If using the BA6110 changing R155 to 100k will give the same performance as a tb-303. | If using the BA6110 changing R155 to 100k will give the same performance as a tb-303. | ||
There will still be some distortion with higher settings of volume and accent - the tb-303 does it too. | There will still be some distortion with higher settings of volume and accent - the tb-303 does it too. | ||
