I needed something for home practice in headphones with the ability to play bluetooth backing tracks, and also with stereo in+out for continuing to the PA. There was also the KMA Endgame in the game, which I wanted more, unfortunately I needed something that could be at the very end of the chain, since I have tremolo and reverb pedals after the Tonex and UAFX Knuckles and I think that the doubler in the Endgame should be right after the drive section, not after the modulations. The pedal is basically a small headphone amp with a handy headphone out mix, a big plus is the ability to connect a Bluetooth device to play backing tracks. The metronome is set up quickly and easily, it works well with a guitar in headphones, the tap tempo button is also nice, and it flashes according to the metronome speed, but what I don't like is the metronome sounds, they could add some wooden click or something more pleasant to the update, or give the option to record your own sound. Someone complained in the reviews that the bluetooth and metronome can only be heard in headphones and do not go further to the unbalanced 1/4 outs. This is not true, with a few clicks you can set whether only the guitar goes to the unbalanced out, or the guitar with an aux/bluetooth backing track or with the metronome as well. People also complained about the bad sound in headphones, the headphone out with an impedance of 16 Ohm works perfectly with my AKG K371 which are 32 Ohm, great sound. In the third firmware update, some functionality was fixed with headphones, but it was fine for me before. The pedal is absolutely fine, but unfortunately the price is absolutely overpriced. The pedal is high quality, easy to use, you can't go wrong and I understand that Walrus, as a prestigious brand, can't suddenly afford to release a cheap pedal, but I think that €150 would be appropriate, considering that it's not a unique drive or unexpected reverb, it's just a metronome with Bluetooth aux and a headphone amp. I've had the pedal for some time and despite the high price I'm satisfied.
