Wow, a cool amp at the best possible price … free! Those Plush amps are pretty reliable workhorses, and make a great loud and clean platform from which to build on, very similar to a Fender Twin Reverb.
Amp Man, Someone recently gave me a Plush P1000S 100-watt tube head. I retubed it with 4 Mesa 6L6 tubes on the power section, and I purchased some 12AX7 Groove Tubes for the preamp section. I also picked up a used Boss overdrive pedal. This thing is sounding better than great, but there are two items I can’t figure out. First, I am getting a buzzing sound when I turn up the reverb chamber (anything past 2). When I keep it turned down, it is more or less very quiet. It does have the standard buzz when I take my hands off of the neck. Second thing is, while I have a pretty good tone, I can’t seem to get better definition out of my notes. The lower strings tend to sound muddy while soloing. The high notes are fine, and actually have a really cool tone. Any help would be great. Jim |
Wow, a cool amp at the best possible price … free! Those Plush amps are pretty reliable workhorses, and make a great loud and clean platform from which to build on, very similar to a Fender Twin Reverb.
First, the reverb issue. There could be a few causes for the reverb hum; possible faulty cables or dirty connections could be one. I would suggest cleaning the RCA plugs and jacks on each end of both cables. Remove each plug (one at a time so there’s no chance of the connections becoming reversed) and spray a little contact cleaner/lubricant into and on the RCA jack. Re-insert the RCA plug into the jack a few times with a slight rotating movement each time if you can; this helps assure full surface contact. Do this to each of the four RCA connections and then give the amp a try.
If that didn’t help, it could be that the cables are faulty. Check the length of the cables, find yourself a replacement set and give those a try. Remember, as you remove the cables, be sure to follow the cables and mark the connections on each end of one cable so that there’s no confusion when you install the new ones. If the cables didn’t solve the problem, another cause may be the orientation of the reverb tank itself. Who knows how many times or in what way this amp has been serviced in the last 35 years? Someone may have installed/reinstalled the reverb tank incorrectly.
Check the location of the “in” and “out” jacks. Normally (at least in transformerdriven reverb circuits like this) the “in” jack should be the one closest to the AC mains transformer on the chassis (generally the transformer closest to the AC line input). This is because the mains transformer can induce hum into the reverb tank transformers. The reverb tank “in” transformer, being a much lower impedance transformer than the “out” transformer, is far less susceptible to this hum. If the tank is incorrectly positioned, simply turn it around and re-mount it.
There is one more issue we can explore that may help. You mentioned that the amp “does have the standard buzz when I take my hands off the neck.” You might want to have a 3-conductor line cord installed on the amp to make sure that the chassis has a good ground connection. It’s generally safe, effective, and cures most forms of “shock therapy.” If all that doesn’t take care of the reverb hum, then it just may be a design issue that you’ll have to live with.
Now let’s look at the tone issue. You mentioned that you replaced the output tubes, but you never made mention of having them biased. Under-biased tubes can sound muddy on the low end when pushed, so I’d definitely have that checked by a tech when you have the 3-conductor line cord installed. Next, have you checked to see if it’s the pedal itself that has the muddy low end? It’s entirely possible that the pedal lacks the low end definition that you’re looking for. I would suggest trying a myriad of different pedals to find one that suits your needs. I mean, you are a guitar player! Our quest is never over!
You might even try something like a cool old pedal called the Dallas Rangemaster – it was the secret weapon of many a ‘60s rock god. Basically known as a “treble booster,” it works by keeping the gain relatively unison on the lower notes and increasing the gain as the notes go up in frequency. This keeps the low end clean and tight while overdriving the amp in the upper registers. There are a few Rangemaster clones made today; check out the Java Boost by Robert Keeley and the Beano Boost by Analog Man. Just know that these units do not produce any form of distortion or overdrive, but simply drive the amps input stage into overdrive, so ya’ gotta play em’ loud and proud!

Milkman’s Jerry Garcia-style JG-40 combo.
Grateful Dead-inspired gear from Milkman and Scarlet Fire helps to keep the guitarist’s sound alive.
Guitar players wanting to catch the Grateful Dead’s particular lightning in a bottle exist along a spectrum. Some are content to take inspiration from Jerry Garcia’s playing but make their own way regarding guitar choice and signal path. Others strive to emulate Garcia’s sonic decisions down to the most minor details and create signal paths as close to Jerry’s as possible. In recent years, an ecosystem of gear has developed around fostering Jerry Garcia’s electric tone, including everything from guitars, amps, and stompboxes to on-board preamps and speakers.
Entire books about the Grateful Dead’s gear have been written, so we can’t cover it all here. Garcia tinkered with all facets of his sound from about 1971 until 1978, when his signal path reached stability. By then, his On-Board Effects Loop—an innovation he developed to control how much signal reached his effects—was dialed in, his backline firm, and his choice of effects pedals solidified. Even then, adjustments were made, especially when MIDI arrived or when technology like in-ear monitoring was used. Here are some basics.
Scarlet Fire’s recreation of Garcia’s Wolf, originally built by Doug Irwin.
It starts with guitars. For players wanting to get their Jerry on, there’s a wide range of Garcia-esque instruments—with just as wide a range of prices—out there. Recreations of the Doug Irwin guitars and the Fender Alligator Strat abound. China-built models from companies likePhred Instruments can go for as little as $700 or so. Luthier Thomas Lieber apprenticed with Irwin long ago, and his Lieber Guitars will deliver a copy of a variety of Garcia models. Leo Elliott’sScarlet Fire Guitars out of Dallas, Texas, takes things in another direction. Elliott builds Doug Irwin replicas that start at $20,000 and go up from there, with a current wait time of about 18 months for an instrument. He’s outfitted many of the top Garcia guitarists today, including Tom Hamilton Jr. and Jeff Mattson. Elliott says, “I’m a self-taught luthier; I didn’t really build my first guitar until 2010. I understood a little bit about woodworking before I got started, but I learned by reading books and through trial and error. I started building replicas of Doug Irwin’s Wolf guitar right away, which is sort of like building a car and starting with a Ferrari. I didn’t know any better. Then, eventually I got to know Doug Irwin and collaborated with him. So, I got to hold Garcia’s Tiger guitar and get to know it really well, and by 2015, I had built replicas of that guitar. There’s one guy who helps me around the shop, but otherwise, I am building these guitars on my own. I’m collaborating with Doug Irwin on a new series of Tiger guitars, which will retail for 50 grand each.” That’s one way to get your Jerry going.
The JBL-inspired Milkman K-120.
Garcia’s choice of amplifiers is another matter. He preferred Fender Twin Reverbs loaded with JBL Alnico speakers, which were popular amongst many rock bands in the 1970s. The details get complicated; Garcia’s amps were heavily modified, and the Fender Twin served as a preamp that ran to a McIntosh MC-3500 power amp.
It’s hard to find vintage JBL speakers today—at least ones in good shape. San Francisco’s Milkman Sound, founded by Tim Marcus, has created a faithful reproduction of those classic JBLsthey call the K-140. They’re coupling those speakers with a Garcia-style recreation of his Fender Twin that Marcus named the JG-40. “I think 75 percent of Jerry’s tone is in the JBL speakers,” Milkman’s founder says. “But when you start to analyze the other 25 percent, you kind of have to start withDon Rich. [Editor’s Note: Rich was the guitar player in Buck Owens’ band, pioneers of the Bakersfield Sound.] That’s Jerry’s tone, too, but the difference is Garcia’s midrange was a bit throatier. It sounds clean, but really, it’s not clean at the same time. Especially his tone in the late ’70s. There is something about running that Fender Twin Reverb through the McIntosh that would just completely blow out the tone in a really interesting way.”
Garcia colored his tone with off-the-shelf effects. This was, after all, long before the days of boutique pedals. By 1978 and beyond, you’d hear him playing through an MXR Distortion+, an MXR Analog Delay, and an MXR Phase 100. He often used auto wahs, preferring the Musitronics Mu-Tron envelope filter as well as a Mu-Tron Octave Divider and a Mu-Tron combination volume and wah pedal.
When I asked Jeff Mattson, Bella Rayne, and Tom Hamilton Jr. exactly how orthodox they are about using the kind of gear that Garcia did, I got three different answers.
Mattson tells me that because Dark Star Orchestra is doing something very specific, he really has to tailor his sound as carefully to Garcia’s as he can. “Some folks get too hung up on small things, like what kind of cable to use and things like that, and I don’t go that far. But it’s important for Dark Star Orchestra to get Jerry’s sound right because we are covering different eras and different shows. In 2022, for example, we went to Europe and recreated shows from the Dead’s famous Europe ’72 tour, so you have to pay close attention to what kind of gear they were using to do that right.”
Hamilton works differently. He’s always preferred a higher-gain signal than Garcia ever did, landing in more of a British or heavy metal tone. (Randy Rhoads was a big influence.) “I’ve always approached it like, ‘What’s the new information we can put into this thing?’” he says. “Not just recreate but pushing in a forward direction. And anytime I’ve played with the guys who played with Garcia back in the day, they always said to me, ‘You’re here because you’re here. Don’t try and do what we did back in 1978 or do it because Garcia did it that way.’ They’ve always encouraged me to be myself.”
Bella Rayne is just wrapping her head around what it really means to try to sound like Garcia. “Besides Jerry, I’m influenced by guitarists like Dickey Betts and Derek Trucks, so my tone tends to be a bit heavier and bluesy,” she explains. “I’m generally running a Stratocaster through a Fender Twin Reverb. But recently, I was doing a show, and a buddy of mine set up a Jerry rig for me, and that was so cool: JBL speakers, McIntosh head, the whole setup. I had never played through one. I didn’t know what the hype was all about. I plugged in, and it was just amazing; there was such a snap, and I was really commanding the band. I can see myself keeping my current rig but adding a Dead-rig to experiment. But honestly, anything is fine; I am not picky. I just want to play the best that I can.”
Brent Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ’90s country superstars. So, whether you know it or not, you’ve likely heard Mason’s playing.
Professional transcriber Levi Clay has done the deepest of dives into Brent Mason’s hotshot licks. At one point, he undertook the massive project of transcribing and sharing one of Mason’s solos every day for 85 or so days. Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ’90s country superstars. So, whether you know it or not, you’ve likely heard Mason’s playing. Levi shares the insight he gleaned from digging deep, and he tells us what it was like when they shared a stage last year. Plus, Levi plays us some great examples of Mason’s playing.
