Over the last 10 years digital guitar effects and mobile guitar apps have changed the way guitarists play and record. Positive Grid is at the top of the game when it comes to modeled amps and effects.
Positive Grid BIAS FX is a detailed and authentic emulation of analog pedals and studio racks, it has dual custom BIAS Amp Match models integration and dual signal chain.
BIAS FX is equipped with the most advanced DSP sound engine with a beautifully designed interface, it’s seamlessly integrated with BIAS Amp Designer

FabFilter is known for making unique audio processing plug-ins, ranging from resonating filters to transparent high-end EQ and dynamics processing.
FabFilter Pro-MB is a realistic sounding stereo tape delay with filtering and modulation. You can use an XY, XLFO, an envelope generator or envelope follower to modulate any parameter of either the delay or the filters and it will sync to your DAW.

In this video Jerry runs us through some of the features of Positive Grid Bias Effects and adds some compression with FabFilter Pro-MB Compressor.

FabFilter Pro-MB
Multiband dynamics processing, whether it’s compression, limiting, or expanding, can really help control the elements in your mix. The FabFilter Pro-MB is a multi-use dynamic processor that includes compression, limiting, and expansion as well as gating. FabFilter has not only continued their trend of making complex effects processors easy to navigate (via their help icons and guides), but they’ve gone ahead and made many of the issues that can plague multiband processing obsolete.


  • Up to six processing bands, freely placed anywhere in the spectrum
  • Bands can be easily snapped together to form a traditional crossover system
  • Handles any form of dynamics processing, from highly transparent compression, limiting and expansion to pumping upward compression and punchy gating
  • Unique Dynamic Phase processing mode featuring zero latency, no static phase changes and no pre-ringing artifacts
  • Excellent Linear Phase processing mode, eliminating audible artifacts when quickly changing crossover frequencies
  • Minimum Phase processing mode
  • Up to four times linear-phase oversampling to reduce aliasing
  • Fully customizable per band
  • Steepness of each crossover slope can be freely adjusted between 6 dB/oct and 48 dB/oct
  • Intelligent, highly program- and frequency-dependent attack and release curves adjust depending on presets and compression type
  • Global dry/wet mix from 0% (no wet signal) to 200% (double the wet signal) to easily scale the total effect of the plug-in
  • Beautiful Retina interface with unique interactive multiband display, designed for an optimal workflow
  • Accurate and smooth real-time frequency analyzer with pre- and post-processing options and ‘freeze’ feature
  • High-quality audio processing algorithms with 64-bit internal processing where needed
