After changing the tubes to JJ’s in my Fender Blues Junior, the next logical step seems to be changing the stock speaker. Again, I’m looking to compliment that smooth overdriven tone I now get with the JJs. The question is… which speaker? What would you recommend for this setup if you were looking for a good solid Blues tone? The only pedals I use are a Compressor and a Tube Screamer. I play at very low volumes. The JJs were ordered special to breakup early.
I was thinking of buying one or two speakers and making a cabinet for them. I’d have to add a speaker output jack to the BJ but that doesn’t seem to be too hard. Another thing… where could I find plans online to build the cabinet so I make the right size? Open back or closed?
Thanks for the help,
Dan

Are your pre-amp tubes 12ax7's? If so change the tube in V1 to a 5751. SRV used 5751's in his amps, a little less gain but smooths it out a lot.
I am changing mine over to the 5751's and I am loving the rich fullness with less gain.

It's an 8 ohm 50 watt speaker. I am using 12ax7's and although not exactly sure what is in the V1 position, it is different from the rest.
The amp overdrives very smoothly after I installed this set that Eurotubes sent. It lost much of its harshness along with a little volume (not a problem for me). I'm very happy with its sound now after the modification. So much so that I'd like to continue with mods to make it sound the best it can

I'm guessing there are 2 12ax7 pre-amp tubes, one is V1 and the other is V2. If your tubes (pre-amp and power tubes) are all in a straight line V1 would be the pre-amp tube farthest away from the power tubes. V1 is the first tube any signal goes through.
A 12" 8 ohm speaker, let's see...........
Eminence Screamin' Eagle or Texas Heat for American Blues.
Eminence Private Jack or Stonehenge for British Blues.
I have a set of Stonehenge's in my 2x12 cab and I can hear some very early EC tones. I'm waiting for my new Amp Head to come in before I give a full review of these speakers.

" V1 would be the pre-amp tube farthest away from the power tubes"
Hmmm... are you sure about that? I looked around the Internet and thought I read it was the CLOSEST to the amp tubes so I installed it there. If so, I'll switch them around and try it that way.
Thanks for the info.

Dan I talked to an Amp Tech the other day about it. However, Let me know if you hear any difference. |

Ok... I see where I'm confused. I said "closest" to the amp tubes because I was instructed to install the tube that was slightly different in the V3 position and that is the closest to the power tubes. You are correct that V1 is the furthest.
Thanks

OK. Good thing we can discuss these things huh?
Let me know if it makes a difference in tone between where you had it and V1.

Speakers that are often recommended when it comes to smooth overdriven, warm and "vintage" tone are those Celestion 12" Greenbacks. Maybe check them out. Personally I believe that also the cabinet/enclosure has a greater effect on the overall sound you get from a speaker, often this is a play of try and error. No golden rule to follow.   |

Ok…<br>I screwed around with the pre amp tube positions this morning. Needless to say, the experiment was an eye opener. To start, I marked each tube 1,2, 3… so I could go back to the original positions if needed. The tubes are two ECC 83S and one ECC 81 that replaced the three 12AX7 that originally came in the amp.
By switching them around, I was able to get three distinct responses from the amp although there were many combinations possible. In one position, the amp was very clean and resisted going dirty. I really liked the way that position sounded but I’m after early breakup. In another position, the amp would go dirty but had to be pushed a little harder and I felt the distortion was harsher with a little edge on it I didn’t like. In the third position the amp broke up early and much smoother. This was Eurotubes suggested installation so I guess they know their stuff.
I tried all combinations while playing chords and single notes to get used to the quality of each sound. I’m glad I didn’t have to do this with the two power tubes since I noticed those suckers get HOT.
It was an interesting experiment but now I’m back to square one. The thing is, I’m so impressed with the difference a tube change made, now I’m hot to try a new speaker and see if I can get a similar improvement. That’s what sparked this thread.
Thanks,
Dan

Very interesting. I guess I'm gonna have to try swapping V1 and V2 tubes in my amp now. ;D

Haven't had a chance to install and test the texas heats yet but will give an assessment when I do. another good replacement might be the celestion g12h30 suppose to be nice either way if you need speakers, dave has the best prices I could find. E-mail him for a price list. www.avatarspeakers.com/ |
