Where can I start with such a wonderful piece of software... Let's keep it simple.
Sound: Overall EchoBoy sounds very good. I wouldn't say it sounds real analog, but not cold harsh or digital at all. Just very good. Huge variety of sounds are possible thanks to the 31 (!!) different delay/chorus styles (from known types like Tape, Space Echo, Memory Man, DM-2, CE-1, etc.). Then you can drive those styles very nicely with the input. There are also new unique styles like Telephone, AM Radio or reverbish styles and so on that give you instant access to cool new sounds you normally don't expect from a delay. Still not satisfied? Go deeper into the style edit mode and create your own styles and save them.
Delay: You can expect the usual, but no extraordinary long delays. In most cases it is way enough. But if you need delays longer than 1 bar, you'll need to look for another contender. EchoBoy gives you two parameters for direct groove access: Groove and Feel. Generate fast and easy funky groove patterns. Besides the style you can dial in extra LPF and HPF. And switch between different delay modes (Single Echo, Dual Echo, Ping Pong and Rhythm Echo. Rhythm Echo is a very complex mode, where you can tap or paint your delays (and save them next to the already existing Rhythm Echo patterns). The other delay modes also gives you further in depth parameters like width, accent, offset and more.
There is much more. I just recommend you to get the demo. I promise you will buy EchoBoy afterwards. I use it all the time in every project multiple times.
I got the demo and this is pretty nice. The hidden controls to tweak and edit the style are very powerful. Its a bit expensive though. I'll see if I can find other plugins in this ballpark that are not as pricey, within the 30 day trial period. If not, I think I'll pick it up.
