Positive Grid: A Complete Buyer's Guide
Spark 2 or Spark MINI? Do you need BIAS software as well? Here's exactly what to check before buying Positive Grid gear.
Right, let's cut through the marketing and get you buying the right Positive Grid gear the first time. There's a Spark for the desk, software for the laptop, and a genuine difference between the models that isn't always obvious from the product page. Here's everything worth checking before you spend a penny.
Work Out What You're Actually Buying For
Before you even look at spec sheets, be honest about what you need this for. Quiet practice in a flat? Recording demos? Teaching lessons? Jamming with a Bluetooth backing track before bed? Positive Grid's whole range is built around practice, home recording and informal playing rather than gigging, so if you need a stage amp, look elsewhere first — this is a different job.
Spark 2 vs Spark MINI: The Real Differences
These two get lumped together constantly, so here's the comparison that actually matters when you're deciding.
| Spec | Spark 2 | Spark MINI |
|---|---|---|
| Power | 50 watts, two angled speakers | Lower power, single compact cabinet |
| Best for | Home rigs, recording, small rooms | Travel, tight spaces, grab-and-go practice |
| Looper | Yes, up to 60 seconds, Simple and Groove modes | Simplified feature set |
| Connectivity | Bluetooth, Wi-Fi updates, USB audio interface | Bluetooth streaming |
If you've got the desk space and want the full feature set, the Spark 2 earns its higher price. If you're genuinely tight on room, or this is going in a backpack, the MINI does the essentials without the extras you'd never use anyway.
Amp Modelling and Effects: What to Actually Check
Every listing shouts about "33 amp models and 43 effects", and yes, that's the Spark 2's count — but the number alone tells you nothing. What matters is:
- Preset structure — you get one amp model plus up to three effects before it and three after, so check that covers your usual chain (drive, modulation, delay, reverb).
- Amp variety — look for a spread across clean, British crunch, American high-gain and modern metal voicings, not just one flavour repeated.
- Full-range speakers — Spark uses full-range drivers rather than a single guitar speaker, which is brilliant for versatility (bass, acoustic, backing tracks) but feels different from a traditional cab if you're used to one. Worth an in-person listen if you can manage it.
Connectivity and App Features That Actually Get Used
The app is not an optional extra with this brand — it's most of the product. Before buying, confirm your phone or tablet is genuinely compatible and up to date, because features are tied to app versions. Two features worth knowing about going in: Smart Jam, which builds a backing track from whatever you play, and Auto Chords, which reads a song and shows you the chords. Both are proper practice tools rather than gimmicks, and Spark 2 additionally adds Spark AI, an assisted tone-shaping feature — treat its suggestions as a starting point, not gospel, and always finish by ear.
Do You Need the BIAS Software Too?
Here's where buyers often overspend. BIAS FX 2, BIAS AMP and BIAS PEDAL are separate software products for computer or mobile use, aimed at building deeper virtual rigs than a hardware Spark alone offers. If you're mainly practising and jamming, a Spark amp on its own covers you completely. If you're serious about home recording and want granular control over your signal chain, BIAS FX 2 is worth adding later — it's not something you need to buy on day one.
Checking Stock, Warranty and Firmware Before You Buy
A couple of practical checks save headaches after the parcel arrives. Positive Grid ships feature updates as Wi-Fi firmware, so ask the retailer whether the unit on the shelf is running current firmware, or be ready to update it yourself the moment you switch it on. Register the amp with Positive Grid directly once it lands — that's what gets you warranty support and any future software perks tied to the account rather than the box. It's also worth comparing bundles across sellers, since the battery pack and foot controller are often sold separately rather than included, and a "complete" bundle from one retailer can be considerably better value than buying each piece separately later.
Mistakes to Avoid When Buying
- Buying on amp-and-effect counts alone without checking preset structure suits your actual sound.
- Assuming full-range speakers will feel exactly like your old guitar combo — they don't, and that's not a fault.
- Skipping the optional battery pack, then being annoyed there's no built-in one — Spark 2's roughly eight hours of untethered use comes from that add-on, not the amp itself.
- Buying BIAS software before you've worked out whether the hardware alone already does the job.
My Verdict
For most home players shopping the Positive Grid range, the Spark 2 is the one to buy — it's the most complete package and the one the whole ecosystem is really built around. Go smaller with the MINI only if space or portability genuinely rules the Spark 2 out. And hold off on BIAS software until you know you've outgrown what the hardware alone gives you. If you want the fuller picture of how the whole range fits together, our Positive Grid explainer lays it all out, and our best value picks narrows it down further. Brand new to modelling amps generally? Start with our beginner's guide instead.
Bottom Line
Buy the Spark 2 if you've got the room and want everything the platform offers; buy the MINI if portability wins; add BIAS software only once you know you need it. Get that decision right and you'll be reaching for this amp for years, not shelving it after a fortnight.
