Rectoverb effects loop hates digital delays. Why?

[Klaasman]

I have a series 2 Rectoverb 50 watt combo. I cannot seem to get my Boss DD-3 or a Digitech digital delay to sound right. There is always some hiss or distortion in the delay part of the sound. I've tried running the masters at all sorts of settings from 8 o'clock up through 12 o'clock. This happens on either channel, clean or distorted. I've tried running the mix knob on the back of the amp from about 30% to 90% and it's always there. I don't have any problems with my Boss Stereo Chorus or a flanger. Just the delay pedals for some reason.
Anyone have some insight on what this noise is? I sure would like to run some delay.
Thanks.

I had the same problem with my Recto-verb head and my Boss DD-20 digital delay. It would never work right and always seemed to get modulation feedback. I eventually sold the Boss and bought an Ibanez AD90(which sounds gorgeous!). Anyway, the analog Ibanez still was prone to the feedback, just not as much. I thought the problem could be the parallel loop. I found the serial loop conversion on this forum and tried that. It was very easy to do if you are comfortable with taking the amp out of the cabinet and doing some light soldering. Now I can run anything in the loop with no problems,
Kinda makes me wish I still had the DD20.

Good luck!

are you running the flanger and/chorus in there as well?
I'm running a DD-3 delay peal in the loop of my Rectoverb head with an MXR 10 band EQ and it's working fine.
I can't run any modulating effects though, I get exactly what you describe, so I just don't bother, I think we need to do the serial mod
in order to run modulating effects wihtout all of the hassles that that this Parallel loop seems to present.
I have a boss ME-50 and I don't even bother trying to use that in the Recto loop, it works great in the loop of my JSX , so there it stays.
In the recto loop all I get is noise.

Well, I tried the series loop mod and it still does it. I'm not talking about the oscillation sound that some people get, (I can reproduce that with the effect level high and mix knob low with delay and chorus)but more of a distorted, hissy kind of sound from the actual echo part from the delay. Not the normal notes but the echoed ones. Savvy?

I have that also. It's only when I'm using the delay on distortion. The delays don't distort until it's at the last few repeats. I'm using a Digitech GSP2101 rackmount.

The only effect I really have a problem with. Haven't figured out how to solve it, so I just embrace it.

hmmmm???? I'm not getting that with my Rectoverb and I'm running a DD-3 in my loop??????????????????????????

Try running the Output volume at higher settings and the channel master at lower settings. That worked for me when my effects started sounding overdriven.

Please tell us your settings starting with the mix knob, effects level knob, channel master knob and output knob. Thanks.

I've had the same problem with my DD20, oscialating feedback.

Maybe I should try my V-amp? :roll:

I have the mix on the level all the way up.
Channel(master) output at 11:00 or below. I think the gain is crisper with the channel volume down , and I run it this way whether there is anything in the loop or not.
I try to keep the out(real master) around 10:00 or up.
I use a hotplate soi can do this at home.
On the delay I keep the effect level at or below 11:00 and it's working fine.
I run it after my MXR 10 band EQ.
so Far so good.

 

[Klaasman]

Hmm, those settings will cause noise for me. I am just going to try and find a delay pedal that can handle a hotter input signal.
Thanks.

HISS

Don't mean to ask the obvious, but have you tried changing your patch cables? Are you using the same ones for your other effects ? Also, you should typically run your delay at the end of your effects chain for best performance. If you are not, it can cause undesirable effects.

OSCILLATING FEEDBACK

This is typically caused when the delay is run in from of a high-gain amplifier. It happens because the delay's repeat/echoed signals are ramped up in the first stage and second stage of the preamp (gain and master outputs) prior to amplification. The higher the gain, the worse the problem.

This is solved by running the delay in the effects loop because wet signal is mixed into signal post-gain. If you still have this problem running in the effects loop, it is because your echo(decay) on your delay is set too high. Back it off and this should fix your problems.
