DOD FX55B SupraDistortion – BigBuff Mod abram, September 16, 2014August 9, 2019 Here’s another in a line now of DOD pedal mods. For this FX55B, I decided to go for more of a BigMuff sound. Playing around with this pedal initially, I found it to be like most mass-produced distortion/fuzz effects. It had a very thin sound and that notorious volume drop… Continue Reading
the Triode: final build abram, May 2, 2013 final build of my take on the Mitsumin Valvecaster. Continue Reading
sqrt() reverb… abram, February 17, 2013February 17, 2013 this was the final build before it shipped out. circuit is a simple MOSFET (BS170) driver stage followed by two JFET (J201) recovery stages. i’ve included a sound sample of a similar reverb i built later without the second recovery stage and clipping diodes. it makes for a much more… Continue Reading
work in progress abram, December 3, 2012 early stages of a reverb effect pedal for guitar. Continue Reading
MOSFET overdrive… final build? abram, June 11, 2012November 15, 2012 i might add some labels for the pots and contact info, but it’s done for the most part. Continue Reading
PT2399 build… abram, May 19, 2012May 20, 2012 this is an older build now, but i wanted to post it while i’ve been on the subject to record the process. believe it or not, i still have some work to do on this one. i used a TL082 as a buffer for the mixing circuit. getting the gain… Continue Reading
MOSFET overdrive… abram, May 18, 2012June 9, 2012 a forced contract job for Ryan of Falcon Scott. he’s been having some issues finding an overdrive suitable to his hollow-body guitar. i just got a lot of BS170s and thought this might do the trick. the distortion is pretty squared off on the oscilloscope and crunchy. the left pot… Continue Reading
the Stirgiform PT2399 delay… abram, January 21, 2012March 6, 2012 two days worth of soldering and layout. it’s a combination of the Magnus Modulus and Rebote delay schematics. i couldn’t get the mixing circuit to really work from the Rebote schematic (an older version) without some serious distortion, so i just kind of reworked it on my own. here’s the… Continue Reading
