New Einstein loop questions

[moltenmetalburn]

I have recently acquired my first Diezel. I have the Einstein and am absolutely loving it! I have some questions about the effects loops. I have only owned amps with series effects loops in the past, I use an Isp decimator in the loop to silence ALL hiss from the preamp section and any noise inducing pedals in front of the amp.

With the Einstein i plugged my decimator in the series loop and my delay pedal in the parallel loop. the decimator does a fine job of making the amp dead silent when used in the series loop alone, BUT when I also use the parallel effects loop there is some hiss added that I cant control with the decimator.

Is the parallel loop AFTER the series loop in the signal chain?

will i require TWO decimators in order to have dead silence while using both loops?

(hmmm maybe its time for a rackmount effects processor with a noise gate! G major?)

I realize the amp is by no means noisy even at extremely high volumes but I have always been a stickler for absolute silence when not playing.

thanks!

How are you running the delay pedal - I'm not 100% on the diezel loop even though I have an einstien and should be... but with my Randall your supposed to run the pedal mixed to full wet and then mix in the sound accordingly with the knob on the amp to prevent phasing problems.

If your already running your delay pedal like this then you got me... if not maybe it will help?

As I understand it the parallel loop isn't parallel with the serial but with the preamp section of the amp, so part of the signal goes to the loop and effects units, the other part goes unchnaged into the preamp section. This means that when running digital effects you don't lose tone in the ADA conversion.

The reson you are getting hiss is becuase the preamp is still running an uninterupted signal in parallel mode.

At least that's how I understand it.

I am running the delay unit correctly to avoid phasing issues. All parallel loops should be run this way. thanks for the effort.

You are correct. I understand all of this also, my real question is about the routing of the signal through the loops. as far as i can tell the serial loop must be before the parallel loop. If the serial loop were after the parallel the decimator would be able to clamp down on all hiss. Im sure the design philosophy was to allow delay repeats to trail uninterrupted by gates and suppressors.

I guess ive answered my own questions but Id like some moderator confirmation I suppose.

Ive realized the new G-major 2 will suit my needs perfectly and then some so Ill probably start saving up for that one. It really seems ideally suited for the Einstein. it will switch amp channels, has individual patch level settings for those of you with modded Einsteins, (youll be able to have consistent volumes through the channel 1 modes) and has a noise gate.

Why are you getting a "hiss" from the amp? I have run digital time based effects in my Einstein in both a series and parallel loop, and never have one hint of noise?

good question. the amp is silent until you plug the loop in. the hiss is present even when inserting a patch cable into the parallel loop. maybe i need to experiment with he tube driving the loop? anyone know which one that is?
