Volume Box on eBay???

Hi Jerry

I am curious to get your opinion on this item I found on eBay.

cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7382941276&fromMakeTrack=true

It looks suspicious to me, like it could damage an amp, since it runs in the effects loop.

I have a multi-effects processor (with a separate level in knob and a level out volume knob) that I occasionally run in my 5150's effects loop. I breifly tried something like this once, turning the level out all the way down...cranking up the 5150's pre and post gain volumes, then turned up the level out on the unit... and while it WORKED, I only did it for all of about 1 minute, in fear of damaging my amp or the multi-effects unit!

What kind of damage, if any, would this guy's "volume box" do to an amp? It seems like it's acting like a MASTER VOLUME, but since it's in the effects loop between the preamp and poweramp stages, is it really getting both the preamp tube AND poweramp tube gain? I thought that maybe something like that would put too much resistance in the signal path...but that's why I'm asking YOU!!!!!

Thanks!

That won't damage your amp. It really won't do much of anything for your amp. It's nothing more than another master volume placed right after the amps master volume. There's no real benefit that I see to using one with a 5150. The amps master volume will do everything that box will.
