If you're modding your pedal by desoldering the existing parts and soldering in new ones, you may have trouble if you want to swap parts in and out multiple times given the fragility of circuit board traces.<br /><br />If it were me ,I'd breadboard the circuit first, make sure the mods were what I wanted then modify the pedal. Of course, if this is just an experiment and you're not worried about the pedal, then go for it.<br /><br /><br /> <a href="http://www.freestompboxes.org/viewtopic.php?f=11&t=29994">Read the main topic related to this post</a><hr /> Today, 18:04 http://www.freestompboxes.org/viewtopic.php?f=11&t=29994#p276076 capacitor u1J163 http://www.freestompboxes.org/viewtopic.php?f=17&t=29996#p276075 <br /> by plush (Posted Today, 17:07)<br/><br /> <blockquote><div><cite>rpc66 wrote:</cite>what about the J1?</div></blockquote><br /><br />Here mistakes were made.<br /><br /><br /> <a href="http://www.freestompboxes.org/viewtopic.php?f=17&t=29996">Read the main topic related to this post</a><hr /> Today, 17:07 http://www.freestompboxes.org/viewtopic.php?f=17&t=29996#p276075 B15-N Portaflex style preamp http://www.freestompboxes.org/viewtopic.php?f=2&t=21081#p276071 <br /> by Dr Tony Balls (Posted Today, 14:33)<br/><br /> Sure:<br /><br /><a href="https://flic.kr/p/WS2EQS" class="postlink"><img src="https://live.staticflickr.com/4418/36009416050_74c374404e_z.jpg" alt="Image" /></a><br /><br /><a href="https://flic.kr/p/WS2CBy" class="postlink"><img src="https://live.staticflickr.com/4411/36009408550_feae068cd0_z.jpg" alt="Image" /></a><br /><br /><a href="https://flic.kr/p/WS2CB3" class="postlink"><img src="https://live.staticflickr.com/4363/36009408520_54bb8b11a8_z.jpg" alt="Image" /></a><br /><br /><a href="https://flic.kr/p/WS2EzG" class="postlink"><img src="https://live.staticflickr.com/4439/36009415170_701892b89f_z.jpg" alt="Image" /></a><br /><br /><br />Also, much more recently I made these EF86 boosts.

It was sold to me as an old Fender FDS-90 distortion pedal, and I don't have any reason to doubt that, but I can't really find much information on the web about it. <br /><br />I've read that it was made by Maxon, which seems likely, since the enclosure looks like their Japanese -01 Series, and has the Maxon M cast on the inside. I've also read that it's a rebranded Maxon SD-01 Sonic Distortion, which I thought I remembered reading somewhere is a Maxon branded version of the Ibanez SD9 Sonic Distortion. I don't have an actual SD9 to compare it with, but it sounds fairly different from the SD9 side of my Keeley DS-9. Actually, it sounds pretty close to a Boss DS-1.<br /><br />I've emailed Fender about it, and they really don't have anything on it.<br /><br />So, does anyone here have any info? Is it really a rebranded SD-01? Does anyone have a schematic for it and/or the SD-01? I may eventually trace it, but for now I'm too lazy...<br /><br />Thanks!<br /><br /><br /> <a href="http://www.freestompboxes.org/viewtopic.php?f=1&t=29989">Read the main topic related to this post</a><hr /> 22 Jun 2019, 14:37 http://www.freestompboxes.org/viewtopic.php?f=1&t=29989#p276018 Fulltone - OCD http://www.freestompboxes.org/viewtopic.php?f=7&t=527#p276009 <br /> by Cigla tel.
