The foam cover over the metal grill has been removed as with all AER combos , its perishes and looks scruffy!  also gets inside the grill so is messy as well, best to remove it, it adds nothing to the acoustics, purely cosmetic. 
Highly connectable & durable
The Alpha has one channel, but two independent input stages (line and mic/line) which offers you various options when it comes to signal processing. This AER amplifier is also subtly dynamically controlled, ensuring absolute reliability in full load operation despite its smaller size and weight.
On the amp’s front side, you’ll find a combo socket signal input for a 6.3mm mono jack plug and XLR connectors (48V phantom power) and a signal source selector switch which allows you to choose between line for instruments and other line level sources or mic for microphones – there is also a rotary gain control on this input level.
The second input section consists of a 6.3mm mono jack plug and an input sensitivity switch. There is also an LED overload indicator, tone colour filter activation switch and gain control. Along the rest of the front panel you’ll find the bass, middle and treble controls, the efx level or reverb control, the power on/off switch and master level control.
The rear panel houses the line out, supplying the preamp signal taken after tone control, effects and master for forwarding to your other devices. The send output allows the connection of an external effect device and in conjunction with the return input forms a loop designed as external loop. A headphone out enables the connection of stereo headphones when you need to ply silently, without disturbing the neighbours.
Find your perfect sound
Featuring 40 watts of power and an 8” twin cone speaker system, this amp provides a balanced tone at all sound pressure levels. The triple-band equalizer of the Alpha provides an active and high-quality sound interaction tool that supports the natural tone of an instrument’s voice, whilst simultaneously offering the possibility of a controlled accentuation. With all controls in mid position, the amp will give you a pleasing natural sound, which can be broadened using the colour filter. This has the effect of lowering the mids and lifting the trebles, producing a more open and light tone – especially well-suited to fingerpicking techniques.
