paul_5 Posted June 6, 2013 Share Posted June 6, 2013 (edited) So anyways, a load of MPSA14 darlington transistors arrived today. Scramblers ahoy! Edited June 14, 2013 by paul_5 Quote Link to comment Share on other sites More sharing options...
GarethFlatlands Posted June 6, 2013 Share Posted June 6, 2013 Interesting pedal. I built a BYOC clone but I'm not sure what went wrong as it needs a really hot signal, otherwise it chokes out very easily. My old active Warwick was fine but my single coil guitars sound awful with it Quote Link to comment Share on other sites More sharing options...
paul_5 Posted June 6, 2013 Author Share Posted June 6, 2013 got some HOT 'buckers for the SG and both of my basses are active; it's all good! Quote Link to comment Share on other sites More sharing options...
GarethFlatlands Posted June 6, 2013 Share Posted June 6, 2013 Are they supposed to do that then? I thought I'd messed the build up somewhere! Quote Link to comment Share on other sites More sharing options...
paul_5 Posted June 6, 2013 Author Share Posted June 6, 2013 Dunno, w It's got a horrible, nasty, spluttery/gatey/spitty sort of sound to it - you can see why they put a blend on it! Mine's mounted in the same box as my Colorsound Bass Fuzz clone so I can switch between dirty sounds really easily. Quote Link to comment Share on other sites More sharing options...
NoirBass Posted June 7, 2013 Share Posted June 7, 2013 (edited) I've been wanting to build a clone of this too, even got hold of 2N5306 / BC169B's to do so. Did you build it on vero or PCB? any mods for bass? The Coloursound BF is a beast, one of my favourites.

paul_5 Posted June 7, 2013 Author Share Posted June 7, 2013 (edited) Built it on veroboard. It's [i]really, really[/i] vicious when you push it - probably unusable on bass without the blend control, although if you turn the 'texture' knob down it gets really mellow. As for mods then the obvious place to start would be to alter the input cap to let more bass through to the drive stages... I'd start by whacking that up to .1µf and seeing what that sounds like.

paul_5 Posted June 10, 2013 Author Share Posted June 10, 2013 (edited) replaced the input cap (10nf) to 0.1µf and it's made chuff all difference. I think I'll have a closer look at the schem tonight. Sounds AWESOME on guitar though... Looked at it in a bit more detail but can't see where the low end is being lost. Maybe there's just too much octave/filth in there...

paul_5 Posted June 14, 2013 Author Share Posted June 14, 2013 (edited) Samples - [url="https://soundcloud.com/paul_5/sets/amp-eg-scrambler-clone-samples"]https://soundcloud.c...r-clone-samples[/url] It's not [i]quite[/i] as dirty as it should be as I used a 2n3904 instead of the 2n5088 transistor as Q2, but it's still pretty extreme!

NoirBass Posted June 14, 2013 Share Posted June 14, 2013 I like it! Good job sir. Need to get a few other builds out if the way and this will get built soon. Sounds like its got plenty of bottom as it is so I think I'll build it stock also. Quote Link to comment Share on other sites More sharing options...
