    So iam sitting here with my new rig...OrangeRV50 various pedals..VS jecklw and hyde, volume pedal and a sex drive booster.. I want to add a delay and some say it should be added to the fx loop but my sound is cut and i cant really hear it?..input on the delay goes to send out put to return...right? so why is this not working?

    What kind of delay it it? Is it a line level device?

    I have the same problem running my delay in the efx loop of my Rivera

    The rivera has send/return/mix control but I still can't get enough volume with my SIB echodrive. Your Orange doesn't have any controls so I'm sure you're having "unity gain" issues

    I solved the problem by putting a zvex super hardon clean boost after the delay in the efx loop. It gets a little too loud... so then I dial out a little volume with the level control on my delay

    The SHO has another benefit... it kind of supercharges all your efx... gives modulation efx huge lush sweeps

    Assuming that the Delayla and the loop are both functioning properly in and of themselves, the problem might be that the loop is a line-level design, but the Delayla is an instrument-level pedal. That would cause the pedal to get overloaded at its input and then not deliver enough signal back to the return of the amp, resulting in a weakened, crappy signal.

    I'm not familiar with the Orange's loop though, so this could be off base.

    someone needs to invent a device that will turn line-level into instrument level.

    Does anyone do this, and is it even possible?

    Vox made one in the early 90s. It was called the Valve Effects Loop Buffer. It uses a 12AX7 tube and it does the job wonderfully. I remember one set up with a demo Marshall amp at the 1994 Summer NAMM show, but Vox discontinued them the following year. In 2001, I discovered I had a need for one. I did some Internet searches and found a used one, and it's working for me in my rack with some Ibanez Power Series pedals.

    It's the Vox unit right above my nameplate:

    Amp loops can be a challenge, if you turn the amp up really loud, it will probably provide a hot enough signal in. If you have a master volume, it will probably have to be up high as well. If your last effect in the chain has a variable out, that will be your new master volume. Regardless, any power tube and speaker distortion will distort the effects anyway.

    Some go with wet/dry setups, but that gets pretty complex. Some keep their effects before the amp and maybe get a lot of their distortion from a distortion pedal placed before the other time based pedals ... but then you've defeated the purpose of buying an amp with great tone.

    Just to double check (I had a little difficulty understanding exactly what the original poster meant..could just be me) You ARE getting some sound, just not enough?

    If you are getting NO sound, you have it backwards.
    It should go AMP-SEND->Delay input----Delay output--->AMP-RETURN.

    If that is not the problem, just the levels, you have the opposite problem from me. I bought a Fender Prosonic, and it was designed to use LINE LEVEL in the FX Loop. (+10db).

    This was WAYYY too hot for my poor little digital delay (H2O pedal), but my analog stuff handled it fine. In my delay though, it hit the ceiling making terrible noises when I hit it hard.

    I got a "-6db" cable that drops the signal level, but then lost too much volume, and if I tried to make it up by raising the volume, back to the same problem!

    Someone here pointed me to a "Nobels SPX-31".
    Check Nobels site, and you can maybe find it. I bought mine from a german firm. I asked them though and even though they claim +10db is handled, they emailed that it was too high. I decided to try anyway. I haven't gotten a chance to use it yet (my amp is at rehearsal place and I haven't gotten there this week), but it has an input that can be regulated down, two seperate sends that ALSO have knobs for adjusting the levels, and at the end you can mix the loops with the original signal AND bring up the level again.

    It's an amazing concept in the little tiny box. They say it runs better at 15Vdc. Again, it might color the sound (you are reamplifying using this kind of thing) but I am going to give mine a try.

    :eek: +10?!?! That's *really* hot, I think. Even most line-level pro unit stuff is only +4 dB.

    Instrument level stuff is typically -10 dB, afaik.
