I personally have a pair of Chandler Limited Little Devil Compressors, and I couldn't be happier with them. I use them on everything, but they're particularly amazing on kick and snare or a drum bus. Big, fat drums are easily achieveable with these. They are also great on vocals and will make a vocal track sound HUGE. Everyone should have a pair of these!!!
These are my main kick and snare compressors! From super smooth to agressive and everywhere in between, these Little Devils are insane! Sonically as amazing as you expect from Chandler gear, and in the convinient 500 series form factor. Everybody needs a pair of Devils!
All I can say is WOW! Full of color! This beast can give you the subtle gentle compression. At the same time, you can compress the hell out of the sound! Mix control is a must have! And the sound, yes, the sound of iron and all analog pathway! It is my favorite on bass and drums, and a bit of electric guitar! A must have piece if you are looking for a colorful character compressor in 500 series format!
I don't own one of these, but I was able to demo one for a couple of weeks in my home studio. So, take my opinion for what it's worth given that limited experience.
I found the Little Devil Compressor to be an extremely colored, vibey compressor, as if adding a bit of pleasant distortion to everything I ran through it (mostly, vocals). As such, I wouldn't necessarily recommend it as an only compressor, but it would add a nice crayon to your box. I found that it did a good job of taking some edge off of a too-bright vocal mic (a common problem I think).
My only complaint would be that the little knobs made it a little tough to dial in the exact amount of compression that I wanted, sometimes. Call me old fashioned, but I like a big bakelite knob to grab with my whole hand...
