You're SO right about that! Sometimes you really have to listen closely to options to see if there's a difference..and even then it can be a toss up. But this thing that you found...it's glaringly obvious to the most casual of observer. The sound is so much more clear with your settings... the "volume" knob down low controlling the listening volume and the "master volume" knob set to 12, controlling the "most awesome sounds possible" circuit, hidden within the amp. The results are significant! Thank you so much for your video! Much appreciated:)

So simple, but really is the best advice for this amp! I have owned three of these due to selling to get bigger amps, just played my first live show using this truck and it killed it, cut right thru the mix without a mic, thx!

I'm an EQ and tone fiend and I've had my BJIV for about a year now. I have spent that time constantly pursuing a good tone. I've been through at least 5 guitars, 4 overdrive pedals, and have messed with every tone shaping knob in my chain. No matter what i did it just always sounded flat and dead to me. I've been utterly dejected over this. It was starting to take the joy out of guitar playing. Well, this very evening I was at my wits end and finally searched "how to dial in fender blues jr" and came across this video. I paused it, flicked on the BJ and tried it..

Terrific "trick." I was having troubles with volume on my church's Blues Junior IV this last Thursday, and I could not figure out what was wrong. It's a shared amp so other people have moved the settings here and there. Now, though I suspect that most of the volume/tone suck was coming from a defective, VERY long instrument cable going into my pedalboard from the amp, I applied your suggested settings Sunday morning during rehearsal (along with a new, much shorter instrument cable) and I've never heard such glorious tones coming out of it before! I only took the the Master up to 10, put the Volume at about half past 2 and it was amazing! Never sounded so good during the church services as it did yesterday morning. Thank you!

This works so well on my Blues IV ! Thanks for the tip!

That live recording is not only superb but the guitar and amp sounds beautiful!

such a simple trick with a huge difference when I started doing that it was like I got new amp great tip

I totally endorse this tip. I run my BJ (Texas Red version) the same way with the master volume always on 12 and control the volume using the normal volume control normally between 1-3 depending on the size of the room I am in. The amp sings and takes pedals really well.

Thanks a big lot for your videos on this particular amp - I bought myself the same model and am more than happy with it! I found the lacquered tweet version with the Jensen speaker with its crisp sound much more appealing than the regular, black one. I really love that clean sound with the master control high and the volume low. But as I don't use pedals I'm really delighted of the dirtier, crunchy sound created by the opposite position with high volume and low master. I totally agree that more than 2 or 3 on the knob is ear killing in normal rooms... Thanks a lot again!

I have been using mine for 8 years or more and have never tried this before .....THANKS !

Bro thanks alot for this tip been using my for a couple of years and I've never heard it sound so good... iam gonna start taking it out more often

aaaaaaaa.... very smart, I will try this tmr when the house is not sleeping, thanks a lot for sharing!!!

I do the same with my silverface master volume super reverb. It sounds amazing. Great tip!

Thanks for the tip. I really like the way you organized your workstation, I havce a similar style of desk gonna try some of your equipment placements. Thanks!

Thanks so much - had thought about selling my Blues Jr. III but no more. Now it is a whole new amp and has much better tone!!!

Was getting super frustrated trying to get a nice tone out of my BJ III leading up to my first proper paid gig. This tip sorted me right out and had a great gig because of it. Thanks heaps mate!

Thanks for the info! Can't wait to give it a try.

Works amazing ! Thanks

I do this with all my valve amps with a master, it brings the amp to Life, even recommend it for the boss katanas. It's killer for jcm 800s

Good tip, I've always set the master up/preamp down on all the tube amps I've used. It just makes the thing sing and be more sensitive to picking attack.
