tell a component’s true advantages until it is used inthe right context.A
guitar that has very piercing highs could theoretically be tamed down
somewhatby using a long guitar cord that offers some high-end
attenuation.The loops of your Einstein send signals at higher levels and
impedances, whichmakes this section of wiring less sensitive. You
should still use reliable and goodquality wiring for all loops.

3.2.1 Send/Return Loop
The system consists of 2 separate Loops. It allows creation of effects
path ineither serial or parallel configurations. The individual channel
volume controlsdetermine the signal strength at the send jacks. The
range is ... to +10dB. Theoutput impedance is 4.7 kΩ. To use the
Send/Return Loops, connect the “Send” tothe “return” or “input” or
“in” of the effects unit. Be sure to adjust the input levelof the effects
unit to the amplifiers level. Most effects units have led bar or
otherlevel control devices. The Output of the effects unit must be
connected to one ofthe return jacks, parallel,, or serial. If you use the
parallel return, then the signalcan be mixed to the original signal via
the rear panel mounted “Volume” control.
3.2.2 Parallel or Serial
Which is better for you? Read on.There are 2 ways to handle effects
signals. The serial loop interrupts the signalpath of the Einstein and
the signal is sent to the processor, becomes processed,then sent back
to the serial return into the power amp. Digital effects units
oftendigitize this signal once received, then process the signal, convert
it back toanalog, then send it to the amp. This is called ADA (analog
digital analog)conversion. It is necessary for digital effects units
digitize your guitar signal sothat the processor can read and
understand signal. Your tubes, however, need ananalog signal to
operate, so the processor converts the signal back to analogbefore it
goes back to the amp. Generally, even in highest quality
effectsprocessors, this causes a change in the original signal, typically
a loss of tonalityand warmth, also noticeable as a “harder” sound.
When you use the serial loop foran effects unit like this, then your
signal will have been ADA converted at leastonce. Tone junkies and
vintage freaks alike will more than likely have hivesdeveloping by now.
But - as always, there is a better way. Use the Parallel loopand the
