8 tracks on 1/4" tape running at 7 1/2 (I think it was?) w/ pretty nice dbxII noise reduction built in. 7 inch reels only. Dbx defeatable on track 8 for striping synch if desired.
The dbx business keeps you from getting the fullblown, really fat effect of analog tape saturation that you hear with the really big format decks, but the sound quality is there to give you a nice analog feel and at least a good portion of that tape compression when you jam the meters.
Can't put my hands on the noise specs right off hand. But, can give you some subjective comments. If the heads are in good shape, you can get some very nice quality recordings out of this machine. It's a huge old thing and weighs a ton, so keep that in mind if you're paying for shipping, etc.
Best feature, IMHO, is the EQ section on each channel. 3 band, all swept, and very "musical", if you will. Can't be beat if you're just learning your way around the vagaries of EQ'ing a mix--beats the nasty digital EQ I use on
the Roland VS 1680 by a mile, for sure.
Don't know what used 388's are going for, but I'd have to think they'd be a great, inexpensive way to get 8 decent analog tracks at a bargain price. I think the biggest negative has to be lack of phantom power.
Hope this helps?
