General Questions / Hipster Won't Bias

« on: March 05, 2017, 12:13:59 AM »

this is a really strange one for me. i've built more than 500 different pedals now, and many fuzz faces (both PNP germanium & NPN silicon) that have all sounded great, and for some stupid reason i can't get my hipster's bias down to 4.5V. i socketed the two transistors and have tried a ton of different ones. all of my transistors were checked with my peak atlas DCA55 to be at spec and the 25K trimpot still only adjust from 9V down to 8.98V on all of them.

anybody have any idea as to why this is happening? i even went to the trouble of removing all of the parts and replaced them with measured tested & ones to make sure that i didn't have a faulty component, but i can't figure this out for the life of me.

Build Reports / Southhampton Fifth Gear/ EQD speaker cranker

I just finished this one the other day which is a Southampton fifth gear which as far as I can tell is the same as the earthquaker devices speaker cranker, the only difference on mine is that I used two germanium diodes instead of the silicon 1N60A's in the clipping section.

just finished this one. I added a clean blend and an adjustable (via internal trimpot) booster to the output so it would have unity gain. etched 1590BB with a relayed true bypass and clear knob with a status led.

Build Reports / Madean Rust Bucket (EHX Attack decay)

« on: February 01, 2016, 06:29:52 PM »

I just finished building my Rustbucket. I squeezed it into a standard 1590BB (etched) with side in/out jacks and a top DC jack. I also installed a relayed true bypass. I love this pedal!
