IMHO you performed a miracle healing here…
Amp sounded fab on the final demo, very naff before. All decisions made perfect sense. You can't please everyone but the outcome spoke volumes. We're all the final demo settings with channel jumper in place? 🙂 👍
Great work! I like the methodical way you approach repairs and the way you explain it is very easy to understand. I think if I spent 8k on an amp that sounds like arse I might want to give up playing but not really. Just so sad for this guy.
Great series mate, I really enjoyed this. I really enjoyed the commentary too 🙂 Plus your not a winger, you are telling the viewer what you seeing in front of you. I love the honesty. Keep it up.
lazy jackass gets big bucks
Thoroughly enjoyed this series, cheers.
Like night and day. Excellent work!🤟
Lazy J: why would you go through soo much work to handbuild an amp without nailing down your circuit design? Giving boutique amp market a bad reputation. shame.
Brad, in your opinion, did it pass the "cold chisel" test ? 😉
Hi Brad !There is no need to worry about the speaker . New Celestino blue can handle much more then 15 W. The new ones have different cone material in the center. So is more build like for 20-30W
Sounds great now , great job as always👍🏻 curious if you ended up adding a grid stopper to the cathodyne , sounded really good and without that annoying(to me) sound of the cathodyne 🤣
$8000? Even $8000 AUD in genuine Aussie bogan bucks shows I REALLY REALLY need to raise my hand built prices. Keep pooping on it, Brad. It's just begging to be shat upon! I do build split chassis amps (2 cans ala Valco), but the ONLY things in the bottom chassis can is the mains power supply, filtering, the audio output, and the tremolo. I'd NEVER put reverb in the bottom can. Magnatone Estey era did split chassis amps too. Power supply PT filters & OPT ONLY for Maggies. This Wobbly J amp is the crap I might have built when I was 16 or 17 years old and still smoking lots of weed.
This is a very poor quality amp! I don’t know why people are buying these amps. I’m an electronics engineer I can’t accept that companies are selling this level of quality with the label “boutique point to point” amp. And the architecture of the amp add a lot of other problems to the table. Just buy a Brunetti if you want quality or a Fender or Marshall for availability and world wide support.
just found ya channel the other day its great. ya should do a shit talking amp show with Brad the guitarologist. both your personalities would be a funny combo i reckon. rock on mate
Great video Brad..Love the amp after the corrections..Top man..Ed..uk.😃
I feel bad for whoever shelled out for one of these things.
Brad are you a Norm Macdonald fan? The "don't count your chickens" reminded me of his uncle Terry story
6:54 – Brad engages the NO switch.
your playing sounded rad!
You mean nothing to me!!!!!!!!aaahahahahahahahahahhahahaha
Great engineering work. Night and day difference in sound.
You are smart and entertaining. However, once you start throwing F bombs, you lose me.
I don't know if it's mentioned in another comment, but the carling switch between the preamp tubes is a bass cut, where IIRC the coupling caps are reduced in value.
Brilliant work as always, even that cringey end line was just *chefs kiss*. The annoying thing about these 5E3 style amps is the interaction between the two volume controls, even when plugged into only one input.
Your explanations are damn helpful. Great work man, love the channel.
5:13 Brad in a nutshell! I LOVE it! 9:27 London Power would like a word with you Sir…;)
12:40 sounded like the football scene in Flash Gordon. Go Flash go!! Love the 4 videos!
Yep sounds great..not enough headroom for my style of playing but as long as it delivers safely & reliably what the owner is looking for..👍😎
"If you don't like it F off" 🤣😅🤣 Brad rules!!!
I have a Tektronix 2235 with cart I got for free that I haven't used on an amp yet, I would love to see a short video on how you use yours to motivate me.
I think it would be nice to know if this has been modded or “fixed” by someone in the past, or if this is how these things ship from the manufacturer. Seems like a scandal and afaik they have a strong reputation among folks who I think would know (that pedal show)?
Dude great work 👍🏼. I imagine the goons on TGP are foaming at the mouth by now.
Great series Brad, Sounds great now. I happened, by accident, to listen to the 2021 Tone Talk with Dan Steinhardt from TPS . Both he and Dave Freidman love Lazy J amps & talk him(Mr.Lazy) up heaps. I guess there is some magic in an amp destroying it's self. Sounds best 2 minutes before it's death. EVH destroyed a lot of amps to get his sound (apparently). But I think you've saved this one. Where's the "love" button – "like" is just not enough admiration for you "like base life form"(oooo smooooze). But seriously – Top job! & Negativity SSSSHHHHMMegativity. MEH! (where's the T-shirt?)
Wow. Just wow. 8 grand for awful. EDIT: sounds better at the end. Nothing worth even 3 grand but better.
I've watched the complete series. What I've learned is that the Lazy J J20 isn't worth anywhere near what they charged for it. I don't think there's anything wrong with all with pointing out all its flaws and deficiences.
Came here expecting to hear talk of mythical tone difference between tubes. Stayed and listened to Brad explaining exactly why he changed the tubes and exactly why they make a difference to the overall sound and heat issues of the amp. There's so much garbage on YT about "toan" with electric guitars that I almost "kneejerked" when I saw the thumbnail, but the idea of a lower output giving you that bit more break up edge for some cool blues feel makes perfect sense. Been subbed for a while now as have amps I need to find time to repair in the back room, but between my – long lost to a period pf desperate musician poverty – Marshall Bluesbreaker and my current (of all things) Harley Benton Tube15, you just can't beat a simple, old school tube amp. Fair do though. the new non-tube amps are getting close and for recording my ToneX IR Modeller makes life so much easier getting that sound I want. But at 58 and 48 of those years clamped to a 6 string electric, I'm so pleased to be proved wrong and to learn something from a master of the amp repair art. Top work mate. Fascinating stuff.
I learned so much… Thanks
Must piss you off to think people are going to say “That sounds great!” giving full credit to Lazy J.
Heard about these amps but never had one on the bench before. Now I’m forewarned. Thanks for sharing. Definitely not worth the money. A 5E3 is perfect in its stock form. No need to add all that extra crap to it and double the price.
Great work. I can't get over this amp: it's disgraceful. Agree regarding the grid stopper on the PI. It makes the volume range useful all the way up. Well, if you like the sound of a collapsing power supply. And sometimes I do. 😉
PS – Not sure it handled Cold Gravy. Needed a bit more headroom, I reckon.
I watched all the episodes on this amp. Giant transformation into a really exceptional amp! You are are one of the very best amp techs on YT! With all your hard work, I trust will come good fortune!
Frankenstein of an amplifier….just looking into the back would have scared me off! What a shocker
Sounds like the owner should go for some more highpass filtering with these new 6v6s. I actually think it worked with the 6L6s but after the change it just cant keep up with that low end i guess 🙂 hard to say for sure from just those clips but i think thats what I'm hearing. Very nice series, will return for more kit and banter
Hey Brad if your after pickups hit me up. Fuck that Larry Dimarzio fella, dont give him your money.
Their website shows that their amps start in the mid $3,000s US – which is too much for an amp put together like the one you showed. It looks like someone's personal kit amp they bought off StewMac with all the handwritten labeling with silver Sharpie! In fact, I think the StewMac kits are higher quality and they are half the price. There are lots of amps that sound great – but they need to not break within a couple of years of buying them. Who cares how they sound if you can't use them?
5:15 Whinge? LOL
Hey, its your extensive experience and hard "yakka" (I just found this word while searching for "Whingy") that brings me here.
Basically, I'm here to learn from an expert the good and bad design/build for different amplifiers.
I'm not sure I'd tune-in if you weren't at least a little whingy!
Today has been a good day, I've learned two new words as learning I should avoid Lazy J amplifiers.
Dunno if it helps mate, but in the earlier Lazy j's the switch underneath used to change the preamp supply voltages to give a bit more or bit less voltage to those nodes. Don't know what it was doing in the one you have there, but it may explain that extra 1K5 that was shorted across.
All the best mate
Shane👍
