Players have come to expect a great clean sound in every Mesa Boogie amp, and the Stiletto Ace delivers in spades. Cleans like you've never heard before from an EL34 amp. Chiming transparent clarity riding atop warm breathing lows, and all this 3D magic is delivered with stunning dynamic attack.

Because classic English Rock sounds are neither totally clean nor inherently high gain, we've fitted duplicate Crunch modes in both Channels 1 and 2. For the player who has no use for pristine clean, this mid gain mode roams the wooly landscape from nearly clean to a punchy snarling breakup.

Just before these classic sounds end, Channel 2 begins its journey into high gain realms no British amp ever dared. Tite Gain blisters with searing heat while maintaining articulate focus. Fluid Drive bumps the gain and liquefies the attack to inspire your single note soloing to a new level of freedom.

Combining this more aggressive preamp with the brighter, faster feel of the Ace's 50 watt power, creates a Stiletto that cuts with more depth and finesse than any of its English counterparts. Even veteran tone snobs need to check this Mesa Boogie amp.

Mesa has also included a patented Switchable Rectifier feature in this tube amp that allows you to tune the power supply for the feeling that best suits your style—Tube for a vintage-inspired sag or Silicon Diodes for tight tracking punch and authority.

With shocking low end that's tight and percussive, the Mesa Boogie Stiletto Ace guitar amp rules. Crunch you'd swear is coming from a 4x12, with top-end openness that blooms and enhances clean sounds, the Ace may be the ultimate combo… redefining portable EL34 Tone.

Each Channel contains 3 Modes:

Channel 1 focuses on rhythm sounds with the big warmth of Fat Clean or the urgent attack of Tite Clean, while Crunch hits hard with mid-gain for the ultimate British chording sound.

Channel 2 starts with a duplicate of Channel 1 Crunch—selecting Tube Rectification here creates an awesome solo sound. An infusion of tube juice creates the blistering high-gain focus of Tite Gain and another shot unleashes the liquid soul of Fluid Drive.

A patented Switchable Rectifier feature enables you to select the type of rectification for each channel. Use the tight-tracking punch of the Diode setting for maximum headroom in either Clean mode or more aggression in Crunch and use the elastic sag of Tube for ultimate expression in Tite Gain or Fluid Drive for lead sounds.

Bold/Spongy Power located on the main AC Power switch provides a reduced line voltage setting for additional power sag and enhanced top end harmonic content.

Front Panel location allows on-the-fly selection of incoming line voltage with the full 117 volts for headroom and authority or a reduced voltage setting (like a built-in Variac) for a vintage-inspired brown vibe.

Guitar Amplifier

By Greg Mullins

from Melbourne,Australia

A friend of mine has recently bought a Stilleto I plugged my Les Paul into it the other night and was blown away by the tone and the variation of sound from metal to blues,jazz or subtle country no matter what type of guitar you own Boogie Amps will enhance it I'm a proud owner of Mesa/Boogie Rectoverb 50 so I know from my own experience how amazing these amps really are I tell my guitar students that if you buy a Mesa/Boogie you'll still be using it 50 years from now.

Mesa Boogie Stiletto Ace 50W 2x12

By Scott

from Tampa, FL

I had tried out about 7 different amps over the last several months and this was one of them. This amp does metal pretty good but could use a boost/overdrive pedal for leads. Amp sounded good for the most part but quite honestly, after playing a Bogner Alchemist, nothing sounds as good. I know what I just said my sound sac-religious to many but I'm telling you, the Bogner is much better. The cleans on this amp is decent which with EL 34s as the power tubes, you can see why. Its built like a tank, very good manual, cover, casters. Sound is good, but not great. I traded mine for an ALchemist and am very, very happy.
