Happy 2022, everyone! Here’s a buffer/booster from Fulltone. Engaged it’s a booster with an interesting controllable germanium soft clipping setup, and when bypassed the diodes and gain control are shorted, creating a buffer. If you’re just after the boost and want to skip the buffered bypass, just ignore the two Bypass pads and wire it … Read more
What’s the OCB you ask? It’s the bypass buffer circuit from the new version of Fulltone’s OCD. It allows you to switch between regular true bypass and buffered bypass. There are 2 versions: The first (smaller) inverts the phase of your audio signal when engaged (in bypass mode phase isn’t inverted). The second (larger) adds … Read more
Stumbled across this schematic on FSB. It’s a buffer/EQ/preamp for peizo pickups, specifically all Barcus-Berry electret microphone systems. I figured most would be building this into an instrument and not a pedal, so all the pots are off-board. If you’re planning on running it only off a 9v battery, you cab get away without the … Read more
Got a request for a dual buffer that inverted the phase of the signal. Found this post from Parasit Studio and used it for the basis of this design. I added polarity protection, power filter cap, and output caps. You can use either dedicated jacks for the in phase and inverted phase outputs, or use … Read more
The Boost ‘n’ Buff is a simple little booster that doubles as a buffer when it’s turned off (so it’s not a true bypass effect). You should be able to squeeze this one in a 1590A. The FSw pads are for the bypass footswitch. If you want to build the second version of the Boost … Read more
If you’re a Dead Head, you’ll probably be interested in this one. It’s the pre-amp from Jerry Garcia’s Tiger guitar used from ’79-’89 and built by Doug Irwin. It’s a unity gain buffer to prevent signal loss with long cables. It can be built into a guitar like the original or into a 1590A. Other … Read more
I know, I know. Another day another layout from me. I mean Jez, can’t I let one of the other guys post a new layout for once this month? You guys must be sick of seeing my name pop up with a new layout… Anyways, this time I decided to do something different the the … Read more
From the Source: The Lehle Sunday Driver SW is a compact-format high-end preamp for all types of electrical and acoustic instruments – a preamp that enables electric guitars and basses, acoustic guitars, and also other stringed instruments (such as violins, cellos and double basses) to realize all of their musical potential. The switchable version expands … Read more
