Input Gain For the cleanest possible signal, adjust the Input Gain so that the Clip / Low Battery LED barely flickers with strong playing.

Compression (continued) To gently smooth out your instrument’s all-around response, set the Compression between 8:00 and 11:00. For more punch set the Compression between 1:00 and :00. This is especially effective for tumbao and walking bass styles. For heavy compression with lots of sustain set the Compression knob between :00 and 5:00 (for best r esults set the Input Gain as high as possible without lighting the red Clip light).

Turn up the amp some more until you get feedback around open D and below (deep-bass feedback). 5. Move the Depth control counter-clockwise until deep bass feedback goes away

Tone Controls Bass - We carefully voiced this control to give you the deep bass you need for your lowest notes, with plenty of mid-bass punch for the D and G strings. If the sound becomes boomy when you raise the Bass control, lower the Depth control until the sound tightens up. Low-mid - Boost here to thicken up the low end. Cut low mids for a more transparent tone or to reduce feedback with acoustic bass. Mid - This control subtly affects how well the instrument blends in or stands out in t
