## Customer Reviews

### ⭐⭐⭐⭐ Very impressive. Woefully poor instructions let it down
*by F***R on 19 May 2025*

First of all this multi-FX processor exudes quality. It is superbly made from quality metals and switchgear. The steel casing is sturdy and the graphics well finished. Had it carried 'Roland' as the maker's name I would not have been surprised. Even the packaging is decent quality!The circuitry is quiet enough for direct recording and listening through headphones. Only some of the effects buzz and hiss, and I suggest this is because they are intended to sound like that!However, the user interface is not intuitive and needs to be studied carefully before it all makes sense. Unlike competing products from people like Boss you will find it hard to play straight out of the box. You will not be playing wah lead on Cream's 'White Room' until you work out how to assign the wah function to the expression pedal. The instruction booklet is a huge disappointment as it is a poor translation to English and comprises a list of features and component identification charts with very little help to the user who wants to learn how to use the device and does not have a week available to do the necessary research. Even some of the displays are badly translated. The manufacturer's website is little help, and the only online reviews I have managed to find simply list its capabilities - in exactly the same way as the Amazon listing.The device has an awesome specification for the price. You should research exactly what it can do. I expect you will find there are not many competing devices which include multi-Fx, a looper, expression pedal, amp simulation patches and a drum machine in the same exquisitely fashioned box.I really like this device and look forward to working out how to use it in the coming months, but until then my current stage setup will not change!
