Bad Cat has won over a lot of players in the time since the California maker built its first high-quality, hand-wired amplifiers in 1999. Then, the company was an unapologetic follower of the Matchless template (which itself borrowed more than a little from Vox). And in fact, the two companies have a lot in common. Bad Cat hired Matchless co-founder Mark Sampson to design Bad Cats at a time when Matchless was on hiatus, and Bad Cat amps from the period were even built with Matchless-branded signal capacitors in their circuits.
If Bad Cat were a bit derivative at first, they consistently evolved, regularly adding features and altogether new designs. The new lineup is totally revamped, however. And while they use old model names like the Cub, Lynx, Hot Cat, and Black Cat model names, each amp has new features and is built around circuit-board construction. Thankfully, the new Black Cat’s many British-flavored sounds are good enough that you probably won’t think too much about details like point-to-point versus circuit-board manufacturing.
Feline Features
Though they are relatively common, even among big name builders, $2K amplifiers with circuit-board construction still give some players pause. But the quality of production I see here falls in line with respected recent offerings I’ve encountered from Mesa/Boogie, Friedman, Tone King, and Soldano.The Black Cat’s revamp means some style changes, too, and some long-time fans may mourn the loss of signature features. The illuminated cat eyes in the logo plate, for instance, are gone, and there’s no EF86 preamp tube in the circuit either.
Still, the revamped Black Cat bridges versatility and simplicity nicely. Bad Cat reduced the Black Cat’s power from 30 watts to 20 watts. But it’s still generated by a pair of EL84 output tubes, cathode-biased for class AB. (Older 30- and 15-watt Black Cats, the Cub, and other models that used cathode-biased EL84s were billed as class A.) The preamp is driven by three 12AX7 tubes, rectification is solid-state, and the reverb is now digital rather than tube-and-spring driven. Hefty custom-spec transformers are mounted on the underside of the chassis.
The clean channel offers tons of glassy chime, plenty of clarity, and great note separation—but with a lovely harmonic swirl that adds depth and dimension and keeps the Black Cat from sounding brittle.
The two footswitchable channels are designated clean and lead, and each has an independent volume and master volume control. They share treble, bass, and cut controls, as well as reverb level and intensity and speed for the bias-modulated tremolo. The back panel features an input for the included 2-button footswitch that handles channel switching and tremolo on/off. There are also a send and return for the buffered effects loop, speaker outs rated at 4 ohms, 8 ohms, 16 ohms, 2x8 ohms and 2x16 ohms, a line out, and power and standby switches.
The rugged cabinet is made from Baltic birch ply and measures 23.75" x 19" x 10.5", and the amp further signals its roadworthiness by way of a substantial 48-pound carry weight. The single 12" speaker is a 60-watt Celestion that Bad Cat says is a variation on the Vintage 30. And though the black vinyl, gold-grille cloth, and gold piping look a touch businesslike, they also tie a visual line to Bad Cats old and new. I think most guitarists will find the simpler light-up logo plate elegantly understated as well.
Nine Lives
I tested the new Black Cat with two very classic and familiar guitars—a Gibson 1959 Les Paul reissue and a Fender 1954 Telecaster reissue. With both instruments, the new Black Cat combo hinted heavily at Bad Cat, Vox, and Marshall tonalities of yore, but with flexibility and range I don’t remember hearing before in Black Cats. The clean channel offers tons of glassy chime, plenty of clarity, and great note separation—but with a lovely harmonic swirl that adds depth and dimension and keeps the Black Cat from sounding brittle. Pushed toward maximum volume, it starts to break up just enough to add bite and texture. But there’s a lot of headroom for a 20-watt amp, and the Telecaster in particular stayed characteristically clean through much of the volume range with the master maxed out.
Like many of its predecessors, the Black Cat is predisposed toward brightness, so I usually kept the treble around 10 o’clock. Easing back on my Telecaster’s tone knob a couple of ticks helped further rein in any ice-picky tendencies. The amp’s cut knob is a huge asset, too, reducing the high-frequency content at the output stage as you turn it up. The tremolo delivers a rich, toothsome throb with great range of speed and depth, and I doubt many players apart from die-hard surf devotees will bemoan the replacement of springs with digital reverb. It sounds evocatively atmospheric without obscuring the core tone.
Switching over to the lead channel, I found delectable Vox drive tones that, at times, verge on Marshall-like without being dead-on plexi or JCM800 copies. Higher-gain sounds are girthy and tend to sizzle and saturate once you situate the volume past 1 o’clock. I probably enjoyed the amp most with the volume knob in the 10:30 to 11:30 zone with the Telecaster, and a hair lower with the Les Paul. At these levels, the Black Cat provided a broader, more organic, and very rock ’n’ roll kind of snarl and bite that you can easily drive to more screaming heights with an overdrive. The low end can get a little loose in higher gain settings, and the shared EQ section sometimes means you can’t dial an EQ profile that works perfectly for both channels. In general, though, it’s cool to have so much range in the lead channel.
The Verdict
If you like Brit textures that exist outside strict Vox and Marshall confines, the new Black Cat is an impressive all-around performer. It offers plenty of rich voices that work for a wide range of playing styles and a well-considered feature set. Build quality is excellent too, even without Bad Cat’s vaunted point-to-point circuit construction. This amp revamp might have some players cherishing their old models. Change tends to do that. But the new cat in town certainly has plenty to offer.

Here’s how to recreate the wide-ranging Epiphone Tone Expressor system on your guitar.
Hello and welcome back to Mod Garage! This is the second part of the Mod Garage look at the Epiphone Tone Expressor system (Pt.1), which is found on the Al Caiola signature model that was built from late 1963 until 1969. After discussing the individual parts and settings last month, we will now bring it all together and see how to use the system in a modern guitar.
In general, it’s possible to use the Varitone/Tone Expressor system in any electric guitar as long as you have enough space to squeeze all the stuff into it. You can mimic a lot of different pickups with this system, but because it’s designed for guitars with humbuckers, that’s how it works best. It’s also possible to use it the other way around and thicken up single-coil pickups instead of slenderizing humbucker tones, and in a future column I’ll talk about what I like to call the “reverse Varitone” system.
For a good and simple overview about all the details from last month, I decided to use a technical drawing to show the isolated Varitone system, so it’s easy for you to identify the individual parts:
Diagram courtesy of SINGLECOIL
This is the basic structure of the Gibson Varitone system with the original values Gibson used. The inductor is a 1.5 H choke. The Epiphone Tone Expressor system is identical but uses a 15 H choke as an inductor. There is a second version of the Tone Expressor system found on the Al Caiola model using the same structure but with different values for the parts. I think this was because different pickups were used, so here are the values for the version of the system in the Al Caiola guitar:
• 15 H choke as an inductor instead of 1.5 H
• Replace the single 100k resistor with a 33k resistor
• .0033 µF cap is used instead of the .001
• .01 µF cap is used instead of the .0033
• .022 µF cap is used instead of the .01
• .047 µF cap is used instead of the .03
• .1 cap µF is used instead of the .22
For best results, use the original Gibson Varitone values along with PAF-style humbuckers—the second version will work best with mini-humbuckers or similar pickups. Depending on the pickups you use, you can experiment and make your own custom version out of it.
“You can mimic a lot of different pickups with this system, but because it’s designed for guitars with humbuckers, that’s how it works best.”
The differences are:
• Using a 15 H instead of the 1.5 H inductor will shift the notches of the filters created by the Tone Expressor system down approximately a fifth for a fuller and fatter tone. Because it is possible to combine several caps with this wiring, choosing a 15 H inductor was also a clever move to keep the tone clearer and more present. You can experiment with this, too. A choke with something between 7 and 10 H will be in the middle of both versions.
• Using a 33k instead of the 100k coupling resistor fits pickups with a lower output like the mini-humbucker perfectly, while the 100k is great for pickups with more output like a PAF.
• The different cap values also correspond to the combination of different pickups and chokes, e.g., for a twangy, Telecaster-type tone, you need a 0.22 µF cap along with a PAF humbucker, while a 0.1 µF cap will do the same along with a mini-humbucker.
So, here we go with the Al Caiola wiring, starting with how it looks in the original guitars from the ’60s. You can clearly see the big, silver-cased choke on top of the electronics as well as the caps, resistors, and the individual switches.

And here is the drawing of the Tone Expressor system I made for you:
Drawing courtesy of SINGLECOIL
All switches are DPDT switches, the tone and volume pots are both 500k audio, and the tone cap is 0.022 µF. A is the coupling resistor (33k or 100k), B is the five 10M ohm pulldown-resistors (one on each switch), which prevent popping noises when engaging a switch, and C is an additional 33k decoupling resistor on each switch that is necessary to decouple the switches from each other when you want to combine their settings. You don’t need that on the Varitone because you can’t combine several caps with the rotary switch.
Besides experimenting with the parameters of the choke, the caps, and the coupling resistor, you can enhance your tonal palette quick and easy by using a pickup selector switch that can engage both pickups together.
In closing, here is a scaled-down version of this wiring, in case you don’t want to use a choke or can’t find one.
Drawing courtesy of SINGLECOIL
As you can see, the coupling resistor (A) and the decoupling resistors (C) are removed. That’s because in the system with the choke (second order filter system), these are necessary, but without a choke, they’re not.
That’s it. Since we are still in the year of the Strat, next month we will have a look into the Fender Cory Wong Stratocaster, so stay tuned!
Until then, keep on modding!
