Simple to use and better results than the sub $75.00 low voltage stand alones.
Good sound quality. Does not color the sound unless you add gain. Slightly overdriving a top snare mic or vocal really brings details out and adds a harmonic quality like a good old fender guitar amp does for guitars.
Great value for price. I've had this for over 10 years and paid retail. Find one used for a lot cheaper. I've used it in live FOH mixing, tracking, mastering, between pods/sans amps and DAWs. Very rugged and reliable. Would buy another to add more tube front end to my DAW. I like scooping the 2 bands of sweepable mids on vocals and kick drums. Replaced the stock tubes with EI 12ax7.
