do you need to tweak a tape deck???

If you want to tweek it further, get a meter and fine tune the bias for each type and brand of tape you use.

Sugar, in this case I let my ears decide since this deck reproduces whatever recorded at once. Meaning I've already defined for each type and brand(I use) which bias point I need to choose.

My God, I've owned my Nak CR-7 for 12 yrs and all this time it has sat on its stock feet, no tweaks, on the MDF shelf of my Salamander rack. The tapes I make for my car or even--I am loath to confess--to play back during dinner parties on my big rig!!!--sound "just like CDs," for what that's worth. Could I get LP-like sound by putting the deck on cones, points, or pods? It never occurred to me. I felt it was too "low-fi" to tweak. Am I a snob?
