Hello,
Can somebody explain what's behind the "volume pedal in the effects loop" trick? What problem is being solved by doing so? Are people doing that to enhance tone in some way?

Don't really know the technical specifics but when I put my volume pedal in the loop I can turn my head up with the volume @ noon and it sounds great . This allows the tubes to saturate and poor out that killer tone and I can keep it at bedroom volume . Without the volume pedal in the loop this volume would kill unborne children . or if you try and keep it at bedroom volume without the pedal it sounds like crap .
btw the small blocks sound better everyday .

The QR sounds best LOUD... and it's really loud. Putting a volume control in the FX loop allows you to push the amp without making yourself deaf, as far as i know there is no other notable side effect, though the amp still sounds best cranked.
I have used an Ernie Ball passive 250K volume pedal and currently use a Tube Amp Volume Control Box i got on Ebay for 20 bucks, both work great for this...
Another trick Josh as Splawn told me was to put the solo boost past 9 O'Clock but do not engage it when running a lower volumes, this thickens up the sound as well.

I'll have to contact Splawn to learn more about what's going on with this loop-trick. As far as I'm aware, that should have no significant bearing on pushing the tubes or the output transformer. I'm guessing there's some other circuitry behavior that is being impacted by this loop-trick. The way this loop-trick is being advertised on the fourm it's made to sound as if it's effect is analgous to a power soak, and that's simply a physical impossiblity.

Sonic whatever it is...it works...that's all i care about. i probably wouldn't be able to play this amp in my band if it wasn't for this ;D |

oh...and this isn't for just splawns...this works on any amp with an effects loop (obviously)

in all honesty it's very simple as far as i can tell...
you can turn the amp up as loud as you want..thus working the tubes...but only send as much volume as you care for to the speakers...
i'm no techie though

If the loop is in-between the pre-amp and the power section of the amp then you are not working the power tubes, it's just acting live another master volume. I haven't tried it on my QR because i don't have a volume pedal.
Has anyone tried using an EQ pedal in the loop and cutting the level on the EQ pedal to acheive the same effect (but with the added benefit of some EQ)?

I tried it using an Alesis Nanoverb FX unit, lowering the output on the FX unit. Really lowers the volume, but also kills a lot of the high end. Maybe a straight volume pedal would sound better? |

Just got an Maxon EQ, have not tried it in the FX loop yet, but it's on my list...
And i think Vom is right, turning the volume up pumps more juice into the tubes, it's not much more complicated than that. I would be curious what Splawn says when asked directly.... Whatever is happening it seems my QR comes to life when the native volume is at 9ish O'Clock and gets better as the volume increases. And putting a volume into the FX loop and backing that down keeps a large percentage of the high volume tone intact without destroying my ears.

Im with sonic on this one.....Ive heard several people on here say this volume pedal/loop thing works so I dont doubt that it works somehow, but the way loops work and my knowledge of them, you arent pushing the power section any harder by doing this. It would have to be after the power amp to be able to push the power tubes.

how are you not pushing the power section when you have the amp's volume at noon?

Well.......to me, all the volume pedal does is act as a 2nd master volume. It might work better than the single master, but it still is holding back the power section of the amp. Lee Jackson did some mods with 2 master volume's, and the Metaltronix amps he made had 2 master's also. Its a good idea, but the reality is your never gonna hear what you amp can really do unless your able to do large enough venue's to open it up with no attenuation at all.

How loud do I have to crank it,to get this tube saturation going?  |

the amp is at noon...the power section is working like the amp is at noon....
i use a midiverb in the loop and control the output volume that way...to me it sounds like i've got the amp at noon...tone wise...and i can get that tone with kids sleeping in the other room.
best thing ever
