Gus,

According to the block diagram in the manual, you're absolutely 
right. I still wanted to see for myself exactly how long the delay 
was though, just out of curiosity.

When I first did the test I recorded the signals direct to computer 
without cabinet emulation. I just wanted to measure the delay so I 
used the clean tube setting with very low distortion and hit a short 
note, so I wasn't concerned with sound quality. I normally play 
through a power amp and speakers, and mic that when I want to record. 
But I did go back today and recorded a small sample after placing the 
global EQ flat to compare Effects Send with the main output at 100% 
dry. Though the slightly different playing in the two licks makes it 
harder to judge, I don't hear much difference in sound quality. It 
was played through an ADA MicroFet poweramp and speakers and recorded 
with an SM57. The first lick is through the Effects Send and the 
second is through the 1/4" Right Main output. Here's an mp3 of the 
clip so you can judge for yourself:
