The Imperial All-Tube Preamp pedal delivers Tone King’s legendary MKII amplifier's '50s tweed, '60s blackface, and vintage British rock tones in a compact, pedalboard-friendly format. It features the exact preamp section and phase inverter circuitry of the Imperial MKII amp, as well as Reverb, Tremolo and Attenuation, resulting in a pedal that sings with harmonic richness and blooming touch response. Powered by three 12AX7 preamp tubes running at high voltage, this preamp delivers the amp's sound, responsiveness, and exquisite interaction with your pickups and effects. The onboard, low-latency impulse response (IR) loader (per channel), Headphones, easy integration and expansion with your existing gear, and MIDI capabilities, takes these iconic tones into the new era of guitar playing.

The Imperial Preamp Pedal features two distinct channels, each mirroring the ’50s and ’60s flavors of the Imperial MKII.

British-flavored rock.

The Lead Channel is inspired by the iconic tweed amps of the ’50s’ with the ability to glide between warm articulate cleans and aggressive midrange bark. This channel’s Mid-Bite control adds a further layer of tone shaping, focusing the low-end, while adding high-end presence and gain for a British-flavored rock crunch.

Classic ’60s.

The Rhythm Channel evokes the essence of a classic ’60s blackface combo’s pristine cleans with a touch-sensitive response that transitions smoothly into overdrive.

Built-In Zero Watt Poweramp – Phase Inverter.

The Imperial Pre-Amp Pedal includes the exact phase inverter circuitry of the actual Imperial MKII amp, utilizing one of its three 12AX7 tubes. This built-in “0 watt poweramp” authentically provides the harmonic and dynamic content of the Tone King poweramp section. This revolutionary design is the cornerstone that delivers the ENTIRE Imperial MKII experience right on your pedal board.

Stereo Convolution Spring Reverb & Stereo Tremolo.

Like its namesake amp, the Imperial Preamp boasts foot-switchable spring reverb and tremolo (digital on the preamp pedal) which are assignable to each channel. A signature of the Tone King Imperial MKII tube amplifier, these era-correct effects add dimension and movement while transporting you to a golden age of electric guitar tone.

Tone King Editor Software.

You can assign the Reverb, Tremolo and IR to each of the channels right on the pedal itself, making it a powerful and easy-to-use sonic tool. Tone King offers an Editor software, powered by Synergy, which takes the Pre-Amp’s capabilities to another level, allowing you to fine-tune all of the preamp’s digitally controlled parameters and save them in up to 128 MIDI presets.

Excellent basic polo shirt
Size: X-Large, Color: Olive
Excellent basic polo short-sleeve shirt for business and work. I appreciate the many different colors Amazon provides for this type of shirt online. It also saved me a special trip to the department store. Needed an extra polo shirt right away.

Great fit, looks and quality for the price. I originally bought two different colors to see how they looked. After receiving them, I will buy more. They are so versatile. I’ve worn them with khakis, jeans, or shorts. Great deal!!!

Seems like a good shirt but the large is more like an XL and it it's cut big
Size: Large, Color: Black, Size: Large, Color: Black
Off the bat, here are two photos of this shirt to help you out: (1) My arms are up and it shows you how big the Large version of this polo is. There is room to spare and plenty of sleeve length. (2) I am holding up one side of the shirt at belt level to show you how long the Large version of this polo is. The photo of the GREEN shirt is NOT THE SHIRT ON THIS PAGE. The green shirt is the slim-fit version. It's a perfectly good shirt. The problem is that the sizing is unlike any polo I have. I'm 6' 175 lbs, I would say my body type is over on the thin side. I usually buy size Large shirts. When I put this size Large shirt on, it was much bigger than I expected. I admit, I have been wearing Gap polos for a long time and a few years ago, they went through this process of progressively cutting their polos more and more narrow. At this point, I consider Gap’s polo a fitted polo, and it’s their only polo. In other words, I have only been wearing fitted polo shirts for a long time. I thought I would switch to a more standard polo, save a little money, and buy some of these Amazon shirts. Same size I buy in all casual shirts. Large. I was expecting a looser fit but, to me, this Large was more like an Extra Large. Much bigger than any Large shirt I had worn in a long time (maybe ever?). I can't suggest one buy a medium to compensate because I haven't tried one. I also can't say if washing it would shrink it enough. Maybe if I washed it in scalding hot water and ran it through a dryer on the "surface of the sun" setting, it might shrink enough. I’m going to opt for returning them. Don’t forget to take note of the length of the shirt. It’s long. My Gap polos land a couple of inches below the waistline. These shirts fall much further down (see photo). This is actually great if you tuck it in but not if you don't Bottom line – it strikes me as a good shirt. You just need to know these are big shirts. I’m going to give the slim-fit version a shot. *UPDATE* The slim-fit version is a MUCH better fit for me. It's almost, but not quite, too tightly cut. It is a looser fit than the 2018 Gap polo. It does shrink a bit in the wash. I've added a photo of me in a slim-fit green shirt. Also much shorter in length.

Excellent value, consistent fit, cool, comfortable and durable.
Size: Large, Color: Army Green
I have purchased 20 plus of these shirts in the past six months. The first batch in spring, figuring if any inconsistencies or quality issues arose upon delivery, no problem. Amazon's return policy has always been hassle free. After trying on the fourth shirt and noticing no outstanding flaws or differences, all were simply opened, laundered and hung on a hanger. The material is 100 percent cotton, but assuming they are removed from the dryer immediately (medium heat) - no ironing necessary. No appreciable shrinking is observed and no outliers in the batch. My sport shirt size is men's US large regular fit. Other relevant sizes - 17.5 inch neck, 46 inch shoulders, 34 inch sleeves and 36 inch waist. Overall fit of these shirts is of appropriate roominess without bagginess. Shirt tail length is spot on, work dress code requires tucked in, and they stay tucked in. Casual requires not tucked in, and unless I am reaching for the sky with both hands while on tip toes, the shirt tail/ belt line is not breached. The sleeve length could have been extended by an inch since they taper to an elastic cuff, requiring that the sleeves are pulled back to original position following an extended reach. But given the choice, the sleeves as is are preferred over a straight cut without the elastic cuff. As an upgrade to the T shirt appearance of the shirt tail when not tucked in, the side seams end with a reinforced, one inch inverted V, a feature not typical in this price range. To date, durability has not been an issue. Fraying, fabric pilling and fading have not occurred. It is quite difficult, if not impossible, to differentiate the age of two duplicate color shirts purchased in two separate batches. Again, excellent value, consistent fit, cool, comfortable and durable!
