No way man. What's the point in that thing when all it does is limit the preamp from hitting the power amp as hard? Isn't that part of the cranked tube tone, having the preamp hit the power amp hard and saturating the tube? Sure, it will get the amp's volume up, but it's not going to do the same thing as an attenuator.
Thats what I thought too.. but some of the wording in the auction is a little misleading....
I don't think this is correct. The same principle works on my Rivera or any amp with send and return controls. You simply turn up the master and volume as loud as you need then reduce the return volume. It definitely works, at least on my Riv.
It might be useful if you had an amp with an FX loop and no gain control. Is there such a thing? Otherwise it seems to have no purpose.
Also you could just spend an extra $11 and get a Dano F&C EQ to do the same thing (level control), plus you get an EQ.
The entire Hot Rod Deluxe series amps have no FX loop gain control.
Is that some type of faux-attenuator?
thats the way they seem to advertise it..... but...
Isn't that just a volume pot in a box?
yes. volume in a box.... i used my katana like this for a little while when i was short on pedal board space... just pulled back a little bit of the master volume, but def wasn't an attunator.
Yes...it's a volume pot in a box. The schematics are everywhere. I had one for my HRDx. The guy also makes them for Peavy amps. Anyway...it is what it is. A bit noisy, but it's a poor-man's hotplate. It'll get you close, but no cigar.
I meant FX loop and *preamp* gain control.
It is the exact same thing as adding a master volume to the amp, inserted where the loop is.
Most master volumes I've seen control the amount of signal feeding into the power amp. The can be implemented several way, but they all typically do this.
This box is just adding a volume pot in series with the pre-amp signal, right before the PI. If you look at this schematic of an early mesa boogie you can see a master volume implemented this way. It is right after the pre-amp (in the top left hand corner), and right before the PI.
Controlling the actual volume of the power section (varying how much work they do) would be more like power scaling.
It's just a pot in a box with a couple of jacks. It is absolutely not a Master Volume, or an Attenuator.
Build one yourself for a few bucks.
