Independent shopping perspective

The Korena take

A 40-watt, 8-inch combo for amplified acoustic guitar, with a mic channel, reverb and a DI. For players who need the pickup reproduced accurately in small rooms.

Product studyAER Alpha 40W 1x8 Acoustic Guitar Combo Amp Black

Strong match

Who this is for

  • Solo acoustic gigs in cafes and small rooms, guitar plus vocal
  • Studio work: DI to the interface, amp as the monitor
  • Players who want a flat, uncolored reproduction of their pickup

Consider the trade-offs

When to look elsewhere

  • Electric players chasing overdrive — this stays clean by design
  • Competing with a loud drummer on 40 watts and one 8-inch driver
  • Anyone needing two mic channels; there is one XLR

What matters in use

The specifications, translated

Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01

40 watts into 4 ohms

Enough for cafes, rehearsal and small rooms. Past that, the DI to the PA is the plan, not more volume.

Detail 02

8-inch twin-cone speaker, 60Hz-18kHz

The second cone carries the top end, so string detail and pick attack stay present instead of muffled.

Detail 03

Bass +/-8dB at 100Hz, mid +/-3dB at 550Hz, treble +/-11dB at 10kHz

Wide treble swing to tame piezo fizz. The mid control is deliberately gentle — it shapes, it does not scoop.

Detail 04

Voice filter at 300Hz on the mic input

Cuts proximity boom when you sing close in, so vocals sit above the guitar instead of fighting it.

Detail 05

DI output at -20dBV, line out at 0dBV

Feed the house desk direct and keep the combo as your own stage monitor.

Detail 06

Just over 14 pounds, roughly 10 x 10 x 9 inches

One-hand carry. Fits a car footwell or sits on a chair beside you instead of on the floor.

Final check

Know before you order

  1. 01Check the mains version matches your region — 110V and 220-240V builds exist.
  2. 02Reverb is the only onboard effect; use the send and return for anything more.
  3. 03Budget for a padded cover — 12mm birch plywood with a painted finish scuffs.

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01Can I plug a microphone into it?

Yes. Input one is an XLR combi, balanced at 600 ohms, with a 300Hz voice filter to cut low-end boom when you work the mic closely.

02Does it have a DI output for the PA?

Yes — a DI at -20dBV plus a line out at 0dBV. The house desk gets a clean feed while the amp stays your monitor.

03Is 40 watts enough to gig with?

For solo acoustic work in cafes, restaurants and small rooms, yes; the speaker is 96dB efficient. For bigger rooms, run the DI into the PA.

04Can I run my pedals through it?

Yes. There is a send at -10dBV and an effects return on input two at -10dBV/10k. The footswitch jack switches the internal effect on the tip, an external one on the ring.
