$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.

      Terrific sunscreen!
      I found out about the Sun screen from a youtuber who does Amazon favorites videos. At first, I thought she was nuts for advertising a $32 sun screen especially for the size it is. I really wanted an everyday sun screen that wasn't thick and goopy. I don't mind of I'm going to the beach or pool but a lot of them are a little much for every day use. Im trying to be better at protecting my face.. When I came across this I decided to splurge and try it. I hate to admit it but I'm so glad I did! It has a slight scent but nothing over powering at all. Its truly a weightless sunscreen that is perfect! I put it on before work and it doesn't make me look greasy or anything. You could probably use it under make up of you really wanted to, I just haven't tried it yet. My only complaint is the price but I haven't tried anything as good ad this! I've seen Ulta have sales on it every once in a while.

      Soothing, refreshing, and effective for most uses
      I found this sunscreen back when it was still reasonable priced ($10 for a bottle this size) and am now completely 100% addicted as the price continues to rise. Sigh. I don't use this anywhere but my face and neck. Putting this on my face makes me go "ahhhhh". I break out easily, burn easily, and haaaate the feeling of sunscreen. Previously, I used Neutrogena 45 or 55+ ultra-sheer dry touch, and I still use that sometimes when I expect more intense exposure, but the Coola cucumber just feels so much better. I don't actually know if I would burn in cases where I still use my other 45+ sunscreen since I haven't taken the chance. I use Coola for 30-45 minute pool sessions, and hikes between 30-90 minutes. I haven't trusted it for things like skiing, 3 hour hikes, or boating where you get intense sun and a lot of moisture exposure. Buy if you want a lightweight, refreshing face sunscreen for walks in the sun, lounging poolside, or mild-moderate hikes.

      Organic Sunscreen with an Air-Brushed Finish
      I've been using the Coola Organic sunscreen on my face for about 5 years now. I love that it protects my skin without dangerous chemicals. The product has virtually no scent and has a pleasant creamy, but not greasy, texture. An additional perk is that it creates an instant "air-brushed" looking finish to my skin. Note: I have found that you have to shake the tube (especially when new) or else the product emerges a bit watery at first. I've always used the non-tinted formula so I can't comment on how the tinted formula works. Also, the "cooling" aspect of the product seems more of hype than reality. But, over all, this is an excellent sunscreen.
