Available at Kitarshokak, this power amp is a rare piece to come across. You’ll get wide dynamic range and a tone full of nuance with no compromises. There are no exact production information, but it’s believed that around 1,000 units were made.

It has been part of professional rigs used by well-known musicians:

• Kirk Hammett
• Billy Corgan
• Prince
• Andreas Kisser
• John Sykes
• Jeff Irwin

 

This particular unit also belonged to Soziedad Alkoholika, and it’s loaded with 4 x Svetlana 6550 power tubes!

• Total power: approx. 500W (≈ 200–250W per channel)
• Configuration: Stereo / Dual Mono
• Power tubes: 8 x 6L6 GC Mesa Boogie STR 440 + 4 x 6550 Svetlana
• Phase inverter tubes: 4 x 12AX7 Mesa Boogie

Sound character

The Strategy 500 doesn’t just sound “good”… it sounds big.

• Tight and deep low end
• Defined mids that project in the mix
• Clear highs without harshness
• Fast, punchy attack
• Maintains definition even at extreme volumes

Designed for big, nuanced tones and demanding productions.

Why it matters

Many modern systems rely on lightweight power amps or digital modeling, but the Strategy 500 offers the opposite:

Real power, real feel, real inspiration. That’s why it remains highly sought after today.

Ideal for

• Rack rigs with preamps (Triaxis, Studio Preamp, JMP-1, etc.)
• Guitarists looking for huge, defined clean tones
• Metal / rock where punch and clarity at high volume are essential
• Professional studios aiming to capture real tube power
