The apex of Slash's lifelong pursuit of tone!

The Magnatone SL-100 Slash Signature is a 100-watt, British-voiced tube amp head developed alongside the legendary top-hatted musician himself.

Built to the Guns N' Roses guitarist's demanding specifications, the SL-100 takes Magnatone's Super Fifty-Nine M-80 (Slash's amp of choice on Guns N’ Roses’ 2023 world tour) and cranks it up to devastating new levels.

This hot-rodded tone monster slithers with muscular EL34-fueled textures via two footswitchable gain modes optimized for maximum clarity, grind, and headroom: all the important ingredients in Slash's sonic recipe.

Far more than a mere Appetite or SIR #39 clone, the SL-100 boasts an entirely new design. The result is a high-octane tube amp with a British voice and enough American rock 'n' roll attitude to fill a snakepit.

The SL-100 includes a Master volume knob, independent Lo and Hi Gain knobs, and a powerful 4-band tone stack for dialing-in everything from pushed cleans to hard rock crunch to searing leads.

You also get a tube-buffered FX loop for integrating your pedalboard.

The Magnatone SL-100 Slash Signature isn't limited to nailing the elusive Appetite tone, it's the culmination of one of rock's most esteemed guitarist's lifelong quest for tone!

Two footswitchable gain modes.

The Magnatone SL-100 Slash Signature sports two footswitchable gain modes, enabling you to tackle pushed cleans, muscular high-gain, and everything in between.

The amp's Lo gain mode is reminiscent of a 1960s-era British design, but with beefed-up lows and sweetened highs to make it suitable for modern playing styles.

Matching a humbucker-equipped axe with the SL-100's Lo mode enables you to clean up your tone using your guitar's volume knob, but with plenty of crunch at your disposal when you crank it.

You can also match a single-coil-equipped guitar with Lo mode for instant Jimi-isms.

The SL-100's Hi gain mode gives rise to the modded, cascaded-gain preamp sound that ruled the 1980s, but with added articulation and zero fizziness.

In fact, the Hi gain mode sounds so smooth that you can crank the SL-100's Treble control all you want for extra pick clarity without unwanted harshness!

Loaded with stage-worthy features.

The SL-100 brandishes a streamlined set of controls, making it a breeze to dial in.

For starters, you get an intuitive 4-band tone stack (Presence, Bass, Mid, and Treble knobs).

Independent Lo and Hi Gain knobs allow you to set different levels of grind for the amplifier's Lo and Hi gain modes.

The SL-100 also includes a tube-buffered FX loop optimized for pedal-level operation.

You also get a Master volume knob, so you can get all the crunch you want, even at bedroom levels!
