The Lunar echo is really cool sounding, if you can afford one it would be a great toy to keep on deck..BUT I gotta tell you that is NOT
how a tape "Echoes" or repeats the initial note.. Rather what you are hearing in the Lunar Echo's slap back is a very tailored sound of some
odd characteristics of both bucket brigade chips and low resolution digital chips.
If you want to be daring with your analog delay pedals, you can adjust them to have the psuedo ring modulation smear, that youre hearing from the Lunar. I dont recommend doing it with a good analog delay unless you have an oscilliscope to recallibrate the OEM clock settings.
All to say that in your analog delay pedal there is a delay chip that
is capable of a static length of storing a signal and then repeating
it(actually voltage but lets stick to the layman terms).
The BBD(bucket bridge analog chip) has to be "dialed" in for best intelligability for its "slap back" or repeat.
So... if you change that clock setting by turning the little trim pot
inside the pedal that is meant for its clock, you cause the chip to now
shorten its storage or maximize its storage of the signal.
If you max the clock, your delay slap back time will increase
BUT the quality of the slapback goes to hell and the sonic result
of the slapback is a ringing tone. Ala RING MODULATION..
very cool but only for "lunar" effects..
Like I said once you manually screw with an analog pedal's clock OEM setting, its near impossible to manually return it to the initial setting unless you have an oscilliscope and in some cases the chip just gets F'kd up. So.. find yourself a cheapo 80s DOD
analog delay (the light blue one) and you can play with the clock settings at will... if you need to like I do.
ALSO.. with early digital delay effects, the sample rate of the digi chip was not what we have today and it too was limited to how long
one could have a slap back time. So when you would max your delay time, the integrity of the original note would become almost grainy
and while it wasnt a clear and articulate "echo" of the original note, it resulted in a very nice creamy sort of slap back especially for space rock (think Floyd). ...but it didnt sound like a tape echo's smooth tape smear and saturation with the slight wow and flutter.
(btw.. high end analog tape player/recorders had very little
wow and flutter as this is undesirable in recordings..the aging of
pinch rollers and drive motors are why we like the modulation effect
of tape echoes though)
So... if you have an early digital delay pedal or rack effectbox, you can mess with the internal clock again and get those super grainy, highly NOT articulate slap back sounds too
BUT if you own a line 6 DL4 delay pedal, its actually one of the stock
settings called "low Res".. its awesome for exactly what some of that lunar echo is doing.
btw.. the new EH deluxe memory man is in a nice little compact hammond box and kicks ass.
