$489 is your absolute final/total here for the Shift Line Twin MkIIIS, and its power supply is included.

The Shift Line Twin MkIIIS is the 3rd version of this tube guitar preamplifier and cab simulator, which boasts a unique sound, universal connectivity, all in a compact black enclosure and design. The dynamic range has been expanded to achieve maximum gain. As a result, it can go from its renowned clean sound, into crunch and overdrive without external boosting. The Twin has an analog bypass circuit for the digital IR cab sim, and can be 100% analog when the cab sim is not engaged.

The Shift Line Twin cabinet simulation (cab sim) is based on the Impulse Response (IR) convolution technology, which provides a realistic and detailed sound, while preserving the character of the power amp, cabinet, and microphone used to record the impulse.

The Twin comes with two impulses recorded from the Fender Twin combo amplifier. The microSD card slot allows users to upload their own cabinet impulses.

CONNECTIONS:

    • IN is the signal source input.
    • THRU is a buffered output for the unprocessed signal split from the IN jack.
    • SEND/RETURN is a series effects loop for external processing. The SEND out can also be used as an additional output.
    • OUT is the main output designed to connect the preamplifier to a power amplifier (RETURN or POWER AMP IN on combo amplifiers, INPUT on power amplifiers).
    • AUX IN is an external audio input (the signal from the AUX IN is only heard through the PHONES output).
    • PHONES is a headphones output.
    • BALANCED OUT is a balanced output.
    • POWER IN is a power supply input. Shift Line's U.S. compatible power supply is included. The power requirements are 12V DC 650mA.
    • MICRO SD is a microSD card slot.

    CONTROLS:

      • GAIN controls input signal amplification. It can go from a crystal-clear sound all the way to a classic California-style overdrive.
      • BASS, MIDDLE, & TREBLE KNOBS constitute a classic 3-band passive EQ with a mild frequency correction effect.
      • MASTER controls the volume of the signal coming from the OUT jack.
      • VOLUME controls the volume of the signal coming from the PHONES and BALANCED OUT jacks. The MASTER and VOLUME knobs work independently.
      • TOP SWITCH controls the signal’s high frequency harmonic content. The “+” position accentuates the highs and the attack. The ”-” position provides a milder sound by cutting the high frequencies. The neutral position does not affect the signal in any way.
      • GND SWITCH allows to override “ground loops” that can negatively affect the signal when using XLR connections. In the lower position of the switch, the preamp’s “ground” is connected to the signal receiver’s “ground”. In the middle position, the “grounds” are disconnected. In the upper position, the “grounds” are connected and an additional filter is used to remove interference. The optimal setting of the GND switch is selected by ear: there should be a minimum amount of 50Hz hum and interference.
      • CAB SWITCH selects one of the two built-in cabinet impulses recorded from a Fender Twin combo amplifier with two JBL D120F speakers:

        • “A” position selects the impulse recorded by a LOMO 19A19 microphone placed 15cm away from the edge of the speaker’s protective cap.
        • Middle Position, cabinet simulation is disengaged.
        • “B” Position selects the impulse recorded by a Sennheiser e609 microphone placed 25cm away from the center of the speaker.

        When using a microSD card, impulses are loaded from the corresponding folder on the card. The CAB switch affects the signal from the BALANCED OUT and the PHONES OUT but does not affect the signal from the main OUT. 





      LOADING IMPULSES: Using a microSD card

      • Before using a microSD card, make sure it is formatted to the FAT32 filesystem.

      • When the memory card is used for the first time, a “Shift_IR” folder is automatically created on it. The folder contains two more folders (“A” and “B”, corresponding to the CAB switch positions) in which the default impulses are stored. To use external impulses, replace the default ones with your own files. The supported impulse format is 24bit 48kHZ WAVE PCM1, uncompressed.

      • To restore the default impulse files, insert a blank microSD card into the device. This will create a “Shift_IR” folder containing the default files. If no card is inserted, the built-in impulses are used.

      Good Prints for Sublimation
      Model: 500N STD, Model: 500N STD
      After years of using converted printers for sublimation, I finally decided to go with the Sawgrass printer, which is specifically designed for sublimation. The printer turned out to be very nice! I’m particularly happy about the Sawgrass customer service they provide. Follow-up. I ordered the SG500 printer bundle from Amazon, but unfortunately, the prints had visible grid lines. I promptly reached out to Sawgrass customer service, and after a few emails, they figured out that the printer I received was faulty. It was all resolved within a few hours, which was way faster than I had expected. They immediately sent me a replacement machine and the prints are absolutely beautiful for my sublimation projects. Sawgrass customer service is truly amazing! Over the past three months, I have been using the Sawgrass printer and have identified a shortcoming that I would like to share in my review. While the prints produced by the Sawgrass printer are satisfactory, they fall short of the quality achieved with a printer I previously used for several years. This printer required a conversion to sublimation printing. I have sent a note to Sawgrass inquiring about potential solutions to this issue a couple of months ago, but I have not yet received a response. This suggests that the company may not have a viable remedy. You be the judge. I followed Sawgrass recommendations and used the Sawgrass Print Utility, but no matter what changes I make, the converted printer seems to produce prints much more to my liking. Both of the book markers shown were sublimated at the same time. In the future, when I have an order to complete, I will be opting to use the more affordable printer that I converted.

      Sawgrass quality is excellent
      Model: 500N STD, Model: 500N STD
      I've been on the fence with Sawgrass, simply because cost can be an issue, but this past week I decided to put the new Sawgrass to the test against another of my printers which I converted for dye sublimation. I also own the Versiflex. I was on the fence with it initially as well, but I've been using it ALOT and I now have it down to an art. I've made shirts for friends and they were literally blown away at the quality of the print, so. . . yes, it is expensive and yes, you get what you pay for. So. . . I recently received the sublijet ink with my new Sawgrass since you cannot mix inks in a Sawgrass, not even to switch the type of ink for risk of damaging the machine. I'm seriously impressed. I made lanyards, T-shirts, bags and the quality is outstanding. I don't know if I'm going to retire my Epson, but the software to print using the Sawgrass print manager is pretty slick. Lots of options to fine tune your print quality. If you have the cash, buy it. If you don't save up. It's worth it. . . and this is coming from a skeptic.

      Sawgrass is Always Innovating & Improving!
      Model: 500N STD
      I do own a versiflex and already have an expectation of quality and it did not let down. I’ve been running it for a few weeks and I’m honestly proud of what I’ve made. Mugs come out with deep blacks and smooth gradients, coasters are sharp edge to edge, and my poly tees keep their color after the first wash. Setup was fairly simple - drivers, print Manager, paper in, Wi-Fi paired first try. I barely tweak settings; reds, skin tones, and fine text land right without a lot of tinkering. No banding, no weird shifts, and the first print of the day is clean as it has an auto maintenance. For consistent, sellable results, it’s been worth it so far and I highly recommend it.

      If you have a Cricut you need this
      Style: Starter Bundle
      Just what I needed to compliment my Cricut system. Works great, colors are perfect, set up was a breeze, connected to my wireless instantly. Prints look prefect, not all wonky like some can. Value pack was definitely worth the extra $50.
