That was more signal chain theory that I’ve ever read in one sitting.

Sorry 😂. Digital signal processing is one of my special interests so I typically go overboard with it.

• Source of distortion doesn’t really matter, it’s filters
• TS808 cleans shit up, no tubes. Tubes not necessary and probably dont do much in a pedal anyway

Yep that’s it.

• What are you running now for amps and such got get away from the 5150/TS808 combo?

In the “before times”, I used a TBX150 solid state amp alone, and a Peavey 6505, mostly for recording. The TBX150 is a great amp for modern death metal, but it has a parametric EQ. For me, that’s great, but a lot of guitarists don’t like the metal zone because it has a parametric EQ. For both, I plugged them into a cheap birch Seismic cabinet with a Vintage 30 speaker harvested from a Recto cab. Honestly, the biggest factor in the quality of my guitar recordings was switching to that speaker.

At this very moment, since my grandmother moved in, I’ve had to forgo amps altogether for simulators. I actually use either a 6505 simulator (Nick Crowe 8505) or a Fender Frontman (yes, that amp, specifically the AXP Softamp plugin) with the mids cranked up and the cabinet impulse thrown out and replaced with a set of impulses I recorded myself from the previously mentioned cabinet.

The best results I’ve gotten have been with using an EQ before a Boss HM-2 (Buzz Helvetes) set to… however much “HM-2-ness” you want in the EQ depending on what you’re playing, and the smallest possible offset from zero distortion. The pre-EQ is typically a bandpass so I can get more “grinding” and as a cheat for not changing my strings. But, it doesn’t really change the “overall” frequency response of the output of the HM-2, just how the HM-2 “sees” your guitar, so you still get its nastyness. Then the majority of the gain comes from the amp.

If an HM-2 or Metal Zone is too much, I’ve gotten really “smooth” results with using the ProCo Rat as an overdrive. Note that on a ProCo Rat, the Filter (tone) knob “is backwards”; all the way to the left = minimal filtering.

My inspiration for this is really the fact that old school death metal was recorded on shitty gear compared to what is available today, and that some of the magic lies in the fact that it sucks in just the right way. Besides At the Gates who used two shitty pedals, Chuck Schuldinger from Death used a shitty Valvestate and got great results. Most of the old school death metal bands were using Valvestates.

In the past few months, I’ve been experimenting with using the RS-MET tool chain plugin to generate nasty sounding distortion with odd-order Chebyshev polynomials. It initially sounds like a more unhinged Boss HM-2 with no pre or post eq, but since the plugin lets you input the math you want to do, it’s much more controllable. If you use this plugin, you gotta make sure to set the built-in filters to cut off high frequencies that will be aliased, or turn on oversampling, or both. This is included within the plugin, but you have to actually set it. Otherwise, everything just sounds like aliasing, although that’s pretty gnarly too.

So the short answer is: switch out a tube screamer for some garbage piece of gear, preferably something with a frequency response (loosely “tone”) you like and a “bold” distortion. Then, set the pedal so it is giving the least amount of gain while still exhibiting its nonlinearity (minimum possible distortion), then set the amplifier to give you the rest of your gain and cut through the mix. I cannot stress enough that for metal guitars, particularly recording guitars, you gotta set your knobs so that it sounds good in the mix. If it sounds perfect in the room without the rest of the band, I guarantee you it will sound muddy in the mix.
