The past several years have brought about an era of reinvigoration for vintage non-master volume style amplifiers and I believe some of the reason is due to the fact that there are some great choices for attenuators out on the market today. Everyone knows that there is nothing that can harmonically compare to the tone of a quality vintage tube amp cranked up with its warm power tube distortion running along with its preamp gain. But the trick has been trying to capture that great tone at lower volumes and that’s where an attenuator can come in very handy.

Fender 59 Bassman LTD
The Fender Bassman evolved as an amplifier designed to initially go along with the Fender Precision Bass. It’s perhaps a bit of an irony that this amp design is among the most revered from guitarists – not bass players. Add to this the fact that the first Marshall amplifiers were largely leveraged from the Bassman’s circuit design (which in turn spawned a countless array of further clones as time passed), and it’s easy to understand why the Fender Bassman was the first amplifier chosen as a tweed reissue in the early ‘90s.
Marshall Hand-wired Reissue 18 Watt Combo and 20 Watt Head/Cabinet
Introduction
Marshall’s long-awaited handwired series reissue amplifiers are finally here with the debut of the company’s 1974X model 18-watt combo and 2061X model 20-watt head with 2061CX cabinet. These first reissue models are based on the originals produced in the ‘60s and ‘70s and Marshall has assured us that every attention to detail has been made. And these are not limited-edition reissues, but are part of Marshall’s regular production lineup!
Even the included manuals proudly cover the story of the many detailed aspects of the design and development. From the cosmetic finish to the construction details of the transformers and customized speakers, it is clear that Marshall team set out on a mission to create the ultimate reissues.

THD Electronics Flexi 50 Amp Head
"Wait a minute, this amp isn’t a clone of a plexi Marshall?!"
That was my initial thought when plugging into this amp for the very first time. And that’s actually a good thing for many users who will enjoy the added flexibility of the many tonal options presented by THD Electronic’s new Flexi 50 amplifier. Though my initial idea really was to pit a ’68 50 watt Marshall against the THD Flexi-50 amplifier head, it was clear from both looking at and listening to the Flexi-50 that this would have been an apples to oranges type of comparison. The Flexi-50 offers quite a bit of tonal and feature-set variety and it would be inappropriate to simply compare it to one single amplifier.
Perhaps I subconsciously took the name "Flexi" and associated it mostly with a 1960’s plexi-era Marshall. In any case, Andy Marshall, THD’s President explained it best: "It’s named the Flexi-50 because of its flexibility in being able to capture vintage British and American tones."

Mojave Ampworks Scorpion 50 Watt Amplifier Head
Mojave Ampworks impressed us last year with its Peacemaker, a powerhouse of an amp head running EL34s in its power section and providing tones that aim to please a range of rock guitarists. With its 100 watts of output, the Peacemaker was designed for, and best used in, a full-band environment, and preferably those with loud drummers – otherwise consider an attenuator a "must have" device when wanting to get the most out of the Peacemaker.

Metropoulos Amplification ’68 12000-Series Plexi 100 Watt head
Introduction
"I want an amp that can nail the early Van Halen tone 100% but I don’t have $5,000+ (at the time of this writing – 11/05) for an original Marshall ’67-’68 era plexi." This is what many of you have written to us and asked for in the past. "What should I use?"
Some of you have even had more demanding requirements for your amplifier citing that in addition to the Van Halen tone, you ALSO wanted the ability for the amp to respond and produce tones as diverse as Cream, Jimi Hendrix, Led Zeppelin, and AC/DC, among others.

Celestion Heritage Series G12M and G12H “Greenbacks”
Chances are if you ask a player who uses vintage Marshall amplifiers to name their favorite speaker, they’ll either call out the G12M or G12H “Pre-Rola Greenback” speaker. These two speakers literally defined the sound of rock since the 1960’s and have continued to do so ever since.

Mercury Magnetics Epiphone Valve Junior Mod
The Epiphone Valve Junior is a small 5W amp head that is first most noteworthy because it is, well, cheap. Especially considering it is a tube amplifier, selling for $129 is frankly a bargain. Because of its simplicity and price, it has had a bit of an underground following being a pure-tube circuit with a single 12AX7 in the preamp stage and an EL84 as its output tube running Class A. The amp has 4,8, and 16 ohm output jacks to enable a wide use of cabinets.

This is the claim made by George Metropoulos at Metropoulos Amplification. In my case, I was in search of a replica point-to-point circuit board for my Marshall JTM-45 reissue. Did MetroAmp.com deliver? Not only did MetroAmp.com deliver; they gave me the product and information to help complete my quest for a vintage Marshall JTM-45.

All About Ohms
Electrical resistance within speakers, amplifiers, as well as all basic electrical connections, is expressed in ohms, named after George Simon Ohm, a German physicist. While we needn’t go into the background of him and his achievements, or even the heavy details about resistance, ohms, or impedance, this is an area that is often confusing to people. The following is a primer all about ohms and how it relates to speakers and amplifiers. My hope is that very simply, any confusion on the topic will be eliminated.
