Jackson Audio Silvertone Twin Trem
jackson.audio
Almost any effect can be used subliminally or to extremes. But tremolo is a little extra special when employed at its weirder limits. Unlike reverb or delay, for instance, which approximate phenomena heard in the natural world, tremolo from anything other than an amp or pedal tends to occur in the realm of altered statesāsuggesting the sexy, subterranean, and dreamy. Such moods can be conjured with any single tremolo. Put two together, though, and the simply sensual can be surreal. Modify this equation by mating two distinctly different tremolo types, and the possible sound pictures increase manifold.
The all-analog, U.S.-built Jackson Audio Silvertone Twin Trem accomplishes this by combining a syrupy harmonic tremoloāthe likes of which youād hear from an early-1960s brown-panel Fender ampāand an optical tremolo like that in a Silvertone 1484 Twin Twelve amp or black-panel Fender. Both effects can be used independently, but itās when the two are blended that the Twin Trem shines.
Doppelganger Effect
The Twin Tremās optical and harmonic circuits are obviously not identical twins, but each is operated via its own 3-knob array consisting of speed, depth, and a smaller volume knob that will boost or cut the output of the individual circuit. Both tremolo types modulate at speeds slower than what you hear in amplifier equivalents. I donāt have a Silvertone Twin Twelve tremolo on hand for comparison. But the slowest speed from a mid-1960s Fender optical tremolo matched the rate of the Twin Tremās optical circuit at about the midpoint of its range. At its slowest, the optical side will cycle through minimum and maximum volume in just a little under a full second, which feels molasses-slow, stretching and enhancing the ramping effect. Maximum speeds on the Twin Trem are closer to the maximum on the old Fender. But thatās still a pretty rapid modulation rate and the Twin Tremās range-y depth controls make fast modulations sound extra alien.
If youāre sensitive to such things, the dedicated volume controls are great for overcoming the perceived volume drop that goes with any tremolo. Thereās much more gain available than what you need for that purpose, and slathering on the volume gives the pulses a burly quality thatās tough but can obscure some nuance. The ability to create disparate volumes for each circuit means you can slightly foreground one tremolo type or the other, opening up an even wider tone palette and highlighting unique interrelationships between modulations.
Double Shots Make Dizzy Daze
The Twin Tremās optical tremolo side (if you open up the back you can watch the pulsing diode that activates the opto-resistor) exhibits the throbbing tendencies one associates with black-panel Fender amplifiers. In fact, the Twin Trem sounds uncannily like the old Vibrolux I used for this test, but with more speed, range, and intensity. On its own, itās a convincing stand-in for a 1960s Fender, Gibson, or Silvertone circuit.
One of the coolest things about the harmonic tremolo is how it often doesnāt sound like tremolo at all. In a harmonic tremolo circuit, high and low-frequency bands are split and volume-attenuated out of phase from each other, creating a bubblegum elasticity in the modulations. At slow speeds the harmonic tremoloās phasey attributes take center stage (clip 1). And though the modulation texture is less swirling than what a simple phaser produces, the more vowel-like pulses lend a sleepy, mysterious aura to the modulation.
Though I did not use the pedal in stereo, I did utilize the effects loop, inserting a delay between the harmonic and optical tremolo, creating a little extra wash in the harmonic tremolo sweeps (clip 2). You can go crazy with possibilities here: How about inserting a multiple-tape-head-style delay for maximum syncopated mayhem? But the most traditional application for the effects loop is to simulate the reverb-into-tremolo order found in many mid-1960s amps. Again, itās a great option when you need ā60s reverb/tremolo combo amp vibes and thereās no such animal around.Clip 2, which showcases the Twin Tremās effects loop, also captures the two tremolos working together. And even at this fast-twitching speed you can hear the phaser-like wash softening the front end of the harder optical pulses that are situated downstream. Some dual-trem settings can produce chaos. But the best ones are thick, eerie, and propulsive in ways that can completely transform a songās ambience.
The Verdict
The Twin Trem is just short of 300 bucks, and itās easy to rationalize such a significant expense when you consider that you get two distinct tremolo sounds that you can mix, match, and switch between very readily. Maximizing the investment probably requires a little extra thirst for the unusual. Not all combined settings are money. Some rhythmic syncopations will drive you batty, and without the benefit of digital control you can disappear down little rabbit holes trying to find an elusive, perfect subdivision between modulation tempos or replicating a texture you found the previous week. These are very minor traps, however. In general, the Twin Trem is forgiving and easy to use. And if you get in a meditative place with the pedal, and let it do the driving from time to time, the riffs will practically write themselves.
Featuring a preamp and Dynamic Expansion circuit for punch and attack, plus switchable amp simulations.
"Like a missile seeking its target, Heatseeker will give you the explosive sound of rock! Inspired directly from the gear setup used by Angus Young,it features the most important sonic elements to match the tone of the short-pants-rock-God.
Itās no secret that a major role to his sound, along with the Marshall-brick walls, played one of the first wireless systems for guitar that quickly became a classic among guitar greats, the Schaffer Vega Diversity System."
The preamp along with the Dynamic Expansion circuit found in the wireless transmitter/receiver gave it its distinct sound. Besides boosting the signal, the preamp tightens up lower frequencies and slightly accentuates mid frequencies while the Dynamic Expansion circuit enhances the dynamic response and harmonics of the signal giving punch and attack to ensure that it will cut through the mix. Instead of opting for a prefix setting for the Dynamic Expansion circuit as found in the original unit, we have re-imagined our version with the enhanced knob on the Heatseeker to have more control over the guitar toneās dynamic response. Setting it around 10 oāclock is a good starting point to add some extra sparkle. Max it out to bring back to life even the most dull and colorless sounds.
Utilizing an all-analog JFET circuit, running on 27 volts via an internal voltage boost (DO NOT plug higher than 9V DC power supply), we have captured the tone and feel of three British tube amplifiers, synonymous with the sound of rock and roll, with an excellent clean-to-mean dynamic response. With the flip of a toggle switch, you can capture the sound and feel of a JTM45, 1959 Super Lead, or JMP 2203. A smart switching circuit follows the signal path and respective gain stages tuned for each amp and combines them with an actual Marshall style EQ and power amp simula-tion circuit for thundering rock tones. Angus Young usually plugs into Channel 1 or High Treble input of his JTM45s and Super Leads so we opted for that sound when we started visualizing Heatseeker on the drawing board. We have also extended the range of the presence control beyond the original so that the user will be able to match the pedal to any amp or gear setup. The master volume offers plenty of output so that you can also use the pedal as a preamp and plug it into a clean power amp or straight to your DAW. Note that the pedal doesnāt feature any speaker simulation circuit so we recommend using a separate hardware or software guitar speaker simulation when going direct to DAW or a full-range speaker.
A new feature to our booster/drive + amp-in-a-box line of pedals, recreating legendary sounds, is the switchable WoS (Wall of Sound) circuit. We have carefully tuned this circuit at the output of the AMP section of the Heatseeker to open up the soundstage by increasing the output, adding thundering lows, and thickening high mid frequencies. Imagine standing in front of a wall loaded with Marshall amp heads and 4x12 speaker cabinets, grabbing your SG, and hitting a chord. You will be blown away by the sound projection! In combination with the tube power amp simulation and the enhanced circuit of the right section, weāve made sure that the pick attack will be as dynamic as it gets, soĀ„er picking will produce clean and slightly crunchy sounds, and hard picking will give explosive distorted sounds! While primarily designed for Angus Young sounds, Heatseeker will definitely open the door to countless other guitar-great tones that use these Marshall amps and/or the Schaffer Vega Diversity System. Think of KISS, Peter Frampton, and Van Halen to name a few.
Like our other dual overdrive/amp-in-a-box designs, Heatseeker features a passive effects loop to give you the option to connect your beloved pedals between the preamp/enhancer and amp-in-a-box circuit or use the two sections as separate and independent effects when using an external bypass switcher/looper. SND is the output of the BOOST/ENHANCE section, RTN is the input of the AMP section. SND is connected to RTN when no instrument jacks are inserted in the effects loop. Note that all pedals inserted in the passive effects loop are still in the signal chain when any or both sections of the Heatseeker are in bypass mode.
Heatseeker features a power-up bypass/engage pre-set function for the footswitches. You can change the default function by holding down the footswitch(es) during power-up. That way you can select which state your pedal will go to when you plug the power supply. This function comes in especially handy to people who use remote pedal switchers/loopers as they only set the state of the pedal once and then operate from the controller.

Victory The Deputy Compact Guitar Head
victoryamps.com
If a venueās dimensions demand you turn down, you might as well lighten your load.Victory Amps are hip to this trade-off. Their line is now thickly populated with amps that are smaller, quieter, but still sound massive.
The EL86-driven, 25-watt, single-channelThe Deputy Compact Head is the newest of Victoryās mighty mites. Although itās generally lunchbox-sized, The Deputy looks like a proper amp headāeschewing the mostly metal, vented enclosure design used in some other Victory offerings. Created in conjunction with Pete HonorĆ© (known to many YouTube guitar heads as Danish Pete), The Deputy Compact Head aims to span ā60s British-style clean tones and ā70s classic-rock overdrive. Itās truly compact at 15" x 8" x 7.5" and 17.6 pounds.
Dawg Daze
Other than the bijou size, which is not unusual these days, The Deputy stands out for its use of EL86 output tubes. Although it can be re-biased to use the more common EL84, Victory ships the head with a pair of new-old-stock EL86 tubes which are broadly similar to EL84s in character and output powerāthough capable of a little more of it from a little less voltage. They are also relatively available and affordable as NOS components. The preamp is driven by three 12AX7s. Rectification is solid-state.
The straightforward controls include gain, treble, middle, bass, reverb, and master, plus a 2-way bright switch and a 3-way voice switch. The latter is arguably more of a gain-structure switch, though gain, voice, and tone are often used interchangeably in guitar-speak. The ampās lowest gain setting is accessed via the upper position. The middle position stacks another +6 dB of gain on top of that, and the lower position adds upper-mid and treble on top of the extra 6 dB. As for the reverb, Victory describes it as a mix of plate- and hall-type textures, and it is probably meant to sound a bit more contemporary, studio-like, and less specific than a traditional spring reverb.
The ampās back panel includes send and return jacks for the series effects loop, two 8-ohm speaker outputs and one 16-ohm output, bias checkpoints, and a bias adjustment pot. Rather than being cathode-biased like most EL84 amplifiers, The Deputyās EL86s are run in adjustable fixed bias, which delivers slightly tighter, firmer response from any given pair of tubes, while maximizing their output potential (all else being equal). As such, you need to check and adjust this setting when replacing the EL86s or substituting EL84s. The Deputyās circuit is arranged on a rugged printed circuit board, the components are all high quality, and the transformers are U.K.-made.
Hot Lunch
I tested The Deputy with an open-back 1x12 cabinet equipped with a Scumback J75 and a closed-back 2x12 with Celestion M65 Creambacks. I also paired it with a Gibson ES-355, a FenderĀ Stratocaster, a selection of overdrive pedals at the front end, and a Source Audio Collider in the effects loop for delay and reverb. Almost regardless of whatās in the mix, The Deputy is a great-sounding little head. In fact, any sense of ālittleā largely vanishes from consideration once you start playing it. Full, fat, deep, clear, and vintage-leaning, with a character thatās very much its own, The Deputy doesnāt care if thereās a stompbox anywhere in sight, but itās also an excellent pedal platform.
The Deputyās tube complement and Victoryās English origins might imply that strictly Vox-like voices emit from this diminutive head, but the circuit enables many more trans-Atlantic sounds. With the EQ dialed in right and the bright switch engaged, The Deputy will indeed cop AC-style tones on the clean and crunchy side of that spectrum. But the robust preamp voicing and fixed-bias output stageāas well as the solid-state rectificationālend a tautness that enables convincing Fender-like tones when you want them. By dialing down the middle control to around 10 oāclock with the voice in the low-gain position, the gain below noon, and master just advanced from midday, I heard pretty good Deluxe Reverb sounds. Thereās certainly more than just one breed of clean to source.
On the whole, I preferred heavier amp-generated crunch and lead sounds with the voice switch in the middle position, the bright switch off, and a little bump from the midrange control. Set this way, The Deputy lends thickness to a Strat without adding harsh or spiky clipping, while the ES-355ās humbuckers are blissfully muscular and aggressive. With more conservative gain settings, the extra upper mid and high end from the brighter voice add cutting power and a shimmering, cranked-Vox-like character that plays well with many styles. Add digital reverbāwhich moves readily from ājust a touchā to an evocative atmospheric washāand the palette of tones at hand becomes even more impressive.
The Verdict
With an able assist from Pete HonorĆ©, Victory has pulled off another deft design. Itās a toneful performer that can sound and feel bigger than it is. For a single-channel head, itās crazy versatileāwith or without pedals. But if youāre into economy on the equipment and cost fronts, youāre bound to be pleased with how much you can do with this high-quality, diminutive head, a cab, a guitar, and nothing else.
