How to choose the best 500 series components
Heritage & Tone
Harrison's heritage is baked into these modules. They're aiming for that characteristic Harrison 'console glue' - a subtle saturation and harmonic richness that makes things sound bigger and more cohesive, particularly in the midrange. It's not a harsh distortion, more like a gentle thickening, which is fantastic for guitars or vocals that need a little extra presence.
Transformer Design
Harrison uses custom-wound transformers in most of their 500 modules. These aren't just for show; they impart a subtle warmth and color, a low-end thump that adds weight and definition. You'll hear it when tracking bass, or when you're trying to make a snare drum cut through a dense mix.
Build Quality
The construction is solid. These feel like they're built to withstand the rigors of gigging and studio use. The pots are smooth, the jacks are robust, and the overall impression is one of quality - a welcome change from some of the flimsy 500 modules out there.
EQ Characteristics
The EQ in Harrison's 500 modules isn't surgical; it's musical. It's got a gentler curve, a less aggressive tone that's perfect for subtle shaping and sweetening. Think of it as a refinement tool, not a scalpel - it's great for adding a little air to vocals or taming harshness in guitars.
Headroom & Dynamics
These modules offer surprisingly good headroom before breakup. You can push them without getting into unpleasant distortion, which is crucial for tracking loud sources like drums or amplifiers. The way they handle transients is also noteworthy; they retain the punch and attack while adding warmth.
Buying guide
Alright, let's talk Harrison Audio 500 series. You're chasing that classic analog console vibe, that warmth and character that's been missing from your digital setup, right? Harrison's 500 series isn't trying to be a clone of anything else; they're bringing that authentic Harrison sound - that slightly rounded, harmonically rich tone - into a compact format. If you're tired of sterile, hyper-accurate recordings, these are worth a serious look.
Look, Harrison 500 modules aren't the cheapest on the market. You're paying for that signature Harrison tone and the build quality that comes with it. Don't expect pinpoint accuracy; they're designed to add character.
If you're after clinical transparency, look elsewhere. But if you're after that vintage console vibe and a little extra sonic mojo, these are a solid investment.

Questions
Are Harrison 500 modules worth the price compared to other brands?
It depends. If you're after a specific 'Harrison' sound, absolutely. If you're just looking for a generic EQ or compressor, there are cheaper options. Consider what you value: heritage, tone, and build quality versus pure functionality.
Do I need a power supply?
Yep, these are 500 series, so they require a compatible 500 rack or power supply. Don't skimp on the power supply either; a bad one can negatively impact the sound and reliability of your modules.
Can I use these modules on a digital audio workstation (DAW)?
Of course! They're analog processors; they work with anything. Use them as inserts during tracking or as mix bus processors to add some warmth and glue to your stereo image.
Are these modules easy to integrate into an existing 500 rack?
They should be. Standard spacing and power requirements. Just make sure your rack can handle the current draw, especially if you're chaining multiple modules.
What's the difference between the different Harrison 500 modules?
Each module has a specific purpose - EQ, compressor, mic preamp. The EQ modules generally have that signature Harrison 'console' tone, while the preamps offer a cleaner, more transparent sound, though still with that characteristic Harrison warmth.
