When I'm not flouncing around trying to play blurry guitarnoiserock from 1991, I like to play weak chord sequences and to pretend I'm Johnny Marr. For some time I played through a lovely JC-120. Ignore the hiss, love the chorus, and embrace solid state, people. It was a cracking pedal platform and not as heavy as you'd think (at least the 3rd series weren't. I did have a 1st series temporarily that had been butchered by the previous owner. He'd thrown two Celestion speakers from the 70's in there that had magnets built like the average Samoan prop forward. The whole amp weighed nearly 50 kilos).
So jingle-jangle Marrology picking... what compressor? For ages, the Diamond compressor has been my favourite. Stuff like the Keeley 4-knobber and all of the usual names squash the top end and you lose that sparkle. The Diamond dials it back in with the Tilt EQ. It still sounds nice and open, it's not a big squashed compressed sound, but it adds thickness in the right areas.
I bought the Mooer Yellow to see if the claims were true.
In short, I disagree.
For £30 the Moeer Yellow offers you a lot for your money. The first thing that hit me was just how small it was. I've had bigger buttplugs than the box this came in. When hooked up to the DAW, it's quiet enough, definitely not unreasonable in the noise floor department. It definitely isn't as nice sounding as the Diamond. Ovni Labs reviewed the Diamond and the Mooer Yellow, and I'd agree with everything said there. The Diamond has a fullness that the Moeer simply doesn't have. In my pedal test, I ran the Moeer on its own then compared that to playing directly into my favourite software compressor, Klanghelm's MJUC. I preferred going into the software compressor which is not something I ever said when I had the Diamond.
That said, the Moeer going into MJUC is rather good.
Is this worth £30? Yes. At that price it is a ridiculous bargain. Does it beat the Diamond compressor? No.
