Peavey 5150 effects loop problem

[ShomerShabbos]

I just picked up an old 5150 combo. Sounds great.

One problem: When I plug in a delay pedal (TC Flashback, Boss DD7) into the effects loop I hear instant tone suck.

Do I need a buffer in the loop like the RJM Tone Saver or the Lehle Sunday Driver? http://www.rjmmusic.com/tonesaver.php


Thanks!

I have no experience using the loop on the 5150, but try just plugging a cable in the loop send and return to see if the problem is still there. That will tell you if the problem is the loop or the pedals.

Do you always have both pedals in the loop or do you change them out?

Also, the TC flashback has the option of being setup as true bypass or buffer, and I believe the DD7 is a buffered pedal as well. Not sure on the quality of the buffers, but I would experiment with the TC flashback in buffer and true bypass mode first.

Thanks very much for the help.

The amp is on the band trailer. I'll be able to experiment with it tomorrow night I hope.

I normally run three pedals in the loop: TC Flashback, Hardwire Delay, and Boss DD7. I use these with my Mesa, and they are in good working order.

I'll try setting the Flashback to "buffer". I'm pretty ignorant about the buffer thing. I understand the concept, just not when to apply it. The Mesa doesn't seem to need it, but maybe the Peavey does.

Buffers can be a touchy thing. Some pedals and amps respond to them more than others.

If the order of the pedals in the loop is the same as the order of the 3 listed above, then you have it running like this

FX send > TC Flashback > Hardwire Delay > Boss DD7 > FX return

The TC Flashback is set to true bypass by default, and the hardwire delay is true bypass also. So you have the signal running from 2 true bypass pedals into a buffered pedal (which doubles as a buffer) then back into the amp.

Besides doing the test I mentioned about trying the just the loop in my other post, try the TC flashback in buffered mode so it will have a buffer at the beginning and end of the loop. Another thing to try is swapping the placement of the TC in True bypass mode and the DD7 so there will only be a single buffer in the loop. Usually you dont want any more buffers than necessary, so if just using the DD7 first in the loop gets the job done and you notice the tone improved then I would just do
that.

I hope that all makes sense.
