How to Choose the Best Modelling Guitar Combos
Tonal Palette
It's not just about having a lot of amp models; it's about the quality of those models. Does the Plexi actually have that ragged, asymmetrical breakup? Does the clean channel have that glassy chime? Cheap models often lack nuance and dynamic response, sounding flat and lifeless.
Impulse Responses (IRs)
The cabinet simulation is critical. A bad IR can make even a great amp model sound thin and brittle. Look for combos that include a decent selection of IRs, or at least allow you to load your own - a good third-party IR can make a world of difference.
Effects Section
A versatile combo shouldn't just be an amp emulator. Built-in effects (reverb, delay, modulation) can save you from hauling extra pedals, and good ones are surprisingly usable. The key is a flexible effects section; not just presets, but tweakable parameters.
Connectivity & Routing
Modern versatility demands more than just a power amp out. Aux inputs for backing tracks, USB connectivity for recording, balanced outputs for direct to PA - these are the things that make a combo truly gig-ready. Consider how it integrates with your existing setup.
Dynamic Response & Sensitivity
A modelling amp needs to react like a real amp. It should respond to your picking dynamics - a gentle touch producing a clean tone, a hard attack bringing in the grit. Poor dynamic response can make the amp feel unresponsive and lifeless.
Buying Guide
Don't fall for the 'infinite amp sounds' trap. Many combos pack in hundreds of models, but most are just variations on a theme, or poorly emulated. Prioritize a smaller selection of well-voiced models over sheer quantity. Also, pay attention to the speaker - a cheap speaker will always hold back even the best amp modelling. And be prepared to invest in some decent IRs if the included ones leave you wanting.
Our Methodology
We're not just looking at spec sheets here. We've spent weeks playing these amps through a variety of guitars - from overwound humbucker monsters to vintage single-coils - in different rooms and with different backing tracks. We've A/B'd them against real amps where possible, and crucially, we've subjected them to the chaos of band rehearsals and simulated gig scenarios to see how they hold up.
