NOTE: Once a signal is taken from the SLAVE, it can not be inserted back into the FX Loop Return jack or a feedback loop will occur.
Much like holding a microphone into the PA system's cabinets...a loud high pitched squeal will occur.

Feel free to experiment with the speaker jacks, trying different loads. Keep in mind the greatest clean headroom is always achieved

your nearest Mesa/ Boogie Pro Center.
This i/4" jack allows you control of the REVERB remotely when a cable and Mesa Footswitch are con-
nected. This footswitch is an option and can be ordered by calling us direct or by contacting your nearest
Mesa/Boogie Pro Center.
These two 1/4" jacks are the patch point for external effects. The EFFECTS LOOP is wired in parallel with
the normal signal. Connect the SEND jack to your Effects Input jack. Connect the RETURN jack to the
Output jack of your effect. The EFFECTS LOOP is a patch point between the pre-amp and power section.
Therefore, the RETURN jack can double as a Power Amp Input jack.
This control determines the dry/wet blend of the FX Loop signal in relation to the unaffected
signal. Set to 0% you will experience only the dry signal (no effect) and at a setting of 100%
the entire signal will be wet (total effect.)
For the best results...Set the mix of your effect to 100% wet. Then dial in the amount of
0% 100%
effect that you wish to hear, starting at 0% with the FX LOOP MIX control. The drier (closer
to 0%) signal you use, the better the ANGELS' tone should be. This is one of the advan-
tages in having a parallel type FX LOOP designed into your BLUE ANGEL amplifier...this
This 1/4" jack and control provide a signal derived from the speaker jack. Perfect
for using the BLUE ANGEL as a master pre-amp, or additional power amps may
8 OHM be connected for more power when needed. Some players use this to derive an FX
Send Signal and go to other amps for their wet sound.
16 OHM
Two 8 ohm, two 4 ohm and one 16 ohm speaker jacks are provided. The BLUE ANGEL is not very
sensitive to speaker mismatches and will not be damaged by them, except that very low ohmage
loads will cause the power tubes to wear faster. A single twelve-inch 8 ohm speaker should generally
be connected to the 8 ohm output. When using two 8 ohm speakers, connect them to the 4 ohm
jacks to insure proper impedance matching. Mesa/Boogie 4X12 and 4X10 cabinets come standard
wired to 8 ohms. They have four 8 ohm speakers wired in series-parallel. Some cabinets other than
Mesa/Boogie, may be 4, 8 or 16 ohms; To confirm how your cabinet may be wired and the imped-
