Metropoulos debuts the 100-watt DVL-1

New plexi-styled amp developed with Alice In Chains’ William DuVall

The Metropoulos DVL-1 utilizes an all-tube EL-34 two-channel, four-mode design. Each of the four modes is named for the year of Plexi-fueled rock awesomeness that it sonically represents. The brand new amplifier is the culmination of more than a decade of friendship between William DuVall of Alice In Chains and ampsmith George Metropoulos. The mission was simple: build the ultimate plexi-style 100-watt amplifier with maximum flexibility and functionality and zero compromise in components, signal purity, and tone.

Channel One houses the DVL-1’s ’65 Mode and ’66 Mode. According to the builder, the ’65 Mode nails the “maximum R&B” tones of 1965-era Pete Townshend up to the full-throated JTM-45 growl of AC/DC’s Angus Young. The ’66 Mode gets us into the glorious heavier blues-rock tones of Cream and The Jimi Hendrix Experience.

Channel Two houses the DVL-1’s ’68 Mode and Mod Mode. The ’68 Mode is inspired by the 1968 Marshall plexi amp used by Eddie Van Halen on the first six Van Halen albums and tours. Builders have tried to capture Eddie’s ‘brown sound’ through various devices over the years. Metropoulos went a step further, acquiring a 1968 100-watt Marshall plexi amp from the exact same production series and built from the exact same parts as Eddie’s magic Marshall (right down to the very close serial number). The DVL-1 captures the same sonic voodoo. The Mod Mode starts where the ’68 Mode ends, jacking things up with even more gain and low-end “thunk.” Think Metallica or Alice in Chains. Mod Mode offers maximum heaviness but with a clarity, musicality, and harmonic richness often missing from other super high-gain amplifiers.

In addition, the DVL-1 also has a MidBoost for those occasions when you just need a little extra kick within that frequency range. The DVL-1’s Mid Boost is very musical without a hint of harshness. William DuVall hand-picked the capacitor himself at George’s workspace in Detroit. It’s just enough to give certain lines or fills within a song the extra cut they need without being overwhelming.

The DVL-1 is available for order through the Metropoulos website. The 100-watt amp head runs $3,799.


– Two separate channels, with independent gain and master volumes
– Channel A offers ’65 mode and ’66 mode
– Channel B offers ’68 mode and MOD mode
– All modes are accessible via the footswitch
– BOOST is a separate function, which can be applied to any mode. Think of it as a high voltage, clean boost in front of the amp. Just built in and with its own dedicated volume level control
– Foot-switchable Mid Boost, separate from the BOOST circuit and applies to all modes
– Variac mode simulates using a variac to operate a plexi at 90V AC
– Switchable for 50 or 100 watts output
