I was hoping to get some help with this, but I'm relatively new to amps and such so forgive me if my terminology and descriptions are off.

So I use an Orange Rockerverb MKIII as my amp for playing stoner/doom type stuff. I have a pedal called Acapulco Gold, which is a one-knob pedal that imitates the sound of a cranked Sunn Model T. I often will turn up the gain all the way on the Orange and then also turn up the pedal all the way, which leads to a tone that I really like. My problem is even if all the strings are muted I still get so much distortion and the overall sound is just incredibly muddy. I can turn down the gain or the pedal which will clean it up, but then I don't get the tone I like and even then I still get noise coming from my amp. The only time I can mute the strings and the amp is silent is if I switch off the pedal completely. Does anyone know how to fix this?

so you like the tone but also the tone is incredibly muddy?

Also if you are cranking the gain on your amp and your pedal chances are it will be very distorted and muddy. The acapulco gold and pedal like that are usually meant to be put into a clean amp to use the pedals again to get the distorted tone

I love the muddiness of the tone when I am playing, that's why I'm using the pedal through the dirty channel. My issue is when the strings are muted or I'm not playing there's still incredible noise. I think a noise gate is the answer, as this thread suggested.

GreatGreen posted:

So just to be clear, with sound, most people associate the word "mud" with overbearing and undefined lows/low mids, with lacking definition in the treble frequencies when you're playing. Is that the kind of mud you're talking about?

Or when you say "mud," are you talking about how much garbly white noise there is when you're not playing? Because if that's the case, most people will be confused by that because that's not how most people use the word "mud."

I apologize if my wording was confusing, I can understand the issue here. I may have been using both interchangeably.

Going by your 1st definition of mud, the problem could be described as "I love the muddy tone using this amp-pedal combo, but the white noise when I am not playing is a problem". That problem could be fixed by a noise gate, as this thread suggested.

It might help. It depends on where the noise is coming from.

If you crank up your amp, and then disconnect your guitar from the amp, do you still have noise?

Maybe, but I don't think so. I'll have to check when I get home.

The noise is definitely coming from the pedal I think. When I crank the gain on the amp all the way and mute the strings it is silent, when I add the pedal is when the white noise comes in.

I've got a noise gate coming in today so I'll report back and see how that goes.

Update: I got an ISP Decimator II pedal and it pretty much fixed the problem. I still get a tiny bit of background noise but that's because I'm playing with just too much gain. It's a bearable amount and doesn't bother me. The tone isn't really affected at all from what I can tell.

Thank you all for the suggestion, it worked!

This might be a dumb question or the wrong place, but as somebody who has no knowledge of electronics, where do I start with working on my own amps?

I know it's extremely dangerous, but I'd like to be able to do it on my own (safely) eventually. Is this something one can do as a hobby or is it more a "go to school for it" type of thing? Where do I start? Are there starter kits or something that are safe that one can tinker around with?

Sorry if this is vague. I'd love to be able to do maintenance/modifications on my amps safely but have absolutely no clue where to start on anything involving amps and DIY.

Aren't Mesas basically the worst thing to fix? I seem to remember amp techs refusing to touch then because they're crammed full of a billion components in way too little space.

I havent worked on a Mesa yet since I only started recently, but in the shop I apprentice at we straight up refuse to fix certain Peavey's because the chassis are set up in such a bizzare way no amount of $$$ is worth the time and frustration to fix them. Ill ask the boss man on Tuesday which models they are since I forget and report back.

I've never seen a tube tester built INTO an amp before. Anyone know whats going on here? The one we have at work is HUGE I cant imagine one fitting into a chassis with an amp. But then again that one is analog.

Hey everyone I have a little bit of an amp mystery. I have an old family photo from what I believe is either the 30s or 40s, and I'm trying to figure out what amp is in it:



It looks like its being used to amplify the lady playing guitar in her lap, as thats the only instrument with pots on it. Unfortunately I have no way of identifying that lady so I cant ask her or her descendants about the amp.

You don't need SS for apartment playing. I live in an apartment and play all my tube heads ranging from 5-100 Watts. Just need a good attenuator.

Pick one, as others have said. You can try all you want but youll never get the sounds youre thinking of with tiny bedroom amps, tube or not.

the HiWatt Hi-5 has a goofy name but is the greatest bedroom amp if you like distortion. Gives you heavy tube tones at reasonable volumes.

Otherwise as others have said the Katana is great for more clean stuff.

Weber Mass, or any Weber attenuator is what I use. You want one that actually has a load. Avoid "volume pot in the FX loop" stuff like Little Black Box unless you want a lovely attenuator-like thing for ultra cheap.

Hiwatt Hi5 is a 5Watt amp with amazing tone that is reasonable at low volumes, put a treble booster in front of it and it just sings. I use it in my apartment and have had no comaints from the neighbors, and it also can get loud af when I need it to.

Can someone help me with this layout for an amp I'm working on? Specifically my question is what is the difference between the dotted wires and the solid wires?

Are the solid wires wiring I'm supposed to do, and the dotted wires PCB traces?

I have an Orange Rockerverb MkIII i treated myself to some new tubes. I was going to retube and bias it and discovered apparently Orange put some sort of auto-bias system in their amps around 2011? This was purchased new from Orange around 2016.

I've never heard of it before or seen anything referencing it on the amp. Should I just bias it like normal?

The Orange forums are painfully unhelpful. You can't talk about any sort of amp maintenance without Orange saying "take it to a pro" and banning you.

For tube amps they're great, just make sure you get an actual attenuator like a Weber and not just a volume pot that goes in your fx loop

Anyone here build their own tube amps? I’ve been an electronics hobbyist since I was a kid and have done several pedals so I’ve decided to try my hand at a low wattage amp. The only parts I’m having trouble trying to source are quality transforms so I was hoping the thread had some sources. I’ve been looking at tube depot and don’t mind the prices but they’re out of stock for what I want.

Fwiw there's a worldwide shortage of transformers rn (or at least thats why the folks at mojotone claim to be delaying my order 😡)

Post technical advice then, you didn't help out The Demilich with his speaker question at all. Share your knowledge with us. I'm here for it.

I don't have the answer to his questions. That's why I come to this thread. To learn technical stuff.

I am failing to see how "blow up your poo poo" and have someone replace the components that failed or the amp itself is anything close to good advice. Let's assume that everyone can afford that, which is absolutely not true, even then I don't want to blow up my amps, I want to learn how to AVOID blowing them up.

I have amps that sit at home all day. I play through them every single day, I enjoy the hell out of them. Just because someone's not touring doesn't mean they aren't legit musicians or something. And even if they're just hobbyists, what's wrong with that? What's wrong with enjoying your amps at home and having fun with them and taking proper care of them?

Actually it will help you its called electrical engineering and is the science we use to make amps. Its not like music theory where its all subjective to taste, there are actual laws of science governing here.

It's even funnier now that it's obvious you know literally all you have to do is match impedance and wattage.

This is like going into AI for car advice and having some dude back up their terrible advice by going "just use the accelerator instead of the brake, there's no rules here it's all about feel man. I've crashed my car like 400 times so I'm pretty much a rally driver".

Giving advice you objectively know is unhelpful and stupid because "everybody knows that poo poo already" is arrogant, condescending and a loving dick move.

You don't know where someone else is on their journey or where their knowledge gaps are.

No one thinks you're a legend for deliberately being a dumbass. gently caress unless there is fire involved blown amps don't even look cool to the audience, you're just quieter or silent for at least ten minutes if you have a backup

Gonna get a Mesa some time tho. Because, well, Mesa.

I got paranoid about Gibson loving up Mesas and bought a MkV 35 Watt when the sale was announced and I have no regrets because now I have a Mesa and it's awesome. So much tone to chase just plugging direct in, let alone with pedals.

Plus I can bring it to my jamband friends and metalhead friends and itll sing in both situations!
