I am wiring up my rig differently and am looking to patch my volume pedal between the effect send and return. I suspect it is line level but just want to be sure... davehouck Moderator Username: davehouck Post Number: 5286 Registered: 5-2002 Posted on Thursday, July 12, 2007 - 12:47 pm:    This is from the Alembic F-1X web page: Two input jacks provide the same functionality as found on the F-2B preamplifier. The input is buffered by a cathode follower tube circuit, which is a unity-gain impedance matching amplifier to feed the guitar level effects loop. This gives minimum loading on the output signal from the guitar while driving the effects loop gear with the same signal voltage level as the guitar but at a lower impedance, to isolate cable and other loading effects from the guitar pickups. 0vid Member Username: 0vid Post Number: 88 Registered: 4-2003 Posted on Friday, July 13, 2007 - 9:42 am:    thanks Dave peter_jonas Member Username: peter_jonas Post Number: 51 Registered: 11-2002 Posted on Saturday, July 14, 2007 - 8:04 am:    Output impedance of Effects Send is in the order of about 1.0 kilo ohms, input impedance of Effects Return is 1.0 Mega ohms.
