Cruz Drive by Jon Patton

6/28/2015

5 Comments

 
This is Jon Patton's adaption of the Tube Driver, but it uses a JFET insted of a tube. It also has a few extra goodies thrown in such as an 18v chargepump and a mids switch. This circuit sounds very good IMO and has excellent controls and a wide range of tones. Thanks to Jon for sharing his work!

DiSCO - Dirty Compressor and Overdrive

4/7/2015

1 Comment

 
Edit 2015-06-12. Updated the layout slightly to match the latest schematic. Anode of D7 moved down two rows.

Here is another very nice compressor / overdrive. This one is a brand new creation from Sam Hay, the inventor of the Cherub Chorus that I posted a layout for earlier. Read more about it in the original thread here.

For schotty diode I used a 1N5817 in my build with good results.

Elektor Compression and Distortion

4/7/2015

Here is an old circuit from Elektor, a dirty compressor and distortion in one. I was surprised that this one actually sounds really nice. The compression goes from fairly clean and subtle to very compressed and dirty. The distortion isn't bad either. :)

I didn't have a BF256C, so I tried both a 2N5457 and a BF245B insted with good results. Just keep in mind the pinout.

ETI Guitar Note Expander

Another CD4007 based circuit. I was hoping this one could deliver some cool sounds. However, I found that many settings of the rotary switch doesn't sound very useful and the overdrive is lacking.

Discrete Tube Reamer

This is discrete version of The Tube Reamer by Runoffgroove, a very stripped down Tube Screamer. Posting the Flying Guillotine Fuzz reminded me of the "Diode Compression Op Amp" by Joe Davisson, as used here insted of a 4558 IC. It's been reported to sound smoother. Maybe I'll have to built the IC version to compare. :)

I found it a bit too bright and recommend Increasing the 33nF cap to 47nF for less highs.

I just realized I forgot to post my HM-2 layout that I did a year ago.

AMZ Mini muff distortion

6/12/2014

The "Mini-Muff" by Jack Orman is basically a Big Muff with two of the gainstages removed. It doesn't sound much like a Muff, but makes a surprisingly good overdrive/distortion.

Here's an interesting Fuzz by RA Penfold from the book Music Projects (1994)
Moosapotamus has a good article on why it's a bit different from the usual fuzz.

Mesa Grid Slammer

Here's a vero layout based on my own tracing of the original Mesa Grid Slammer pedal. Read more about the tracing process here. Unfortunatly it's nothing more then a TS-9 clone with a different diode clipping configuration, but a good sounding overdrive non the less.
