The Tele knobs are great! Callaham make great stuff....
Sold my Callaham bridge and got a Glendale, for more twang. Got stainless steel saddles but then replaced the D/G and B/E for Wilkinson Brass ones as I had too much twang! Now it's just right.
The callaham gives a fuller, fatter tone, it's not night and day difference but it's noticeable.
I like them both. Fender ones are good too though...
