And to me, two separate gain controls are just waste of pots. So I substituted those gain pots with a 10kB dual pot.<br />A dual 10kB was all I had, so I recommend trying a dual 1kB or 5kB pot, because with 10kB the distortion starts changing in the last half of the pots rotation. I'll report the results when I have a dual 1kB to play with.<br />And I made the Bright pot into a typical filter pot, because it was too easy :)<br />Just reverse the connections of Bright-3 and Bright-1&2 on the board AND remove connection of Volume-3 from the board and connect it to Bright-1&2.<br />Here's a link from where you can find the idea (though in my mod there's no resistor after that filter pot):<br />http://www.electrosmash.com/proco-rat-analysis/pedals/distortion/pro-co-rat-distortion.htmlJupnitski77https://www.blogger.com/profile/11582075821084193973noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-48506571323377118352013-08-05T16:13:39.769+01:002013-08-05T16:13:39.769+01:00It seems bright enough for my taste, I might do sw...It seems bright enough for my taste, I might do switchable input/output caps ala the dam meathead for a bit more balls tho'.
