Re: Lovepedal - Purple Plexi 800 [goop-alarm] [traced]

could someone advice how i could keep and prevent the MAX gain but make the pedal start from 0 gain setting from a lower amount of gain ?

thanks Mike

Re: Lovepedal - Purple Plexi 800 [goop-alarm] [traced]

If you are wanting more flexibility in the gain department. Try utilizing negative feedback. It would probably work better this mean to do what in the circuit , could you explain , if i use a 2k gain pot this will make any deference? or if i change the 470R ressistor to smaller or bigger this will ...

Re: Lovepedal - Purple Plexi 800 [goop-alarm] [traced]

i just measure the pot's ressistance when the pedal start to make the squeel , my multimeter show me in one of my builds 128 ohm and at another 48 so i placed in both pedals 150 ohms at the first and 50 ohm at the second at Gain pot pin 3 before to wire to the Pcb and the squeel stoped :) i do not t...

yes put a 150 ohm ressistor between the Gain 3 pin and the wire which goes to the pcb point.
