Delay pedal kills my volume

Submitted by anonymous on Mon, 03/15/2010 - 11:15

Gear in question:
Peavy Valve King 112 tube amp
Boss DD20 Giga Delay

Issue:
I just bought a Boss DD20 Giga Delay, and when I set it up the output is barely audible. It's pretty simple to connect, so I don't think anything is wrong there (amp send -> pedal mono in, pedal mono out -> amp receive). I also noticed that when I unplug the pedal and only plug a cable into the amp's Send jack, the volume goes way down even with nothing connected, so maybe it's not the pedal at all that's the issue.

Any idea what's wrong?

Ok, turns out I have no idea what I'm talking about when it comes to amps and amp effects. So after a little research, I think I have a better idea of what's going on (but not how to fix it).

In my first post, I was trying to hook up the delay pedal in the effects loop (after the preamp and before the power amp, right?). I tried hooking it up before the preamp, and it works and is at full volume. But I read that, generally speaking, people put delays in the effects loop. Why is my effect loop volume so low (I don't think I have a volume knob specifically for it like some apparently do)?

Not sure if its the effects loop that is really low or the fact the Giga delay isn't putting out a line level output, but a guitar level output. I'd guess your send is expecting a line level return from rack-type gear, but the Gigadelay is sending a guitar-level signal. Without looking at the manuals for the amp. Either that or your amps effects loop has something wrong with it. Either way you should be fine the way you are now.

It looks to me like the insert is setup for guitar pedals. From the manual:

EFFECTS SEND
1/4” output jack for supplying signals to external low-level effects or signal processing equipment.
EFFECTS RETURN
1/4” input for returning signals from external low-level effects or signal processing equipment. This is a
switching jack. Inserting a plug into this jack will break the signal path until it is returned via the
EFFECTS SEND (#13) jack.

Effects Send:
Low Impedance: High-Z, 22 kΩ
or greater
Nominal Output Level: 0 dBV,
1.0 V(rms)
Effects Return:
Impedance: Very High-Z, 1 MΩ
Designed Input Level: 0 dBV,
1.0 V(rms)

TBBucs, try running the guitar into the pedal and that into the return.
