But i have a question, when the pedal is active and no strings pulled from the bass , there is a high pitched noise like " a banshee"( i dont know how i can describe, haha). This is normal and how could I reduce or eliminate it? (Looks like begins from the Q3 (C)ollector and is greater in Q4 (C)ollector)<br />Thanks USBhttps://www.blogger.com/profile/18367562663038231316noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-51388888609575854512023-05-06T14:21:41.092-04:002023-05-06T14:21:41.092-04:00Additional note:
