed only minor Presence adjustment to avoid listening fatigue, and my guitar sat exactly where I wanted it in the mix. In the studio I used the variable slave output into an FRFR cab and an IR-loaded interface - the head translated well to direct recording and captured the core character without sounding thin. The only time I found myself dialing heavily was when trying to match lower-powered boutique heads - you have to respect its headroom and adjust accordingly.

The Trade-Offs

The biggest trade-offs are cost and weight - this is a premium, hand-built American head at a premium price, and it shows in both wallet impact and heft. If you primarily need portable, lightweight rigs or are on a tight budget there are more affordable options that get you close tonally, but you give up the unique interaction of the SLO's preamp and power section. Also, while the amp is versatile, its sweet spot is modern high-gain and high-fidelity rock tones - if you mainly chase vintage British blues cleans, it's not the first tool I would reach for.

Final Verdict

The Soldano SLO 100 Custom Snake Head is a modern classic - if you want forward, articulate high-gain tone with a beautifully voiced clean channel and features that work in both studio and live settings, this amp makes a compelling case. It is expensive and not the lightest head to move around, but what you get in return is an amp that responds to your hands and pedals in a way very few modern heads do - for players who rely on nuance, dynamics and harmonic richness, it is worth auditioning seriously.

I spent several weeks running the Engl E633 Fireball 25 through rehearsals, home-recording sessions, and a handful of low-volume live rehearsals to see how it handles everything from chiming cleans to full-throttle lead tones. My background is in high-gain rock and metal, so I was especially interested in how a 25-watt, 6L6-equipped Engl would balance headroom, feel, and usability for both stage and apartment use.

First Impressions

The Fireball 25 looks every bit the compact German tube head you expect - solid chassis, tactile controls, and a layout that makes sense onstage. My first minutes with it were dominated by the clean channel's sweet top end and the Lead channel's immediate, saturated character - there was a smooth transition between crunchy and full lead gain that felt musical rather than just "louder distortion." The power soak and multi-position attenuation immediately stood out as practical features - I could drive the power amp into breakup at 25 watts for rehearsals and then drop to 5 or 1 watt to record with natural power-amp saturation at bedroom volumes.

Design & Features

The control set is straightforward - independent gain controls for Clean and Lead, a 3-band EQ, presence, a dedicated Lead volume, Mid Boost, and an integrated noise gate with a threshold control. The rear panel includes a tube-buffered FX loop, two speaker jacks, a line/DI output, and dual footswitch jacks for the Z4-style controller, which gives you channel switching, mid-boost, master boost, and loop control. Physically it's compact and light for a tube head, and the bundled Thon case in this package makes transportation safer and cleaner for gigging musicians.

Build Quality & Protection

The Fireball 25 feels well-engineered - the chassis and faceplate are rigid, knobs have a reassuring feel, and the tube compartment is laid out for easy access. The unit I used showed tight tolerances and quality jacks, although as with any tube amp I would recommend protecting it from heavy bumps during transport and keeping it covered when not in use. The Thon amp case included in this bundle is a practical addition and fits the head nicely, giving peace of mind for local gigs and rehearsals.

Playability & Usability

The Fireball 25 is unusually easy to dial in - the EQ is responsive and the Mid Boost gives you a quick cut-through option for solos without wrecking the amp's character. I found the noise gate useful at higher gain settings, though it takes a hair of tweaking to avoid chipping the very front edge of notes. The power soak is a genuine usability win - switching between full, 5 W, and 1 W lets me push the power amp for feel at any volume level, which made both recording and late-night practice much more productive.

Real-World Experience

In a rehearsal room with a 2x12 cab the Fireball 25 cut through the mix with tight low end and focused mids that made rhythm riffs feel immediate and energetic. For leads it has a singing sustain and harmonic clarity that sits well over distorted tracks, and I liked how pedals in front of the amp behaved - overdrive and boost pedals layered naturally without getting lost. For home recording I used the line/DI output and occasional mic captures, and the amp retained its tonal identity through both methods, though I preferred a mic'd 12 for the fattest results.

The Trade-Offs

No amp is perfect - the Fireball 25 is no exception. While I loved the overall tonality, I did notice that some pots and jacks can be more sensitive to dust or contact noise if not treated well, and the onboard noise gate can become slightly aggressive if cranked to max. A handful of users online report rare issues like intermittent volume cuts or tube drift - I did not experience catastrophic failures but I did swap power tubes during my time with it to explore how bias and tube choice affect the voice, and that made a noticeable difference in top-end character.

Final Verdict

The Engl E633 Fireball 25 Bundle is an excellent choice if you want a compact, serious-sounding tube head with real stage chops and home-recording flexibility. I recommend it to players who value a modern high-gain palette but still want usable cleans and studio-capable power scaling - lead players, gigging indie/metal guitarists, and small-studio owners will get the most immediate value from it. Be mindful of tube maintenance and occasional contact issues that can appear on any tube amp, and if you travel a lot the bundled case is a welcome addition that protects your investment.

I spent several weeks playing the Friedman Plex Head through a variety of cabs in rehearsal and small studio sessions to see whether it lives up to the hype - it absolutely nails the dynamic, chimey Plexi feel while adding practical modern touches that make it usable at lower volumes. My background is in gigging classic rock and recording, so my priorities were authentic Plexi tones, responsiveness to picking and guitar volume, and usable stage practicality.

First Impressions

Right out of the case the Plex looks simple and purposeful - clean front panel, tight layout, and the kind of build you expect from a premium amp. Plugging in, the pair of EL34 power tubes and the three 12AX7 preamp voices were immediately obvious in the way the amp compressed and harmonized as I pushed the channel volumes. I liked how the three-way bright switches above each channel let me fine-tune top-end bite without reaching for pedals, and the post-phase master volume preserved the amp's dynamics when I needed to hold back volume in the room. The Variac/low-voltage option is a neat feature for dialing a looser, more saturated Plexi tone without going full tilt on stage volume.

Design & Features

The Plex is a two-channel, 50-watt, all-tube head that intentionally recreates the feel of a 1968 JMP Super Lead while adding modern conveniences - independent Volume controls for Lead and Normal, a post-phase-inverter master volume, 3-position bright switches per channel, and internal channel jumpering. The back panel is straightforward - multiple impedance speaker jacks for 4, 8 and 16 ohms and an IEC mains input, and the head measures and weighs in around 24 x 10 x 8.75 inches and roughly 33.5 lbs, which makes it roadable while still feeling substantial. What I appreciated was Friedman's conservative approach to feature creep - they focused on getting the circuit and parts right rather than loading the amp with digital bells and whistles.

Build Quality & Protection

The cabinet and chassis feel rock-solid - the transformers are USA-made and the finish and hardware are top tier, which made me comfortable hauling it between rehearsals. Tube access and layout are tidy; the amp is assembled in the USA and carries the sort of heavy-duty components you expect at this price point. In my time with it I had zero issues with rattles, intermittent jacks, or noisy pots - it felt like something built to last and to be serviced if needed.

Playability & Usability

Where the Plex really shines is responsiveness - it rewards picking dynamics, and the way the two front-end volumes interact makes tone-shaping feel intuitive. I used both humbuckers and single-coils and found the Normal channel a thicker, darker voice and the Lead channel sharper with more midrange bite - mixing the two (internal jumpering) is where it gets sweet and complex. The post-phase master volume is a practical addition that keeps the amp's character when you need to play at quieter volumes, though I still found the amp happiest at louder levels for fullest touch response.

Real-World Experience

I used the Plex for rehearsal and a few tracked guitar parts - in a live-style rehearsal it cut through a loud band without sounding brittle, and in the studio it recorded beautifully to a close SM57/57+condenser blend. Pedals behave predictably in front of the amp - overdrives and treble boosters drive it in classic ways, but note there is no effects loop, so modulation and delays are best placed in front or tracked in the box. Switching to the low-voltage mode produced a delicious, more saturated tone that felt perfect for late-70s hard rock textures - it’s a real tool for tone hunting.

The Trade-Offs

The Plex is not perfect for everyone - at its street price it is a significant investment and sits at the premium end of the market, which may be tough to justify if you prefer modern convenience features. For players who need an effects loop, channel footswitching, or built-in cab simulation/DI, the Plex leaves those out by design, so you’ll need external solutions for those needs. Finally, while 33.5 lbs is manageable, it’s not light, so if portability and airline travel factor heavily it’s worth considering lighter alternatives or a smaller head.

Final Verdict

The Friedman Plex Head is an outstanding, authentic Plexi-voiced head with careful modern refinements that make it usable in contemporary rehearsal and studio contexts - it breathes, responds, and sings in ways few Marshall-recreation amps do. I recommend it for players who want a real-play feel and classic British tone with practical volume control - especially classic rock, blues, and vintage-inspired hard rock players who value tone over onboard extras. If you need an effects loop or want a bargain, look elsewhere, but if you want the feel and response of a great JMP-style Plexi with Friedman-level build quality, the Plex is a very strong choice.
