The great Wampler Mods uses a A1M and 1k to increase the gain from 46dB (original) to 60dB (which is too much for my little 15w amp). The filter is made for the 1k and 220n, this way the 720 Hz is manteined in the high pass filter (original is made by 4.7k and 47n). So here you´ve got some values for using diferent potentiometers values keeping the cut at 720 Hz:<br /><br />1meg = 60 dB<br />500k = 54 db<br />250k = 48 dB <br /><br />The 250k potentiometer is more likely to the original in lt spice frecuency renponse graph, much more with 1.5k and 150n instead 4.7k and 47n.<br /><br />For me.. ...A500K pot/1k Resistor/220n Cap, sounds the best in my amp.<br /><br /><br />Saludos desde VenezuelaPercy Hornickelhttps://www.blogger.com/profile/10941035617287446189noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-47429225620972913982019-08-31T15:56:18.144-04:002019-08-31T15:56:18.144-04:00Oh man, I'm just now noticing the typos.
