Alphanso Rock-22 Solid-State Guitar Amplifier

Take your home practice sessions, small-group rehearsals, and studio recording sets to the next level with the Alphanso Rock-22 Guitar Amplifier. Engineered utilizing upgraded integrated circuitry, this powerful solid-state combo amp balances robust wattage with sharp note definition, rich onboard analog-voiced effects, and flexible dual-input mixing capabilities.

Perfect for players who need more headroom and acoustic projection than a standard bedroom desktop amp, the Rock-22 offers a highly scannable, user-friendly control layout that extracts maximum clarity and punch from both electric and acoustic guitars. Its durable cabinet construction with an optimized semi-open back profile ensures rich low-end resonance while remaining highly portable for musicians on the move.

Product Highlights

• Upgraded Wattage and Headroom: Powered by a highly efficient, clean solid-state semiconductor layout pushing plenty of stage-ready pre-amp capability. This gives you extra dynamic headroom, allowing your clean notes to stay pristine at higher volumes.

• Custom Mid-Range Speaker: Houses an enlarged, heavy-duty customized mid-range speaker driver. It effortlessly reveals the natural acoustic voice of your instrument with precise top-end clarity and tight, punchy bass response.

• Dual-Channel Multi-Signal Mixer: Capable of handling two input signals simultaneously (one mono guitar jack and one stereo auxiliary jack). This setup enables you to effortlessly blend backing tracks or metronomes with your live playing.

• Built-In Overdrive Matrix: Features a dedicated, switchable clean/overdrive toggle switch paired with an independent pre-amp Gain pot. Easily shift from glassy, transparent jazz textures to aggressive hard-rock crunch and high-gain clipping.

• Integrated Time-Based Delay: Upgraded with a built-in analogue-voiced Delay engine running from 4ms to 720ms with up to 8 feedback repeats. It can be bypassed entirely with an explicit on/off switch to keep your signal path completely dry when needed.

• Active Single-Band Shape Equalizer: Utilizes an ultra-responsive, active single-band Tone filter that delivers an extensive range of up to $\pm12\text{ dB}$ across treble and bass responses, allowing for deep tonal sculpting.

Specifications

Physical I/O and On-Panel Control Matrix

• 1/4-Inch Mono TRS Input: Dedicated front-panel connection optimized for high-quality, low-noise instrument cables to eliminate unexpected system hum and interference.

• Gain & Clean/OD Toggle Switch: The Gain control dials in your input clipping pre-amp levels across both active channels. Use the mechanical switch to swap between pristine clean textures and driven clipping tones.

• Pre-Amp Volume Level: Sets the output floor of your pre-amplifier stage before sending the signal to the master block. For optimal fidelity, align this closely with the Master volume.

• Delay Knob & FX Switch: Manages time-stamped repeats on the guitar channel exclusively. A physical bypass toggle lets you drop the time-based reflections instantly out of your mix.

• Single-Band Active Tone Knob: Dictates overall frequency brightness or warmth. Turning past noon boosts the upper-mid bite, while turning it counter-clockwise rounds off the high-end response.

• 3.5mm AUX Stereo Input: Allows quick routing for tablets, smartphones, or computers to inject high-fidelity backing tracks directly into the amplifier mixing circuit (volume managed via the source device).

• 3.5mm Headphone / Rec Out: Automatically routes output for silent midnight practice sessions or links directly into a desktop audio interface recording channel.

• Master Volume: Controls the final output level sent directly to the internal driver. Adjusting this knob has zero effect on the headphones output line, protecting your hearing during quiet practice sessions.

Why Choose the Alphanso Rock-22?

The Alphanso Rock-22 represents an incredible performance upgrade for players looking for more power, depth, and volume flexibility without jumping up to an expensive, over-encumbered gigging stack. Where most traditional entry-to-intermediate amplifiers only offer a standard clean channel, requiring you to invest heavily in external distortion and delay pedals, the Rock-22 comes equipped with an adjustable analog-style delay and an aggressive built-in overdrive circuit right out of the box.

Its smart dual-channel input design allows you to jam along with your favorite tracks without needing a separate sound system. Backed by an active $\pm12\text{ dB}$ equalizer, heavy-duty black corner guards, and separate headphone and master volume controls, this amp delivers excellent flexibility and reliable solid-state performance for everyday practicing and recording.
