this is the third tape deck ive bought and the only one that gives any good quality bass/treble adjustment

That's a lot of bass

@PonySlaystation it's not that much bass when you actually listen to it, maybe my headphones or tape deck isnt getting the bass right. then again, it's about what any song looks like under a spectogram. more talking about the distortion (some stupidly complicated pattern that i cant just use a sine wave function to fix).
