Best Paid Amp Sim – Archetype and Plini by Neural DSP

This is an affordable amp sim which is simply one of the most exciting innovations over the past few years. Australian guitarist Plini has made waves for himself with stunning virtuoso techniques which he first demonstrated under the pseudonym halcyon. After he gained the attention of guitar master Steve Vai Neural DSP has now endorsed him as part of their archetype range. The Archetype: Plini plugin was one they designed in tandem with him and it shows. 

Focus on cleanliness and precision even with the heaviest of tones is a feature here. The website gives a rundown of three amps with dedicated clean, rhythm (crunch) and lead classifications. This means even if you’re not a shredding virtuoso yourself you can gain clarity and attention to detail reminiscent of bands like Periphery – who he has opened for – or Plini himself.

Neural DSP has focussed on not chucking in as many FX as possible, instead getting the most out of the ones included. Features like the reverb plugin allow for control not just over classic parameters like wetness and dryness but also more nonlinear, intuitive ones like space and time 


  • Specific amps for clean crunch and overdrive
  • Dynamic FX inc EQ, comp, and reverb for seamlessly blending different parts together, 
  • Digital delay and tape sat 
  • Space and time controls for ultimate soundscape scul[ting 
  • High-quality cab sim with six mic positions and full panning ability in stereo
  • Part of a wider Neural DSP Archetype range 

Price and Availability: listed as 119 euros on their site (128 USD) and available to buy online on Neural DSP’s website. 

Best Guitar Processor Sim VST Plugin – Line 6 Helix Native 

VST plugins which emulate potentially unaffordable hardware can open up a whole new range of options. This is a direct and affordable emulation of Line 6’s physical Helix which clocks in at over 1000 USD, perfect as a budget option or if you own a member of the Helix family and want to keep things consistent.

For the hardware Helix series, line 6 ruled out menu diving and created a pioneering, clean-cut collection of vintage sounds, FX, amps, cabs, mics, and more, focusing on tube amps to give you a classic sound which can work in many situations. Ultimately for 2023, guitar VST plugins which span eras and genres can make it easy to start with something new and the Helix Native makes this reality with its bold selection of offerings.


  • True to the Hardware Helix family of guitar processors 
  • Analogue modelling technology captures the feeling of analogue gear
  • True-to-life circuitry emulates the sound of the amps it is based on 
  • 16 cab options and 23 microphone distances

Best Hidden Gem Guitar VST Plugin – Soundtoys Decapitator 

Some guitar VSTs just seamlessly integrate into your workflow. For example, parallel processing is an absolutely indispensable trick for producing many heavy genres of music involving routing a signal by a bus, adding FX, and blending this back into the dry signal. The Decapitator works well with this and it’s a really unique saturation plugin which the website claims is the ‘secret weapon’ of top mix engineers.

Honestly, it deserves more time in the limelight in 2023, because of how it takes saturation and turns it up to eleven. In fact, the decapitator offers unprecedented scope in terms of distortion from subtle to extreme. Its ‘punish’ button offers ultra-high gain features which bring the visceral results of cranking up real-life analogue hardware to digital modelling and for that it deserves more attention. 


  • High-cut and low-cut filters 
  • Tone and mix dials 
  • Attitude dial and punish button for really warm, gritty sounds 
  • Multi-genre and very versatile 
  • AAX Native and Audiosuite, Au, and VSt formats 
  • Compatible with all major DAWs 

Price and Availability: Arround 200 USD and available from their Pluginboutique – just click here. If you use our link to buy the product, we will get a small kickback. Thank you for your support!
