Introduction The AS50D is a compact and portable 50 Watt combo amplifier specially designed for use with acoustic instruments. Between its two channels, this combo has the flexibility to handle instruments with transducers, such as piezo or magnetic pick-ups (channel 1), or microphone for either vocal or instrument reproduction (channel 2).
Note: When using the Chorus, higher speed settings usually sound better with lower depth settings and vice versa. Experiment to find which selection suits you best. 18. Frequency Control If feedback occurs when the Master Volume is set to the desired performance level, select the switch (item 17) and rotate this control until the offending frequency is eliminated. 14. Reverb Balance Control 19.
