If I were recommending it as something to emulate, then that would be different. BIAS AMP 2 is probably closer, but that's attempting to model more than just the distortion component. Is it anything like a real amp? Not really. Also, it has some guitar Compared to what though? I think the tone is far less "digital" than Shaper or Grind. If you have access to a higher-quality streaming service, I would recommend listening there. Side note: This video was posted in 2009. Either way, if your exploration into electronics leads you to finding a good way to emulate it, that would be rad. The Rat was often used in 80s metal with chorus and reverb, so this will be an example of the sound it has been used to achieve, rather than a pure demonstration of its tonal characteristics.

But the middle position of the distortion knob on a Rat, is like the highest position on another pedal. At a low enough setting, maybe it could sound like the John Mayer jam. I think the key characteristic is that dirty, resonant, metallic high end. When I think of the Rat tone, the first song that comes to mind is "Cult of Personality" by Living Color, famously featured on the soundtrack to Grand Theft Auto: San Andreas. I don't know if it's special among distortion algorithms as a whole, but it's got something going on that the other iOS options lack.Īnd regarding the Rat, I assumed you would already be familiar with it, but I'll give you an example of a song. So I just thought it's worth knowing about. I only brought it up because it sounds closer to "real distortion" than the other iOS apps, and I mean specifically the ones for iOS. This RAT sound is like a more piercing version of the pedal John Mayer uses when he plays Regarding Eventide MangledVerb, I don't think MangledVerb sounds anything like a Rat, nor do I think it sounds incredibly close to analog distortion in general. I looked it up and found Brian Wampler, who is awesome, explaining how it works: That distortion sound at 0:20 in the video link above is the sound you recommend we should try to emulate? Here's a minute-long demo, skip to :20 for the guitar distortion preset. I thought that might be worth mentioning. The new MangledVerb is arguably the only app with a really natural sounding distortion algorithm.

I got that line from the Wikipedia page, I don't actually know what it means yet. The distortion is produced using a variable gain circuit with diodes shorting the output to ground at a certain voltage level to produce hard clipping of the input waveform. The Rat pedal has been recently discussed in the JimAudio Pure Acid thread, and apparently it's also popular for acid. I'm not sure if this would be outside of the scope of your new app or not, but I'm a big fan of the "ProCo Rat + Marshall" tones.
