I have a 1968 Fender Super Reverb (Silverface) Will these pots replace all the old pots in this amp?

We can not verify that all the values of the potentiometers in your amp will be covered by this listing, but as long as the hole size in your chassis is 3/8" these will physically fit.
Product Reviews
Perfect replacement, good quality and value. This saved a Heathkit oscilloscope from the trash heap! Great service. Thank you!!!
I always use the ALPHA pots !! Excellent !! Very precise values , and AES is the best supplier !!
These are my favorite pots for amp builds. They have a nicely damped, positive feel. Bourns pots have a very loose feeling to me and CTS pots are similar to Bourns. It's too bad you can't get these in all the flavors necessary for various builds or repairs.
Great pot. Smooth operation.
Excellent linear pot. Smooth operation.
Nice solid unit - smooth action
These seem to have tighter tolerances than CTS pots, and I like the firmer rotation feel.
I bought these for the Bass and Treble controls in the tube pre amp that I built.
They work fine.
The pot is decent quality. no problems
Nice inexpensive pot
