Members grishnakh Posted November 20, 2006 Members Share Posted November 20, 2006 I'm planning to put together a dallas rangemaster and would like to know what needs to be done to toggle from treble to full boost. Thanks Link to comment Share on other sites More sharing options...
Members Lanefair Posted November 20, 2006 Members Share Posted November 20, 2006 You need to change the value of the input capactitor. I can't remember if it needs more or less though sorry. Link to comment Share on other sites More sharing options...
Members ZachOmega Posted November 20, 2006 Members Share Posted November 20, 2006 Lanefair is correct. The input capacitor is something in the ballpark of .0047 to .0056uf. You want something more like .01 to .1 uf for a full boost. -Zach Omega Link to comment Share on other sites More sharing options...
Members GRINGO_LOCO Posted November 20, 2006 Members Share Posted November 20, 2006 Personal opinion here, so take it however you like. I don't "like" Rangemasters when you get "too much bass" into the circuit. They just aren't designed to be "full range" boosters. In my experience, a .1uF cap just lets too much bass in for "this" circuit. There *is*, however a great "happy medium" between full range and treble booster that sounds excellent. Try a .022uF-.047uF cap for the input cap. Plenty of bass, without getting too "flabby". my $.02, GRINGO Link to comment Share on other sites More sharing options...

I have built several of the circuits and I have found that a .0068, .01 and a .022 sound pretty good. You can put a few values on a rotary switch to compensate for different guitars/ pickups.If your amp is pretty bright, you can use a 25K potentiometer instead of a 10K it will not drive the amp as hard, but it will thicken up the sound a bit. Most of all use quality components in the circuit such as orange drop caps and at the very least metal film resistors and wire them point to point, this cuts down on noise.
