Designed for electric guitar players who value variety in their tone, the Blackstar Silverline Stereo Deluxe is a 2x100W combo amplifier with two 12" Celestion VT-Type speakers. The combo amplifier aims to combine strides in analog and digital technologies to give you multiple classic tones.
With the Silverline Stereo Deluxe, you get the ability to store up to 128 presets, and access four of them at a time from the amplifier itself. The amp makes use of six preamplifier voices and six power amp emulations. Preamp voicings include Clean Warm, Clean Bright, Crunch, Super Crunch, OD 1, and OD 2 for a wide variety of tones.
The power amp section, on the other hand, makes use of SHARC powered DSP algorithms and Blackstar's TVP technology to give you the vibe, response, and tone of six notable, real-world power amp sections. When you combine the preamp and the power amp sections with Blackstar's ISF tone control, you'll find you have a fine hand on your tone.
Additionally, the Silverline Deluxe offers a panoply of studio-quality effects, operable in stereo on this unit. These effects include reverb, phaser, flanger, tremolo, delay, and more. You can control the level, tempo, and type of these effects from the amp itself.
Bass, mid, treble, gain, volume, and Blackstar's ISF tone controls are on hand. You'll also find resonance and presence controls for influencing the behavior of the power amp section. Secondary controls are available in the effects section. Press and hold the tap tempo button, and you can access Presence and Resonance controls, as well as a secondary effect control; this control changes depending on the type of effect.
In addition to the 1/4" input for electric guitars, the amplifier also sports a 1/4" emulated-speaker output. You can output sound directly, over USB, to your computer, using the guitar amp as an interface for your electric guitar. An FX Loop is available via the INSIDER app, which also gives you a deep dive into tones.
You'll also note the footswitch input, through which you can control multiple aspects of the pedal by means of a separately-available footswitch. It is also possible to control the amplifier via a MIDI connection. Should you wish to plug into external speakers, you'll find four 1/4" jacks for doing so, rated at different resistance values to accommodate all sorts of cabinets.
