thanks kaycee.kaycee wrote:You could keep the original tone section, and add a tone knob. Taking the output from after the diodes and run it to a pole of a DPDT switch. On one side have the route through the normal tone stack with the two position switch intact. On the other throw you can insert the tone stack of your choice, the other pole of the switch goes to the volume pot.
You can try whatever tone stack you like, I'd suggest the Stupidly Wonderful Tone Control that Jack Orman put out, works quite well on this circuit. Does it cover the ground of the original tone selections? Kind of.
had tentatively come to the same sort of conclusion (re keeping tone 1 and 2 as stock, and patching in an adjustable third tone option to the third position of the on-on-on) but it's good to have the reassurance of someone who has done it and it worked for. just a matter of which stack is most sympathetic to the qualities of the original. too toppy and it ends up in tinny fy2 wasp-in-a-coke-can territory, and two much bottom end and it muffles out.
have investigated the orman swtc after you mentioned it to me re poss mods to an ibanez standrard fuzz i built (which i abandoned after building it with the vero strips running vertically instead of horizontally, my best fail to date). i also read up on some extensions and varations to it by rg keen i think, or mark someone (it was either amz or geofx, i think, have got them all in a word doc somewhere). so have options to work through.
finally got some more breadboards yesterday. keep filling them up. six now with different builds on. when they are must-have they get promoted to being soldered up and boxed). so one will now become superfuzz tone stacks.
drag is i'm too ill to get out to anywhere i can use my valve amp. so reduced to a little tabletop amp with no bottom end. or headphones, which tends to overstate the bass. which is why i was wondering which 'should' keep (in 'theory') as much of the original range as possible, in pure circuit physics terms. the derringer scoop trim looks least intrusive. not sure about the wattson. i just don't know enough yet to judge.
anyway, rambling on. will def put swtc on breadboard and report back as and when.
