If halfway decent sound is what you are after, as a previous poster
said in another thread, there is a glut of good-measuring, tolerable
sounding Japanese 70's and 80's and early 90's gear available very
cheaply. People want the vintage tube gear-as with vintage guitars, for
reasons that made a lot of sense years ago but less so now-and except
for a very few pieces old rock era SS mass-fi is nearly worthless. Much
of it works as well as it ever did, which is to say, satisfactorily for
non-critical use. In fact many such pieces are better than the dog****
mass-fi sold in Big Box stores now.
