Valeton GP-5 Review – The Mini Multi-FX That Punches Above Its Weight

Every now and then, a pedal comes along that makes you stop and think: how on earth are they doing this at that price? The Valeton GP-5 is one of those pedals. On the surface, it looks like another compact multi-FX box, but spend even a few minutes with it and you quickly realise it’s far more capable than you’d expect. With amp sims, drives, delay, reverb, compressor, EQ, tuner, and even support for Neural Amp Modeler (.nam) files, this little pedal is feature-packed to the brim.

And here’s the kicker: it costs about the same as a Boss DS-1. Yes, you read that right. A full amp and FX rig in a box, for the price of a single distortion pedal.

First Impressions – So Much Packed Inside

The GP-5 isn’t some half-baked toy. It’s a serious piece of kit that covers almost everything you’d need in a *gigging or practice setup. Multiple amp sims, drive pedals, time-based effects, modulation, EQ, compressor, and even a tuner are all packed inside.

What really impressed me is how the amp sims aren't one-dimensional (we all remember the 'amp-sims of 20 years ago). They respond to the guitar’s volume control, cleaning up when you roll back, and they react to dynamics in your playing. That sort of responsiveness is usually reserved for far pricier gear — the kind you’d expect from a Helix or a Quad Cortex, not something that costs a fraction of the price. 

Now, are they at that level of refinement? Of course not. The GP-5 isn’t going to replace a £1500 modelling rig. But in its price bracket, it’s astonishingly good.

*there is a caveat with this, I'll cover later on

Neural Amp Modeler Support

One of the most exciting features is its support for .nam files — Neural Amp Modeler captures. If you’re not familiar, NAM is basically an open-source version of the “amp profiling” technology you see in things like the Kemper, Quad Cortex and even Tonex. It’s still in its infancy, but the fact that the GP-5 can already load these files is a huge deal.

As NAM technology continues to improve, this little pedal could give you access to incredibly detailed and accurate amp tones at basically no extra cost. That future-proofing puts the GP-5 in a very interesting position, and makes it a lot more than just a cheap multi-FX box.

Footswitch Flexibility

The GP-5 only has one footswitch, but don’t let that fool you — it’s surprisingly versatile. It can be set up to bank through presets, which is handy enough, but you can also use it in “stomp mode” to switch individual effects within a patch.

That means you can treat it a bit like an amp with multiple channels: have a clean patch with a boost for solos, or a crunchy rhythm patch where you can kick in extra gain for leads. Alternatively, you can set the footswitch to access tuner mode, so you save an extra spot on your pedalboard and get your versatility from external pedals instead. 

It massively increases the usefulness of the unit and means you don’t feel nearly as limited as you’d expect with a one-switch design. Valeton have really considered the user experience and it shows with the versatility of the switching options.

Editing and App Control

Let’s be honest: editing sounds on tiny multi-FX units can be a nightmare. Menu diving, endless button pressing, cryptic abbreviations — no thanks.

Thankfully, Valeton went the smart route here. The GP-5 can be edited with an app, and it’s wonderfully intuitive. The learning curve is basically non-existent. The amp models don’t use official brand names (for obvious legal reasons), but they’re easy enough to decode, and you’ll quickly find what you’re looking for.

The only downside? There’s no editing without the app. If your phone battery dies at a gig, you’re stuck with whatever presets you’ve already got. That’s not a dealbreaker for practice or home use, but for live players it’s definitely something to keep in mind. There’s also the bigger concern of longevity: if Valeton ever pull the app from stores, the GP-5’s flexibility would take a big hit.

Tone Quality – The Good and the Not-So-Good

The amp models are, quite frankly, far better than they have any right to be at this price. Clean and edge-of-breakup tones in particular are very usable, in some cases getting quite amp-like. Mid-gain options are solid too, though like with any modeller at this level, you sometimes need to EQ carefully to keep them sitting right in a mix or getting them to sound less 'boxy' in certain cases.

High-gain is where things wobble a little. Some of the heavier amp sims feel a bit less refined, and they can sound harsh compared to the cleans and crunch tones. Still usable, but it’s clear not every amp model received the same amount of polish in development.

The drive pedals are unfortunately the weakest link. They’re functional, but they don’t have the same character or refinement as the amps. My advice for this would be: get as much of the tone you can out of the amps themselves, use the drive pedals only as a last resort.

Time-based effects like delay and reverb are solid, though. Nothing earth-shattering, but definitely good enough for live or practice use. Think of the reverbs especially, there are lots of 'safe'  options, but not many wild and outlandish verbs on hand. For those wanting to experience lush soundscapes, this one might not be the best option if you are using it alone. 

Latency – The Digital Elephant in the Room

Like all digital pedals, the GP-5 has some latency. For me, it wasn’t something I could really 'feel' while playing, but some players have noted it’s a touch higher than more expensive modellers. That’s to be expected at this price, but it’s worth pointing out if you’re particularly sensitive to latency.

The Price Point – Game-Changing

Here’s where things get silly: the GP-5 costs about the same as a mid-tier drive pedal. Ten years ago, even the most basic entry-level multi-FX units would have set you back at least £200 or more and it wouldn't necessarily be something you could consider gigging. The fact that this level of functionality is now available at “pocket money” prices is frankly mind-blowing.

Valeton have set a new bar here. Other manufacturers need to take note, because the budget end of the market is starting to nip at the heels of the big players. If the likes of Valeton and Sonicake can offer something with such functionality at this price point, you damn well better be offering something better if you're going to charge more.

Use Cases – Where the GP-5 Shines

So, who is this pedal really for?

Beginners – Perfect for players who want to experiment with different amp types and effects without buying loads of individual gear. It’s an affordable way to learn what tones you like.

Practice – Maybe its strongest role. With headphones and one power cable, you’re up and running instantly. No faffing with amps, pedalboards, or cables. Removing that friction makes it much easier to actually sit down and practice.

Gig Backup – A lifesaver if disaster strikes. Keep one in your gig bag and if your amp blows up mid-set, you’ve got a whole rig ready to plug straight into the PA. *

Travelling musicians – Light, compact, and versatile. Perfect for throwing in a backpack and having a full rig wherever you go.

*You could use it as your gigging amp-sim, but it would be incredibly limited and there are some more viable options in the rough ballpark price-wise

At the end of the day...

The Valeton GP-5 is not trying to be a Helix, a Kemper, or a Quad Cortex. If you judge it against those, of course you’ll find shortcomings. But that misses the point.

What it is, is a shockingly capable, feature-rich multi-FX and amp modeller that costs about the same as a single Boss pedal. It offers a taste of high-end modelling features like NAM support, it makes practice ridiculously easy, and it’s good enough to use as a backup gigging solution.

Yes, the drives are weak, yes, editing requires an app, and yes, some amp models shine brighter than others. But taken as a whole, this is one of the most impressive budget pedals I’ve come across in a long time.

It’s affordable, flexible, and genuinely fun to play. For beginners, it’s a no-brainer. For more experienced players, it’s a useful tool to have around. And for the pedal industry at large? It’s a reminder that the budget end of the market is raising the bar — fast. I bet you're probably asking how it compares to the Sonicake Pocket Master though huh? Well, that is a topic for another time...
