Yuer Analog Delay promises you a very simple vintage-style analog delay and it surely delivers.
This is not a digital delay, so don't expect it to do things digital delays do. Analog delay is different. But anything you can expect from a basic analog delay, you can get from this. Slapback for rockabilly, a little bit of extra space to smooth out solos and rhythmic patterns that don't go on for too long, you can get all of those from this pedal. Being an analog delay, you can also get crazy synth-like self-oscillation by turning up the repeats and then playing around with the time and mix knobs.
Build quality seems decent, thus far I haven't noticed any faults in the knobs, switch, jacks or casing. It's nicely small in size, fits easily on a pedalboard.
I bought this mainly because I'm very new to delays, so I just wanted something to try out without spending a lot of money. If you know you want a Strymon with a ton of knobs and options, you probably don't want this, but if you just want to have a simple delay, you can't go wrong with this.
