Title: Rangemaster Boost (SoundClip Added)
Post by: PhiloB on April 16, 2015, 06:06:58 PM
I measured a bunch of Russian germanium transistors for a fuzz face and decided to make good use of the extras.  Here is a Dallas Rangemaster with 'pregain' 250k pot and input caps on a toggle.  Forgot to write down the input cap values but used a on/off/on toggle mounted on vero strip.  Middle position is the stock value and the outside positions add a cap to make 'mid boost' and 'full range' boost.  I built the circuit a couple months ago and didn't take notes:(
I like it quite a bit for what it is. 
The enclosure is etched and painted using model car acrylic paints.
I tried to cover the fresnel LED lens with envirotex but it didn't quite cover it.  I wouldn't do this again mainly because the ET scatters the light when lit.  Not as clean a look when lit IMHO.

Snazzy looking!  Toggle was a great feature improvement as well.  Dual color FTW.

Phil, I think the led/fresnel looks great!  I can't tell any flaws.

Thanks guys.  Certainly drew a lot of inspiration from around here.  So many spectacular etches.  This one was simple in comparison;)
I found where I had planned out the input cap toggle vero.
4n7 as the original.  Then 22n in  parallel or 33n in parallel.  Not sure if that was my final values because I socketed and tried some different values.  Seems I went higher on the last cap.

That is slick looking, and the led looks plenty bright to me.

LED is bright but it actually 'lights up' the epoxy around the LED.  Not a big deal by any means.  I won't do this again because I feel it doesn't add anything and has that minor issue of stray light in the epoxy.  I don't think anyone would actually look at it and say they don't like what's happening.  Guess what I'm saying is that I'm overly critical;)

Thanks Cooder.  I forgot to mention the guitar you hear at the intro is the dry signal.  The other 2 guitars are both pots fully clockwise- one neck position on a strat and one bridge.

That sounds great!  Was the toggle in the "stock" position for the demo as well?
