Greg’s Amp Repair

Wow, super nice guy and he helped me out in a pinch! I went in for a preamp tube but he checked out the whole board and very quickly helped with other issues, probably saving me another trip down the line. I just read his wikipedia and now I feel pretty silly asking him about working with Def Leppard (it was written on a piece of tape in his workshop). This guy lived it, yet he is chill and modest to boot. I’d definitely recommend him to my friends.

Greg is a great person and he’s on his game when it comes to this stuff. A true professional.

Greg Leon is a musician first. He is an L.A. guitar legend and he shreds.
He is totally on point with a guitarists needs to accomodate their style of music. He fixes amps; very professional and clean work. (amps were Marshall heads)
He did an awesome job setting up my LesPaul. IT ROCKS!
thank you Greg!!!

If i could give greg 10 stars i would!!! He is fast at his work and is a heck of a nice guy. most of all he knows amps. I took in an amp that is a one of a kind and now this thing purrs like a kitten. Thanks greg!!! I will never go to anyone else for amp servicing.

I took my ES-​175 to Greg for a set up and he noticed that is was buzzing way too much even for a Hollowbody. He added another ground wire and the guitar was almost silent. Along with a neck adjustment the guitar sounds much better and is more playable. I love hearing his stories about EVH, Quiet Riot, Rough Cutt, Dokken and his good friend Randy Rhodes. Check his albums from the Greg Leon Invasion, amazing guitar work and a really nice guy.

Such a nice a guy been a while since we visited him last. Can’t wait to get my head back.

Took to Greg my 1983 Marshall JCM 800 which was outfitted with the 6550 tubes as was standard back then for American JCMs, and had him convert to proper EL34. sounds soooo much better, the turn around was very fast, and his price was extremely fair.

Greg is the man. My fender hot rod deluxe was acting up and Greg fixed it. My amp wasn’t distorting and it would make a gross screeching sound whenever I moved it. He changed the preamp tubes and went through and resoldered all the bad connections. Now my amp works perfectly and I would say better than when I got it. Greg does great work for a more than fair price. If you’re having amp problems Greg is your guy. I wouldn’t hesitate my amps to him. Btw he is killer on guitar and he knows what he’s talking about.

Greg is THE MAN! He had my amp diagnosed and fixed in less than 2 hours, and it cost less than half the «diagnostic price» asked by the other amp repair shops I called. He was professional, courteous and thorough; what else can you ask for?

Greg is the real deal. I called him up to have him mount my amp chassis to the head cabinet for a new amp I had built as well as install and bias the tubes for it. He was super cool so I also dropped off my 5150 to have him clean that up, throw in some new tubes and give it a once-​over to make sure everything was in good shape.
He called me the NEXT DAY to let me know everything was ready to go. The price was very, very fair and everything sounds amazing! He’s definitely my go-​to amp guy.

Greg Leon is awesome!
Service: spectacular! Quality of work: extraordinary! Efficiency: it doesn’t get better!
The bad news: Greg Leon is human. Meaning, some day he’s gonna croak and on that day we’ll all be screwed.
I went out on a limb and purchased a used Marshall head online through Guitar Center. (Yeah, I know.) When I went to pick it up, I paid for it, and halfway to the car the GC associate tells me the amp has the tubes removed for shipping purposes and when I get home I’ll have to put it back together. True story.
Obviously, I have never bought a car – used or brand new – and upon pickup was told that I would have to put it back together when I get home; not knowing if it is or isn’t broken at the time.
Do you know why this analogy works? Because both automobiles and guitar amplifiers need an experienced and educated technician for PROPER assembly, and therefore PROPER functionality.
So I explained to the GC associate that since sodomy fetish is not my cup of tea, there was NO WAY I was taking an amp home in pieces unless 1) I was going to be refunded the amount needed to have Greg put it back together and bias the tubes, and 2) that if I wanted to return it for technical issues I would not be told «we’re not taking the return because we don’t know what happened to the amplifier after you left the store with it.» Of course Guitar Center didn’t want to accommodate either request – so, I called Greg on the spot to try and get an expert involved, and right away competency seemed to have just shinned from the heavens. He explained that I was indeed correct: in no way should a Tube-​Amplifier-​Ignoramus such as myself go home and attempt to re-​assemble the amp, especially without a PROMISE that no matter what happens I would still have the return policy honored.
So, I took the amp to Greg. One of the tubes was blown, and he fixed it up in minutes. I also had him check out my 4×12 cabinet, which I also bought used at GC, and sure enough two speakers were unhooked, and some screws were loose. He fixed all of this up in minutes while I ran to an ATM. All in all I was there about an hour or less and he charged me $ 60 for everything. I don’t have much experience taking an amp anywhere else, but I can imagine it would have been more expensive, and I would have had to leave it and picked it up days later.
Obviously, I won’t be taking my amp anywhere else in the future.

Good guy, worked on a couple of amps for me. Total pro, no jive.

i went here a couple months ago/​The location is a bit hard to find for me because he does it in a garage in a residential area. you gotta go inside a drive way to be able to see it.
However, his service were great. I took in my fender hot rod amp for a repair because somehow it wouldn’t turn on. He told me that he’ll need a couple days to take a look at it and give me an estimate (cost & time). But before i left he said we just wants to take a look at the tubes really quick. and it turns out that i just need to replace my tubes. He was really nice and gave me some tips about how amp tubes works and how to take care of them (since im a noob at these stuff). and he gave me a cheap price too for the tubes. cheaper than the price at amazon or ebay. Paid $ 90 for the preamp tubes and the powertubes. and $ 20 for his service. I’d say that pretty effin’ cheap considering all the other «Fender Authorized service-​center» charge $ 50 just for an inspection. it wouldve cost me like almost $ 200 or even more somewhere else.
I just got a new (used) amp head [bad cat lil’ 15]. I’m planning of bringing it here to get it checked out and make sure that everything runs properly. I recommend this place if you need a repair!

Greg is very helpful when it comes to amp repair. If you are looking for a trustworthy technician, this is the place to go. I dropped off my bass amp to be repaired and it was ready within hours. The location is in a residential neighborhood so it’s not busy and parking is easy. Definitely recommend this if you are looking for any kind of amp or speaker repair!

you know, i would begin to say with, it’s really hard now a days to find a technician that also a musician, and i am not talking just playing music for your hobby, but a real musician. if you google greg leon you will know what he had accomplished as professional hard rock musician in the 70’s.
So, one of my amp reverb had died, so i was looking for a good honest amp repair guy to take a look on it. Some of the guys i spoke to before greg doesn’t even want to take the amp in, because it was too boutiques. it was one of my custom build max butler amp. Anyway, to make story short, i finally called greg and drop it off the next day.
it only took him one day to figure out the issue after he get the new reverb tank replacement and he fixed it right away. the reverb worked now, and took it to a show at House of blues last sunday. If i woudl taken the amp to other amp tech, i would probably never ever play the amp last sunday, because amp tech usually back log the repair request for weeks. you would be lucky if you can get back your amp in three weeks time. But greg get it done in no time.
Also i wan to make a note on how much gracious and humble greg was, i wasn’t even know that he was The Greg leon of the fame Dokken and quiet riot. All and all, i am glad i took the amp to greg, since he is a player and he knows that most musician has tight budget. if its other amp repairmen, the cost to fix my amp would cost me my arm and a leg.
so thank you greg for such a great service and honesty.

Im a full time player, and was looking at a 6 week turn around to repair my Marshall head. Then by chance, I found Greg’s Amp Repair. So lucky I did! He had my amp sounding/​working great in no time at all. The real deal in quality, friendly service, and the guy knows how to play too. Highly recommended!!!

Greg repaired my amp quickly, has affordable rates and was a pleasure doing business with. The fact that he was in La Crescenta was convenient and saved me the headache of having to take my amp to someone in the Valley or the pit of hell known as Hollywood. Highly recommend!

greg leon is the best ever!!! totally honest!!! very reasonable prices !!! knows his tube amps. and hes really hell of a guitar player. and knows his tone.

Greg Leon is an absolute class act and a great guy. As mentioned below, he is an expert on vintage gear and fixes it right the first time. He is super quick and extremely reasonably priced. I really can’t say enough good stuff about Greg. And if you don’t believe me, scores of pros take their gear to Greg too. It’s not unusual to see the likes of Allman brothers’ amps in Greg’s shop.

Greg used to have a guitar, bass, and amp repair shop in Hollywood on the corner of Vine/​Rossmore and Melrose, across from the Vons. You’d take your gear into this old VCR repair shop (yea, VCR repair in the age of DVDs!), and Greg would provide outstanding service at a very fair price, with a fast turnaround. One of the best things about him was that there was no B.S. (like at Solutions or other places), he knew his stuff and fixed the problem right the first time, and he knew his customers (ever tried getting something repaired through Guitar Center?). Well, I drove by his old shop and was heartbroken that he was gone. Google searches turned up nothing.
But he’s rebuilt his shop behind his house in hilly La Crescenta, and I had to get him out there in the digital world (and onto the world of Unilocal). Same great service, prices, and turnaround time, and an even happier Greg. Can’t say enough good things!
Call first– he’s by appointment only. Also offers pick up and delivery, repairs pedals, and is a vintage specialist.
