Mr Paul Tapsell6th Feb 2024

The product is great, but the manual lacks any examples of how to set up patches stomp functions on the footswitches. This is the first time I've ever used a multi-effects: the manual seems to expect that you are already an expert. It would be great if Anderton's did a real-life 'how to use' video, rather than the usual review videos.

This is at the budget end, but it is packed with good stuff, and sounds great to me. I have resisted "digital" for ages, even though that is a dumb stance since pretty much all that I create ends up digital, but you know, a guy has to try! My first dive in to modelling and I love the possibilities. I did look at the new Boss pedal since it seemed pretty cool, but the price was 3 or 4 times this, and at my stage of playing that was not a good investment. I have not even started to really learn what can be done with the GP-200. There has been online criticism that you can, for example, only have 1 distortion in a chain. This is true, though there are overdrives in the Pre slot, plus you can make your amp overdriven if you want, so that is 3 stages of drive. And to be honest, I need less options, not more, so I don't get "analysis paralysis". The only thing I have found that is negative is the shimmer reverb. Even with heavy EQing it sounds to me a bit nasty digital, nothing like my really rather good Oceans 11 pedal, so that one pedal is likely to stay with me, and perhaps the Polytune tuner because it is really accurate for single notes and quick during gigs with all notes. Otherwise, nothing to fault this device, I would strongly recommend it. Oh, and it was for me, like plenty of others, the Anderton's YouTube episode on this that finally persuaded me!
