Review: This is an absolute basic delay pedal, it does what it’s supposed to do. It works much better when used with the effects loop but good in front of the amp. Not much in the way of settings and options, but it’s a $20 pedal. Buy it as a backup.
Review: This pedal pops so loud when turned on and off that you have to time it out correctly so it becomes a percussive part of the song. That's is if you don't want it to be a pop in the song that's extremely noticeable.

### ⭐⭐⭐⭐⭐ Review
*by J***N on 29 October 2020*

Features I like: - Tone knob is a high pass filter, meaning at full it treble through without boosting, and as you roll it back from full it cuts your treble. Very very useful feature to tame high frequencies of the pedal itself as well as anything you feed it (like a fuzz, say) - Voice knob is a mid-boost with no cut, meaning at off position your mids are not affected, and boosted as your turn knob to full. The "voice" of the mid-freq that gets boosted is very musical, so you can go for no colouration or unique voicing here. More on that next. - With the tone turned up all the way, gain turned down and voice turned down all the way, pedal acts like a pretty transparent boost, except I haven't seen a boost with a high-pass filter as a feature which I think is great. - Sound quality of this pedal is suprisingly good! The breakup of the gain and tone shaping is very musical. No discernable increase to noise floor, pass-through does not colour signal. Parting comment: I haven't played the Vertex Dumble-style pedals that Rhett Shull uses (check him out on YouTube), but to my ear this is a comparable Dumble-style sound at a way way nicer pricepoint with virtually no drawbacks. This is a no brainer purchase - great job iSet. J J
