DIRTY BOOTS TWEAKS

jrod over at FSB is planning on building a DIRTY BOOTS, and asked me what kind of tweaks could be made.  it's really a highly variable circuit, and can be tailored to your specific tone very easily.  here's what i wrote to him-


there is a lot of tweaking that can be done to the DB.  you might want to lower the collector resistor on Q2 as it is a bit voltage starved.  if you want less drive, increase the resistor in between stages, or take out the bypass caps on the emitters.  also, you might want to increase the collector resistor on Q2 as it is kicking out pretty much full gain, and that can make it a bit noisy.  maybe try 1K.  it all depends on what you want.  if you want it brighter, lower the value of the compensation cap from C to B on Q1 or put a 47K resistor in series with the input.  adjust the in and out caps for low end.  it's a really easy circuit to tweak, so i would just put it on the breadboard, and figure out what you like for your amp.

TRIODE FUZZ NO.2/ AMZ SIXTIES STYLE FUZZ TAGBOARD LAYOUT

a while back, i posted this little article on a couple of fuzz circuits i found on the triode electronics site. the first is very similar to a fuzz face style circuit, where as the second is a little bit different. it has what appears to be an emitter follower into a kind of dc coupled complementary gain stage pair. very much similar to the jordan bosstone. here is a link to the original article.

while surfing around the voluminous pages of Jack Orman's AMZ effects website, i saw something that looked a little familiar.

it seems that the triode fuzz and the amz sixties style fuzz are one in the same!  most likely, this is an old circuit taken from one of the many electronics "cookbooks" from back in the day.  regardless, i've heard from a good source that it's supposed to be a great sounding circuit, so i decided to draw up a layout- this time for tagboard construction.  tagboard, eyelet board, or turret board can be a fun way to do your circuit board construction for a change.  there is no etching or drilling to be done, and you get to use those nice sounding axial foil caps that would've never fit on you pcb circuit.  i really like using this particular tagboard that can be found at weber as well as apex jr. for very reasonable prices.

it has 3 different solder points per tag that makes it very easy to find holes for your passives, actives, and wire without running out of space.  the layout i made for the triode/sixties fuzz circuit was made specifically for this type of board, but you could easily adapt it to other types of tagboard out there.  i haven't built it yet, but i do plan to in the near future.  as always, let me know if you decide to build it yourself.

i got this thing on the breadboard, and had a rough time getting it to bias properly.  i'm going to try and figure it out, and i'll post anything i find.

WHO RUNS BARTER TOWN???

some additions to the MASTERBLASTER article have been added, including a new layout and some new mod ideas.  you will be redirected to the article by clicking on this entry's title.

WAMPLER - CRANKED AC

recently while browsing a certain clone kit site, i stumbled across the schematic for brian wampler's cranked ac design. having been on a serious ac kick a while back, i was never able to find the schematic, so this was kind of a cool find. the cranked ac at first looks like your run of the mill jfet type distortion box until you notice that wierd parallel fet configuration. ecaxtly what this is supposed to do to the sound i don't know, but it is a rather interesting little tweak. i'm sure that this could be adapted to just about any transistor type, and wonder if it has any of the same kind of properties as stacking ic's.

i redrew the schematic and made up an eagle verified pcb layout which should work ok. if anyone gets it built please let me know.  you can keep up with all of the latest on this subject HERE.
