Prepare for a bit of rambling: I was looking through the de-goup thread for the Cornish G2 over on Freestompboxes.org and was intrigued by the buffered bypass switching that’s used on that pedal. (Before people bombard me with requests for the G2, don’t worry it’s coming.) Original G2s have individual PCBs for the footswitch, the … Read more
Got a request for the Pete Cornish Buffer in dual form like the one I did with the Klon Buffer. So here’s both a single and a dual Cornish Buffer. The original uses a 1N5401 for polarity protection, but a 4001 or similar will work too. And you can probably get away with a small … Read more
In an effort to make my own personal pedal board better, I’m building buffers at the input and output of my signal chain. As space and DC jacks are always a premium, I thought to build a dual buffer in a 1590A enclosure. The Klon Buffer is great and since it only uses half of … Read more
Here’s a simple buffer from JHS. It really only uses one side of the opamp (why not just use a TL071?) and the extra resistors on the other side are just to meet the manufacture’s specs for an unused side. I couldn’t find a schematic for this one, but drew one up from lvlark’s vero … Read more
Here’s a well designed buffer by Martin from SoulSonic FX. Use it as a stand alone buffer or as an output buffer in another pedal. Should fit easily in a 1590a enclosure.
Here’s a simple one for your Saturday. As the name implies, this is a simple buffer based around a JFET transistor. This layout follows the schematic from Jack Orman’s great article on Basic Buffers. Thought this would be useful if you want to add an input buffer to an existing pedal or to a project … Read more
Who doesn’t love a Klon, right? Here’s the buffer stage of the Centaur. The original Klon uses one side of a TL072 for the buffer and the other for gain stage. If you’re building the just the buffer, you can get away with a TL071. I’ve laid out a perf and PCB for each.
Following a couple of threads in the forum where people had oscillation problems with certain effects that disappeared when a buffered pedal was placed before them, I said I’d do a post on here with a few different compact buffers that people could try tucked away in the box to place in series before the … Read more
And seeing as I’m doing little ones tonight, this is the buffer section of the now discontinued (both product and company) Axess BS-2 Buffer/Splitter, and for once isn’t just a rehash of a generic unity gain buffer (although to be fair none of these are going to be too far removed). A charge pump gives … Read more
Traced from gutshots on the blog forum posted by hahafender, thanks for the pics buddy :o). Some of the traces on the unused side of the opamp weren’t visible but the left hand side is a generic opamp buffer and that’s the important bit. I think the resistors used on the other side we’re just … Read more
