JOYO AC20 20W - Compact Amplifier for Acoustic Guitar
The JOYO AC-20 has been designed with tonal characteristics specifically enhancing acoustic guitar sounds. Featuring a natural sounding three band EQ, the amp produces sparkly highs and detailed mids without too much low-end "woof-y-ness", perfect for amplifying your acoustic guitar without too much electric "twang".  With 20W of power, delay, chorus and reverb effects and additional mic and auxiliary inputs, the AC-20 is excellent for practice sessions and even small live shows.

3 Independently Controllable DSP effects: Chorus, Delay and Reverb
The guitar section of the AC-20 features 3 built-in DSP effects: Chorus, Delay and Reverb, all of which can be used simultaneously - such flexibility is rare among similar amplifiers. Dial in the right combination of these effects to get get great pop, rock and jazz sounds acoustic sounds. 

Microphone Channel
The amp also features dynamic microphone amplification channel giving you a defined and present vocal sound. This channel also features a reverb to help blend vocal and guitar sounds and add space and texture. 

Auxiliary Input
Any great acoustic amp needs an AUX input and so does the AC-20. Connect your phone, MP3, or CD Player and play along to backing tracks for practice or performance. 

An Important Note from the Supplier
While JOYO's range of AC amplifiers has proven to be a popular item among the Australian and international markets, stock has been received with an unfortunately high noise floor. JOYO have assured us that this is well within their accepted signal to noise ratio, and SWAMP have extensively tested the range to confirm that no noise can be heard when performing, playing back music, or just jamming through the mic and guitar channels. No controls on the AC amplifiers will increase the noise, and it is not present when audio is passing through the speaker. When the amplifier is switched on, a "whoosh" or "hiss" may be heard, though we have been assured by JOYO that this is normal performance for the AC amplifier range.
