Product Overview

Alphanso Rock 52 is designed from the modern integrated circuitry. It’s a solid-state semiconductor amplifier. This one is able to handle 3 input signals at a time (two mono and one stereo). 52 watt is good enough for home practice with electric guitars or acoustic guitars or even mic, keyboard, electric drums, etc. Inside this combo amp, 2 x 6 inch speakers have been mounted and that could reveal your guitar tone effortlessly. Your guitar tone would be very bassy and clear treble. Rock 52 amp has its own built-in overdrive effect with gain control; delay control, dedicated mic pre-amp, 3 band tone control that responses upto ±12dB, 2 stereo channels, and 30 watt external speaker out.


 ① 1⁄4 inch Mono TRS Jack input. A maximum of 3m/10ft instrument cable needs to be used. Always use a low noise high quality cable to avoid unexpected hum. Gain control works in both clean and overdrive channels. The clean/OD switch is the clean or overdrive tone selection switch. The clean level is the volume control of the clean pre-amp channel and the OD level is for overdrive channel’s volume.

 The delay control works on the guitar and mic channel. You can easily bypass this effect just by the on/off switch. Time knob controls how long it would take to repeat the sound (4ms to 720ms). And feedback knob controls how many times the sound would feed into the signal; max 8 times.
    N.B. This is not reverb but delay. Reverberation and delay are two methods of signal processing that are often incorrectly equated. The confusion comes from the fact that they are so closely related. Reverb and delay aren’t completely unrelated effects — reverb can be thought of as a network of many short delays.

 ③ Mic input channel is for any kind of acoustic sound or balanced sound. A dedicated gain control and a tone control are present here. It can be shaped before dive into the equalizer because when multiple instruments would be played at a time sound shaping is very important.
    N.B. Mic pre-amps are very much diverse than the guitar pre-amp. Its frequency response is much lower than the guitar input.

 ④ 3 band equalizer control. It is an active equalize, so the response is huge. It is not suggested using its maximum power. The equalizer responses over ±12dB bass, ±10dB mid, and ±12dB treble. Follow the user manual’s recommendations. The on/off switch allows you to bypass the equalizer completely.

 ⑤ Rock 52 has 2 x 3.5mm stereo channels. The left one can handle upto 1dBV (stereo) auxiliary input. The volume of auxiliary input needs to control from the source. The right one delivers sound to headphones or recording input and can deliver upto 450mW to 45Ω load.

  This is the master volume that controls the main power amplifier’s sound, which means it works for the speaker only. It won’t effect on headphone output. N.B. pre-amp volume level should be as same as the master volume.

Additional information:
