Amp Models

At the heart of the Spider® IV 75 experience is a blizzard of artists, producers, engineers and sound designers who spent countless hours creating, comparing and tuning every last amp and effect model.

The result is 16 exceptional amp models that exhibit sophisticated touch response, complex distortions and tube-style compression that breathes like it's emanating from a vintage tube amp. Each model delivers the distinct tonal nuances of a celebrated American, British or European guitar amp, and an exceptional guitar playing experience that you won't soon forget.

  • Clean Red
    Scooped and highly responsive to the player's touch, Clean Red has a beautiful high-end shimmer for one of the best feeling clean tones we've ever made.
  • Clean Green
    Inspired by* some aspects of a Hiwatt® Custom 100, Clean Green emulates the classic clean tones of the late 60s/early 70s. This model is full-bodied with a creamy mid-range and a tight low-end.
  • Twang Red
    Twang Red is inspired by* the sound of a 60s Fender® Blackface Twin Reverb® to produce a classic Nashville spank. Crank the Drive knob for some extra grit and growl!
  • Twang Green
    More aggressive than Twang Red, Twang Green has plenty of cut, punch and attitude inspired by* a 60s Fender® Blackface Deluxe Reverb®.
  • Class A Red
    Brilliant, singing tones with an addictive chime made famous by generations of Brit-rockers, Class A Red is inspired by* a Vox® AC30 Top Boost.
  • Class A Green
    Terrifically dynamic, Class A Green offers boutique-style feel inspired by* some of our favorite amps including the Divided by 13 9/15. Sweet tones on the edge of breaking up give way to seriously throaty Overdrive when the Drive knob is cranked.
  • Blues Red
    The vintage charm of Blues Red is inspired by* the classic tones of a '50s wide panel Fender® Deluxe Reverb®.
  • Blues Green
    Voiced with more attitude than Blues Red, Blues Green delivers a more forward mid-range for a classic rockabilly sound inspired by* the bite of a pint-sized Gretsch® 6156.
  • Crunch Red
    A celebration of the tone used by numerous early metal bands, Crunch Red was inspired by* the signature crunch of a '68 Marshall® Plexi 50-Watt.
  • Crunch Green
    Crunch Green provides a rounded off British-style distortion with a cool mid-honk and great cut. Inspired by* the killer crunch of an Orange® AD30.
  • Hi Gain Red
    Hi Gain Red is inspired by* the infamous brown sound of a '68 Marshall® Plexi 100-Watt with a Variac and jumped input channels.
  • Hi Gain Green
    A modern, scooped metal sound, Hi Gain Green is a refined distortion inspired by* the high-gain mayhem of a Diezel® Herbert.
  • Metal Red
    A one-way ticket to high-gain heaven, Metal Red is tight, punchy and inspired by* the high-gain tone of a Mesa/Boogie® Dual Rectifier®.
  • Metal Green
    Metal Green delivers high-gain aggression with supreme versatility. Sweep the Mid knob to control the character of the distortion! (Set to minimum for fuzz pedal characteristics; set to noon for creamy, modern high-gain tones; set to max to conjure the Class A sound.)
  • Insane Red
    Dialed in for shredding, Insane Red combines the intensity and impact of Metal Red but it delivers more mid-range teeth for that bone-crushing grind. Inspired by* the tone of a Mesa/Boogie® Dual Rectifier® (red channel).
  • Insane Green
    As much input gain distortion as possible short of a complete meltdown! Insane Green delivers an obscene helping of distortion while still retaining tonal definition and character.

Smart FX (up to 4 at once) & More

Line 6 BackTrack + Mic Description

Great songs begin with great ideas. Capture all your revelations, epiphanies and inspirations the moment they strike.

see it work!

Inspiration Insurance

Inspiration is spontaneous, and BackTrack™ + Mic is your guitar’s instant replay button. Easy to use, BackTrack + Mic captures everything you play without ever hitting record.

Always on, BackTrack + Mic begins recording as soon as it detects a signal through the sensitive mic or the quiet 1/4-inch input. Use the 1/4-inch output or headphone output for immediate playback. Just set it and forget it for total inspiration control.

Pressing the “Mark” button designates what you just played as special and separates it for easy review. The Forward and Reverse buttons provide instant recall of marked and non-marked ideas.

BackTrack + Mic can capture up to 24 hours of audio. Saved as .WAV files to a rugged 2-GB flash memory, the audio is easily transferred via USB 2.0 to your computer or recording software for further recording, editing or mixing. The USB connection also recharges the internal battery to its full capacity of over 8 hours.

Sleek and low-profile, BackTrack + Mic fits in your gig bag as easily as it fits into your setup. At rehearsal, at the gig or at home, BackTrack + Mic is fully dedicated to capturing everything you play.

Whats's Under The Hood

BackTrack™ and BackTrack™ + Mic provide intuitive sets of features crucial for capturing all your revelations, epiphanies and great musical ideas.

  • Up to stunning 24-bit, 48 kHz audio
  • Up to 24 hours of audio capture
  • 1/4-inch guitar input
  • 1/4-inch output
  • Microphone with gain control
  • 1/8-inch headphone/Line out
  • Drag .WAV files to your computer via USB 2.0
  • Rechargeable via USB
  • Over 8 hours of battery life
  • Looped playback


What are some of the differences between BackTrack™ and BackTrack™ + Mic?
The biggest differences: BackTrack + Mic features a microphone and a 1/8-inch headphone output, BackTrack does not. Both feature similar features, though, including variable sample rates and bit depth, which are shown here:

Backtrack vs. Backtrack + mic

How much audio can I record?
At their capacities, BackTrack + Mic can capture up to 24 hours of audio and BackTrack can capture up to 12 hours but it depends on the sample rate and bit depth you’ve chosen. At 16-bit/44.1 kHz (standard CD audio), BackTrack + Mic can capture six hours of audio whereas BackTrack can capture only three hours.

What's the big button on top?
That’s the “Mark” button and it’s a great feature. After playing something really special, press “Mark”. Your marked ideas are stored in a separate folder on the flash drive so when you go to drag your ideas off your BackTrack to import them into your recording software, your best ideas will be there waiting for you.

What's with the USB connection?
BackTrack and BackTrack + Mic each have a USB connection for two main reasons:
• To transfer your ideas to your recording software.
• To recharge the battery.

What's the best way to use BackTrack?
There’s no best way to use BackTrack. It’s equally effective at home, on stage, at rehearsal or anywhere else you’re playing.

What kind of file is the recorded audio?
Everything you record is saved as .WAV files. These high-quality audio files will sound great when imported into your recording software.

What's automatic gain control in BackTrack + Mic?
Automatic gain control guards against clipping and overloading, and helps maintain an even level when you’re recording using the microphone.

How do I import files from my BackTrack into my recording software?
It can vary so we recommend that you read your software’s manual but, with most applications, it’s as easy as dragging an audio file right onto a track.
