For at least a decade, the classic Ampeg SVT was the dominant bass amp for power and tone.
From the giant, hefty beasts of yore to their modern, ultra-portable equivalents, bass amps have come a long way. So, what's next?
Bassists are often quite well-informed about the details of their instruments, down to the finest technical specs. Many of us have had our share of intense discussions about the most minute differences between one instrument and another. (And sometimes those are interrupted by someone saying, "It's all in the fingers.") But right behind our backs, at the end of our output cables, there is a world of tone-shaping that we either simply ignore or just don't want to dive into too deeply. Turning a gear discussion from bass to amp is a perfect way to bring it to an abrupt end.
Since the beginning of our instrument's history, bassists have faced the fundamental and existential problem of trying to be heard. It's solved now, but too many players don't seem to be interested in how we got here. And it's not just bassists. Even some amp manufacturers haven't been concerned with the details. A few readers might remember that in my September 2019 column, I discussed class-D amp technology. As part of my research, I called a very respected amp manufacturer to get his insight into class-D technology. His stunning response was: "We simply checked some Asian-made modules and chose the one we thought sounded best, but I don't know and never cared how they work." Even the offer of a short technical introduction was met with blissful ignorance. So, if anyone thinks they don't need to know how their amp works, at least you're in good company!
Over the course of the last 80 years or so, the fundamental technology used in our amps has been replaced—and not just once. The technological changes came in several waves and another might be on the way.
Here we are now after this last wave of amp-tech: down from 300 watts at 40 kilograms or 88 pounds in the 1970s, to 500 to 1000 watts at 1 to 3 kilograms or 2 to 7 pounds today.
For the greater part of the last century, bass amps relied on tube circuitry, and it took until the middle of the century to make decently powerful, but heavy and fragile, amps. Unfortunately, guitarists used the same technology—and sometimes even the amps that were initially made for us. (Remember that our low-end needs about 10 times the power of a guitar amp to cut through!) So, as their volume increased, our need for more power just became greater. Our problem remained until the 1960s when amps like Ampeg's B-15 Portaflex and SVT entered the scene. High-output amplification manufacturers sprouted everywhere, enabling loud rock bands to move from clubs to stadiums.
Though the transistor quietly altered the landscape of radios and small solid-state amps during the early 1950s, it took until the late '60s before this technology made it into our rigs. The first companies to make solid-state amps were those who possessed a higher engineering background. Vox, for example, released one of the first solid-state bass amps, thanks to their prior experiences with solid-state circuits from their organs. Many smaller companies soon followed, although most earned a reputation for unreliability. But the technology developed at a breathtaking pace.

During the 1980s, clean and powerful hi-fi-esque synth sounds became trendy. This benefitted bassists with the development of clever tone-shaping options, hybrid circuits with tube preamps, bi-amping, internal DIs, and even more power.
Once we were sure to be heard, it was time to look for other advantages, like reduced weight and size, and along came another wave of new amp technology: class D. (See my column "Signal Processing in Class-D Amps," September 2019.) The basic principle behind class-D technology is pulse width modulation (PWM), which sounds as if those with higher engineering skill would once again be in the lead. Instead, there are just a few manufacturers building class-D power modules, and amp builders can use those as the foundation of their own amps. Just get one of the modules, which come in different power ratings, add a power supply and a tone-shaping circuit, and you're done. With several competing manufacturers offering identical power amps, the individual strengths have fully shifted to the qualities of their tone-shaping circuitry and other add-ons or gimmicks.
Here we are now after this last wave of amp tech: down from 300 watts at 40 kilograms or 88 pounds in the 1970s, to 500 to 1000 watts at 1 to 3 kilograms or 2 to 7 pounds today. What could be the next move? It looks as if the power-to-weight ratio has reached an end for quite some time, but tone-shaping capabilities in preamps might shift from classic circuitry to profiling or modeling amps as a fourth wave. And this time it's clearly engineering competence that will make the difference. Can you imagine what instruments we'd be playing today if our basses had made similar progress?

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.Watch the official video documenting the sold-out event at House of Blues in Anaheim. Join Paul Reed Smith and special guests as they toast to quality and excellence in guitar craftsmanship.
PRS Guitars today released the official video documenting the full night of performances at their 40th Anniversary celebration, held January 24th in conjunction with the 2025 NAMM (The National Association of Music Merchants) Show. The sold-out, private event took place at House of Blues in Anaheim, California and featured performances by PRS artists Randy Bowland, Curt Chambers, David Grissom, Jon Jourdan, Howard Leese, Mark Lettieri Group, Herman Li, John Mayer, Orianthi, Tim Pierce, Noah Robertson, Shantaia, Philip Sayce, and Dany Villarreal, along with Paul Reed Smith and his Eightlock band.
“What a night! Big thanks to everyone who came out to support us: retailers, distributors, vendors, content creators, industry friends, and especially the artists. I loved every second. We are so pleased to share the whole night now on this video,” said Paul Reed Smith, Founder & Managing General Partner of PRS Guitars. “I couldn’t be more proud to still be here 40 years later.”
With nearly 1,400 of the who’s who in the musical instrument industry in attendance, the night ended with a thoughtful toast from PRS Signature Artist John Mayer, who reflected on 40 years of PRS Guitars and the quality that sets the brand apart. “The guitars are great. You can’t last 40 years if the guitars aren’t great,” said Mayer. “Many of you started hearing about PRS the same way I did, which is you would talk about PRS and someone would say ‘They’re too nice.’ What’s too nice for a guitar? What, you want that special vibe that only tuning every song can give you on stage? You want that grit just like your heroes … bad intonation? The product is incredible.”

Gamechanger Audio Auto Reverb
gamechangeraudio.com
When the first Moog synthesizer appeared, it freaked out a lot of musicians—not least for the way it blurred the divisions between instruments and their roles. Was it percussion? A keyboard? A reed instrument? Many effects makers build from this philosophical foundation. The Latvian company Gamechanger often seems to revel in it—an attitude that’s manifest in the company’s Auto Series pedals, which includes the Auto Reverb.
There’s no reason you can’t use the Auto Reverb in a very straightforward fashion. The plate, spring, and hall settings are all very nice digital representations of their analog inspirations—and I’d be perfectly happy playing an instrumental surf set with the spring mode, for instance. But because you can control the parameters like the reverb’s level, decay, tone, and the filter with changes in pitch and dynamics, the Auto Reverb can function in highly orchestral ways, transforming itself from subtle to outlandish as a musical piece shifts in intensity or rises from low to high keys toward a blurred, hyper-spacious climax. While these attributes make the Auto Reverb a great fit for prepared guitar and conceptual pieces—and invites many themes and compositional ideas within those forms—it can just as easily be configured to create an especially dynamic and dramatic pop song arrangement on stage or in the studio that might otherwise be relegated to automations within a DAW. It’s fun to use, if not always intuitive. But knowing its ways can expand your musical options significantly.
