Peavey Session/LTD preamp pedal question

[Larry Dering]

I noticed that my Session LTD preamp pedal doesn't pass any signal unless its in the on position. Surely that's not the way it's designed to work. The owners manual was no help. Anyone else run into this?

[Dennis Detweiler]

Hmmm, mine just bypasses the preamp. I still get guitar signal to the amp.

Me too Dennis ... Larry how are you hooked up?

[Larry Dering]

I have steel to black box, then volume pedal, Session LTD pedal, reverb pedal then Tonex Cabinet. I'm going to try switching reverb pedal in front of LTD pedal instead of after it but I don't see why that would matter. I'm using the Donner power supply and while it's better than the Dunlop there is still white noise with any serious volume.
I will also test it with no reverb pedal involved. Pretty sure I did that already. I will post the results when I get back to my steel.

My sequence is: guitar-matchbox-volume pedal-pedersen strobostomp-delay-reverb-session 400 pedal-quilter201. It's quiet.
The 400 pedal volume 7 and sensitivity 10

Well today I tested with no reverb in the chain and it passes signal when off like it should. I put the reverb pedal in front of the LTD pedal and again it works correctly. I didn't try swapping back with the reverb after it.
I had the sensitivity maxed and volume on 4. I didn't notice the white noise in this configuration. Thanks for all the responses. I didn't get to play around much today. I had it going into a PA channel.

[Dennis Detweiler]

I can't imagine why the position of the reverb or any other effects pedal would effect the on/off of the Session Pedal? Maybe an electronics tech will reply. I'm just curious.

[Larry Dering]

It's very odd but I have read about digital and analog pedals not playing well together. I don't understand it either.

[Dennis Detweiler]

I read that also. The 400 pedal is analog. The chain sequence must be a factor between digital and analog. I use an Ibanez mini analog delay and a Nux Damp mini reverb (digital). All in sequence in front of the 400 pedal. I've had no problems with signal and quietness. I must have accidentally got it right. I thought about trying those pedals after the 400 pedal (the equivalence of an effects loop), but not going to rock the boat. I always thought the Sensitivity knob on the traditional Session 400 was the same as a Master volume control. I later found out it is not. It is actually an output control on the Preamp. So, the power amp section of the Session 400 combo amp is always full on. Turn down the Sensitivity for a more quiet amp for session work. Peavey ahead of its time.

Ah, the infamous double post.

[Roger Crawford]

From what I’ve read, effects pedals should always be in front of the Session pedal.

Well for whatever reason I put the reverb after the Session pedal and low and behold today it passed signal like nothing was ever wrong. I'm scratching my head about this. However I am running into the PA and when it wasn't working I had the output going into the return of a Fender Mustang III. Maybe the Mustang was the issue? I will have to test that theory later. The Mustang takes other pedals in the return with no issues. I appear to be losing my grip here and have to redeem myself by finding out what happened.
Roger you are correct that the manual shows effects in front of the pedal. I was using the sequence they usually recommend in a pedal chain of having the reverb last. Apparently that doesn't apply to the Session pedal.

[Bill Ferguson]

Obviously I am no expert, but I did write an addendum to the owners manual (attached), showing the proper chain connections.

The Session-LTD pedal should be treated just like the preamp in any amplifier.
Thus the effects should be in line BEFORE the Session-LTD (and soon to be Nashville 400) pedal.

I don't know why it would not work either way, but we just had a issue where the pedal only worked as stated in the first post of this thread.

With a Peavey COMBO amp such as the NV112, NV400, there is an effects patch AFTER the preamp section of the amp. The Session-LTD pedal does not offer this option.

"To use with a sound system (in ear monitors or stage monitors) the chain should be as follows:
Instrument output volume pedal effects Session-LTD direct box sound system input.

To use with a combo amplifier, such as virtually any Peavey combo amp, the chain would be as follows:
Instrument Volume Pedal Effects Session-LTD POST EQ Return (allows use of the amps internal reverb)
OR
Instrument Volume Pedal Effects Session-LTD POWER AMP IN (on back of amp) (bypasses internal reverb)
OR
Instrument Volume Pedal Effects Session-LTD Normal amp input (allows access to the amp tone controls, such as in BYPASS mode on the Session-LTD pedal)"


Hope this helps.

My buddy Ron Forrest made this for me ... If you're JUST using the LTD just take everything else out of the chain ... This works great for me... Sorry it's taken so long to stumble onto this Larry.

[Larry Dering]

Dale, thanks. It's no big deal but caught me off guard. I guess there's quirks in certain gear that needs discovery. I like the pedal and plan on spending quality time with it. I split my use between the Tonex pedal with cabinet and the LTD into an amps return. It's bone chilling cold here and a foot of snow expected tomorrow. If the power stays on I will have something to do with my time. If not I will be seriously busy keeping warm.
