Tools, Tones and Toys for Guitarists
A vintage pedal from the 80s. I’ve removed the flip flop switching system and buffers (thanks Zach for the help). Hopefully it will fit in a 125B box. You can find original thread and schematic here. Updated schematic is available in our Forum section. Thanks Dino for his explanatory video. 12/11 Layout Updated! Readded the … Read more
A little blog update: You may have noticed there wasn’t a post yesterday and that there is one today. Why on a Tuesday and not a Monday? Some big-ish changes are coming to the site in the near future, which (along with a bunch of other small things) is taking up a lot of my … Read more
Gotten several requests for this one and for good reason. It’s probably the best optical compressor design out there. This one’s not for the feint of heart, and will take up most of a 1590BB enclosure. 3 jumpers, but the pots are board mounted. The on/off indicator LED in the original is a bi-color LED … Read more
Here’s Way Huge’s take on the Ross Compressor. This is based on an original from the mid 90s that was traced over on FSB. It will fit in a 1590B with side mounted jacks or a 125B with top mounted jacks.
A modified Ross Compressor. Two simple controls sustain and level. Unfortunately, I haven’t been able to find a video for the MKI, but as we all know if it’s been modified by Mr. Huge it’s going to sound great. Note: There’s a cut under D3 to the left of the 1nF cap that’s hard to … Read more
Not much info on this one, but basically it was a compressor made by Univox in the 70’s as part of their “foot” series. Seems to be loved by many and was recently requested. In addition to the schematic posted in the request section I found another schematic posted over at FSB, so I made … Read more
There have been a few different iterations of the Soul Preacher. This one follows the version that isn’t based around an OTA chip (much like a DynaComp), but is rather much closer to an Orange Squeezer. The original used a buffered bypass, and I’ve included an extra pad for the buffer out if you want … Read more
Got a request for this one. It’s very similar to Bjorn’s Pale Green Compressor in his BearFoot Fx line, but with an extra stage for the Sustain mode. Here’s the schematic for reference. From the product description: FOREST GREEN COMPRESSOR (FGC) is designed to meet the highest standards of guitar and bass compression. There is … Read more
Here’s a really nice optical compressor from Demeter. It offers vintage studio compression that’s very transparent and a fairly simple simple build as well. The trimpot sets the gain of the compressor’s preamp stage. If the signal is distorted, turn down the trimmer till it’s clean. Here’s the schematic for reference.
Here is a layout for the older version of EH Black Finger. You can find the original FSB thread here. I’ve used Pedalgrinder slightly modified schematic on page 3. Some suggested high gain, some low gain transistors. Should test them both. … and the LM13700’s version:
