Reviews about sound are not really needed, just listen to the soundbytes here and on YouTube, the clearest tones will be obvious. The chassis is all-metal with grippy sides, nice ergonomic touch. The knobs are oversize and knurled, another cool handling touch, but the overal shape does not handle as well as the less flattened Boss pedals. Just a detail, we don't manipulate the pedals for long, we put them on the ground and stomp them. The knobs are not too close to one another, you don't turn a knob by accident when touching another knob. All three sounds are very pretty.
The on/off switch makes a little mechanical noise but it's electronically silent, that's what matters. At first I thought the tone knob on a reverb was not needed but I changed my mind. When your guitar has a trebly tone the long repetition of that tone can make it seem like there is too much treble in the echo sound even if there is not too much in the basic sound.
So now I like that feature a lot. The battery compartment is rubberized and tight, it won't jiggle inside. The circuit board is clean with a clear layout, all the soldering points are clean. Steel studs reinforce the pedal close to the switch. The input jacks lock firmly on the Planet Waves, Klotz and Neutrik plugs, same for the 9 volts input.
The paint job is done right without the distasteful and sometimes gory visuals that are the fashion now. I listened to tens of reverbs here and on YouTube, the one offering the best clarity is this one, and by a wide margin, to boot. Plus it's among the least expensive reverbs, so it's a winner's winner, and I recommend it above all others of any price.
