OP, of the two amps mentioned it go with the ‘68 Custom Deluxe Reverb with the NEO Creamback speaker. I’ve played this factory upgraded amp and it sounded spectacular. I would first look into finding a vintage SF Deluxe Reverb or SF Vibrolux Reverb for around $1000. Plan on putting another $200-$250 in the amp to have it serviced. You’ll then have an amp that could possibly last a lifetime and will appreciate in value.
