fx loop - Blue junior

[freedreamer]

Hi to everybody.
I would like to add a Fx loop on my blues jr.. I thougth to copy the buffered version in blues deluxe (see attach) but i have a question.
Considering I want the reverb alwasys on (also when loop is engaged) where would you put the "in" and "out" from buffer ?
the reverb is better to have brfore or after the send/return...?

thanks in advance

Marco

PS i use cream version of blues jr (see attach)
