Positive Grid Spark 2
$21 under the $300 cap
Guitar World ranks it beside the Katana and the Yamaha THR — 33 amp models, an AI tone generator and a jam-track looper for practising on your own.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Those are 4-inch speakers, not a guitar speaker. Spark 2 is a bedroom learning platform, not a band amp — dual 4-inch FRFR drivers give hi-fi practice tone, and the card sends gigging players to a 12-inch combo instead.
Dealbreaker? Runner-up №1, the 12-inch Mustang LT50, costs $29 less ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you need a professional gigging amp for large venues
- you want a bass guitar amp
- you only want a tube amp above 5 watts and will not consider solid-state
- you want a desktop-only practice amp under $200
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Positive Grid Spark 2 is right for you
It avoids every trap below — and for just me, no budget cap, it is the pick because it delivers:
The cap moved, the lists didn't
The best modelers have priced themselves out of this bracket — the Boss Katana-50 Gen 3 is now $339.99 on Amazon, the Blackstar Debut 50R $329.99 and the Yamaha THR10II $369.99. Follow last year's under-$300 list and you blow the budget.
Watts are not volume
A 50W amp is only marginally louder than a 25W amp — what the extra watts actually buy is clean headroom before the tone breaks up. Do not pay for volume you can never use in a flat.
Dead listings everywhere
Three amps that anchored this bracket are discontinued and now read Currently unavailable on Amazon — Boss Katana-50 MkII, Marshall Origin 5W and Line 6 Catalyst 60. The Catalyst's replacement, the CX 60, lists at $329.99, outside the cap.
