Oh, earlier in the thread I stated that the number 1 and 2 inputs are
identical on the Deluxe Reverb. I was incorrect.

For each the normal and vibrato channels:

Input 1 when used by itself, presents a load of about 1 megohm. This is
normally what a guitar pickup expects.

Input 2 when used by itself, presents a load of about 136 Kohms. This is
a much lower impedance than most passive pickups expect. The signal will
be attenuated and will have less than normal bandwidth. This low
impedance sometime works better with active electronics in the instrument,
or with some external effects devices.

When inputs 1 and 2 are used at the same time, each presents a normal 1
megohm load. The inputs are isolated from one another by two 68K
resistors.

The Deluxe Reverb has one more inverting stage of gain in the Vibrato
channel. This precludes the use of a jumper to chain the two input
channels together. (The signals will tend to cancel because of the phase
inversion)

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.
