What I described (more articulate, etc.) was with the low profile OT. I like it.
Alright I think I will go with it and does anyone ever upgrade the power transformer that isn't doing a 6L6 conversion?
I ended up getting the TO20B, because I can always use more bass and it is supposed to be more efficient + lower noise. I will wait to post updated pics once I install the new output transformer.
My dream amp is a Blues Jr with tremolo. With all the different takes on the Blues Jr that Fender has done so far, why not add tremolo?
I feel like the tremolo offered in the BYOC tremolo pedal based off the EA tremolo pedal is better than what is offered in the Excelsior and I doubt we would get much better than what is in the Excelsior for the Blues Jr. if they ever did it.
You're probably right, but I thought the tremolo in the Excelsior was decent enough.
I'm not saying it is bad, just that we can get damn good tremolo through pedals, but I get what you are saying, it would be cool to have a Blues Jr. with one built in.
I don't know what the Excelsior has, but for example, I don't much care for the SS op-amp tremolo in the Deluxe Reverb. The Princeton's tube bias trem sounds much smoother to me.
Any built-in trem in a Blues Jr would almost surely be opamp. I don't see Fender adding trem at all, but I really can't see them adding tube socket(s). 'Cause then you may as well think about addressing the SS rectifier, and verb. And there goes the price point.
I just need classic sine wave, no square or asym helicopter noises. The Jam Chill pedal is fantastic for this. The Catalinbread Pareidolia is different, but also excellent. It emulates the brownface harmonic trem that Fender used only for a short period around 1962.
The Chill is very similar to BYOC's Tremolo Pedal, they both use a single op-amp and transistors to achieve the sound.
(you can see a parts list by looking on the BYOC site for theirs)
Cool. I wasn't aware of BYOC. And yes, the Chill is opamp, but it's not harsh and clicky like a DR. Do you know why that would be the case?
I sometimes turn the depth all the way down and use it as a boost/sweetener. I'm sure it's not all that unique of a trem, but once I tried it, I mostly stopped looking.
I got the Chill to use with my Bjr. Now that I'm playing the Princeton, I don't use the pedal as much. But it is as good as the Princeton's trem IMO, which is saying something, with the added benefit of greater speed range (slower), and perhaps a bit more throb.
So if we are here to Meet the "Ultimate", how's about some sound clips?
It's in quotes for a reason and I don't have any hardware to do a sound clip that would be better than a phone or crap digital camera. If I can get it to my buddies house I will mic it up and get a clip for sure (but that won't be anytime soon, since that is a 2.5 hour drive, I'll get it eventually though).
Edit: I just asked him actually and he may be coming my way to do a show and he said we could mic it before the show. So it may not be very long.
New Pictures w/ TO20B Output Transformer and Clean Boost Module w/ Footswitch Installed. You'll notice a few difference since the first pictures
New and Old Output Transformer:
BillM Clean Boost Module Installed:
Stereo Footswitch Mod w/ Line Out Mod (BillM):
I believe one of the other mods I didn't have before was the Standby Switch, which is now installed.
Finished PCB w/ Mods:
I thought someone could give me tips on wiring management, I don't think mine is managed in the best fashion and I've heard wire management does affect sound quality (mainly noise). Or do I already have it about the best I can do?
Is it noisy?
Mine was always pretty quiet, but I sit close to it, near a computer, for hours at a time. I took it to my tech for a look-see, and he said he re-routed a wire or two, and now it's so completely silent I can't tell it's on. So, it's certainly possible to achieve.
I'd look in mine, but I don't want to pull the chassis and inflict yet one more bending on those poor ribbon cables.
If I recall, billm recommends carefully bending the ribbons so they hug the chassis. EDIT: I had it backwards. He pulls the ribbons away like yours.
Also, twist your filament heater wires together, and move them away from other stuff, crossing at 90 deg angles when necessary.
I'm not an expert like many here. That's just what I recall from working on mine a few years ago, and general recs from David Allen, who's Encore kit I'm just completing. Note the twisted green & brown filament wires, and their positioning in the Encore:
Poke around on billm's site, including reading his replies to comments. There is some info there on wire dress. You could email him, too. He's a helpful guy.
Nah it's not noisy, but I thought I could do better than how it is now. Yea I've talked to Bill a few times on a couple subjects, very helpful.
I guess I'm just looking to beautify it up now
Thanks for the tips though.
Hey guys, I thought I would bring this up since it may have to do with my Blues Jr.
When I turn on the BYOC 5 Knob Compressor the volume on the guitar has absolutely no effect on the overall amp volume; is that normal for a compression pedal?
My other question (again) is do yall think replacing the power transformer is worth the cost ($80) if I'm not planning to switch to a different tube setup like 6V6's. What would the benefit be besides a more efficient power transformer? Is there something it would help with due to it being a better transformer than the stock one.
Here is Bill's page on the PT: http://billmaudio.com/wp/?p=1128
I doubt you'd get any sonic benefit by upgrading your power transformer, if anything you might lose some sag and tighten up the bass and make it sound less tubey.
Any idea on the Compression Pedal deal? Could it have to do with being in front of my Visual Sound Buffer (stand alone)?
I'd really appreciate it if someone can give me a quick answer on the compression pedal completely disabling any volume control from the guitar's volume knobs. I never ran a compression pedal until recently, so I wasn't aware if this is supposed to happen or not.
