Fender BXR 100 Bass Amp

[CJ]

this time it is a Fender solid state bass amp,

sounds pretty good, noisy controls and input jacks,

looks like we are going ti have to operate,

these circuit board pots just don't cut it,

so we are going to hard wire in some big pots,

why pay 9.99 plus shipping for a Fender pot that will break again?

Radio Shack has a good sounding pot with a nice feel for 3.49,
no wait, no ship$$,

barely fits but will last a lot longer,

using 100K instead of 50K, so we make R7 opamp input resistor 10K instead of 4.7 K so we don't blow up, gain is 10, 50K/4.7K = approx 100K/10K
