Positive Grid BIAS FX – Mark IIc Metal Tone

Latest Album Heavy Metal Workout II

Here’s another metal tone I dialed in using the Positive GRID BIAS FX plugin. This time I’m using the their Mark IIc+ amp. This of course is based on the Mesa Boogie Mark IIC amp. I’m going to say this is probably the best amp sim I’ve played through for that classic metal tone and sound. Check out my Mark IIc video below and I’ll go into more details.

BIAS FX Mark IIc+ – Classic Metal Tone

I mentioned classic metal tone above and that’s the first thing that came to mind when I tried out the Marl IIc+ amp sim. In fact, I was immediately inspired to play Master Of Puppets when I plugged in. I’m going to go out on a limb and say this amp can dial in Metallica’s earlier tones pretty accurately.

The classic metal tone is almost something that’s been lost over the years, in my opinion. Now, I think many of today’s metal tones are phenomenal. For the most part, they’re polished and have a ton of clarity. But if a tone is too polished you can lose that raw, metal feel. So I think this BIAS FX Mark IIc amp is great for going back a little.

With the above being said, the Mark IIc certainly isn’t a muddy amp by any means. The tone is has clarity but it also gives you that raw feel, if that makes sense. And this takes me back to it being in line with that classic metal tone, or should I say Puppets’ guitar tone. This is especially heard when you cut the mids down. Cutting the mids was popular for many metal bands back then.

BIAS FX Mark IIc+ Metal Settings

The cabinets are where you can really get diverse in your tones with the Mark IIc+ amp sim from BIAS FX. Of course this is true with most any amp. But I will say that there are some amps that only sound good with a specific cabinet.

I found about three cabinets that sound great with the Mark LLc amp sim. Obviously that’s my opinion. For the video demo above, I used the Treadplate cabinet, their Mesa cab sim, as it gave me that classic metal tone that I was after. Screen shots of both the amp and cabinet settings for my BIAS FX Mark IIc+ metal tone are below:

* My lead tone was about the same with just a slight boost in the gain and mids.

Classic or Modern Metal Tone with the Mark IIc+

I talked a little about the diversity in tones you can get with this amp by using different cabinets. To me, the Treadplate cabinet is definitely the right one for a classic metal tone. Especially if you’re playing Master of Puppets style metal. And this is the cabinet you’re paired with right away when you bring up the Mesa Boogie Mark IIc amp sim.

The Mark IIc+ amp sim can definitely deliver modern metal tones as well. One of the BIAS FX cabinets I tend to gravitate towards with many of their amps is the Thrasher. I’m not certain what this is modeled after but you can get a darker tone with it. Although I don’t down-tune this cabinet seems great for that or if you play a 7 string guitar.

On a side note, I’ve toyed with the idea of getting a 7-string but I prefer sticking with my 6-string, and standard tuning. To each their own, I guess. I do record with a 5 string bass so that makes the overall tone heavier. That being said, much of the metal I listen to is played with 7 string guitars.

I’m sure you could use the BIAS FX Mark IIc for rock tones as well. I tend to think it’s built for metal music though. Diversity in amps (or rather amp sims/plug ins in this case) is certainly not a bad thing. But it’s also good to have amps that specialize in a specific style of music. And most metal music calls for that.

Keep it Metal,


8 Comments on Positive Grid BIAS FX – Mark IIc Metal Tone

    • I don’t recall the exact settings (I only used this amp sim for the video). But my effects are very minimal. The typical noise gate and screamer are there (the standard 0 drive and level at about 7 on the screamer). And I use a little delay for the leads.

    • Thanks man. I only have 1 tone up and it’s my Heavy Metal Workout album tone, using BIAS FX. I think I have screen shots though on my videos for the other tones. My settings are extremely simple. If I can’t quickly dial in a tone I like, I move on to something else. I’m a bit lazy in that aspect!

  1. One other thing – and let me know if you covered it somewhere else – which modeling program do you prefer? I’ve been big time into Positive Grid stuff for the last 6 months or, and had a Line 6 PodXT Live before that. I’m always seeking those coveted Metallica album tones (especially Puppets and Justice) and so far Bias Amp / FX has come the closest (as far as I’ve found). Any advice for getting even closer or your favorite in general?

    • Man tone is so subjective and I honestly don’t spend as much time dialing and tweaking these days. And there’s a huge difference in the tone for just playing or practicing vs the tone you use in recordings because the former may not always sit well in the mix. And a lot of your tone comes though your own style (I had a soundman convince me of this a few years back).

      All that’s said, that Positive Grid Mark C is the closest I’ve found to Puppets!
