Tames the beast!

Picked this up when I ordered my Fender Blues Deluxe Amp and it does what its designed to do. The good folks at JHS make a fine product. My loud amp is now controllable with this little inexpensive doodad. I can crank up the tubes and play it at room volumes or anywhere in-between and still get that classic tube break up. Highly recommend this device for those that have an out of control tube amp and want to stay in the neighbors good graces, i think it would be great for an apartment too if thats where you are. Just get one, it doesn't mess with the amps sound at all. Doesn't come with patch cables so get a couple 6-8" lengths right angle to straight. Waiting for mine to get here and had to use what I had from a pedalboard supply.

It just works

I have used this with 4 tube amps. All with great success. I hardly ever used an amps effects loop until now. I usually use a floorboard {ME-80} or pedals with tube amps. Or straight into the amp itself if it's a modeler like my Katana which has its own floorboard. If your amp has an effects loop and you want to get a decent cranked sound at a reasonable volume, this is for you. I even use it on my Marshall DSL-1cr and DSL-1h one watt tube amps cranked for "midnight" and wee hours playing. For bedroom and apartment players, it's worth its weight in gold. For clubs/bars you can take your "big-boy" amp, set it where it sounds best or crank it and just dial it back for the room your gigging while retaining your amps piss and vinegar at less than ear-splitting volume.

A must have

This thing is great. Allowed me to get the fullest sound from my head and cab at manageable volume levels. A must have.

Perfect for a hot rod deluxe

I own a hot rod deluxe and without this there is basically one tiny spot on the volume knob that is usable. Now I can turn it up to 12 in my bedroom if I want.
Rated 5/5

Perfect!

I have a Fender Hot Rod Deluxe and it is super loud! Too loud to use in my music room comfortably and this little box was the answer. It allows me to crank up the amps volume to reach the sweet spot and then turn the overall volume down without loosing the tone quality. This thing is worth every penny and more. Highly recommend!
