Valeton GP-5

The Valeton GP-5 is good. There's no denying that. It sounds good - not perfect, but good. The metal housing is sturdy and will easily survive the pedal board, the small size is a plus if you don't want to bring a massive board onto a small stage, and the overall quality of the build is good. But it requires you to use a mobile phone or tablet in order to adjust your sounds. If this could have been done on a computer then I'd give the Valeton GP-5 an almost perfect score. But the need for bluetooth and a mobile device is frankly killing the joy for me. I have an old tablet that I've only used as a map reader on my boat, so I thought it could become a designated GP-5 sound editor. But half of the time the software either doesn't load or doesn't work. So I'll need to use my phone. My studio is already crammed with gadgets, so having to use my phone as well is a bit annoying. But when I get the sound set up then the pedal sounds good. It does have some slight issues in the higher frequencies, but that's only to be expected from a pedal of this price. It doesn't import NAM files directly, but it converts them to its own SnapTone format, which causes a bit of loss especially in the higher frequences. For me this is not a massive issue. I can still get a good sound out of the pedal. I don't use the inbuilt effects, since I have my preferred effects already on my pedal board. The "drum computer" is, in my opinion, totally useless, so I haven't even bothered to try it.
All in all I recommend the Valeton GP-5 for home and live use. I'm not too sure I'd recommend it in a studio setting because of the hight frequency loss.

I got this for on my pedalboard to simulate rarely used pedals for its IR functionality when using headphones at home and for its NAM functionality.
Sadly the overal audio quality of this product, not just NAM or IR but even the build in stuff is just so noticeably low it was even affecting the overal mix when playing with others. No amount of adjusting all my old gear could fix this as the Gp5 was affecting the overal quality. And I don't mean personal preference I'm saying measurable quality. And without a true bypass even turning it off won't save you.
Put of the box it had the latest firmware, Wich constantly made it freeze during setup over Bluetooth, a known issue Wich they recommend a factory reset or a rollback to an older version. Both not being ideal.
Wich is a shame seeing the solid build quality and options.
Maybe it should try to do a bit less but at a useful quality?
I would only recommend this to a new player to fool around with presets to get an idea of what they might like at the cost of some tuner pedals.
Or someone needing a warmup tool pre-gig.
Other than that I can't imagine a useful scenario for the Gp5 and seeing I'm not a beginner or looking for a warmup tool mine has hit the second hand market before I finished typing this review.

In theory this item looks like an ideal backup solution or quick studio toy. The form factor is really appealing - you could definitely use this in a variety of roles.
But one thing I found disappointing is the basic and the most important one: amp sounds. Most overdriven or high gain amps sound similar, and harsh. Addition of overdrive pedal in front of the amp most definitely does not behave as a real world tube screamer (for example) would behave. And the worst flaw of them all: it is not possible to use any high(er) gain sounds without the noise gate, and the noise gate creates awful digital artifacts and does not feel as an amp at all. This is a disqualifying factor for me.

I think YouTube had me expecting too much.

I bought this hoping it would serve as a compact multi-FX on a small pedalboard for a band I gig with, and also as an IR loader for fly gigs or acoustic sets (I’m not a fan of the piezo sound).

The amps and cabs are fine—some of them are actually pretty cool—but overall they feel a bit underwhelming for clean and edge-of-breakup tones.

The reverb, though, is the real disappointment. I just wanted a usable spring setting, but it’s honestly terrible.

There are some interesting distortion options, but overall I’m left feeling underwhelmed.
