Tools, Tones and Toys for Guitarists
For some reason none of us got my CJ Downbox v2 layout to work. That was a bit of a mystery since the schematic was working correctly on my breadboard, but even though the layout did not have any errors, the flip-flop simply refused to work. I had taken the layout down a long ago … Read more
Request. Moving on from the Fourbanger, here’s a compact layout for the standard Rangemaster but with a voltage inverter so you can use the better quality PNP transistors but with a negative ground. Note the IC is rotated 180° to how we usually mount it, pin 1 bottom right. To make this a little more … Read more
Another great sounding quicky from Jimi, no pots or toggles and so a nice 1590A build, although I’m sure Javi will manage to get it in a thimble :o)
This could well be the ultimate tweakers boost pedal, with a switchable Rangemaster (PNP transistors but negative ground), Super Hard On, Opamp and JFET booster. The one change from his original is that I have included the original SHO circuit instead of his Crackle Not OK version of it. Each booster has its own gain … Read more
Fender’s take on trying to get EC’s strat to sound like a Gibson. Some people seem to like it a lot, while others.. Not so much. But as i stumbled on a schematic, i thought this could work well as a pedal. With four transistors and not-so-simple design, there’s little chance of fitting this onboard … Read more
Jack uses some fancy clickless switching for this, and as it is PIC controlled it allows him a lot more options so he was able to program a quick double click to enable the Ultra Boost mode. This has been simplified slightly here to use simple true bypass switching, and without the PIC functionality the … Read more
Strange. I thought we had this already covered, but apparently not. The layout didn’t turn out as compact as i hoped, but there’s still some symmetry in there and at 21×15 it will with in 1590B with ease. So this is the original transformerless Octavia that comes in Rocket enclosure. Apparently the last version Mr. … Read more

Updated 24th March 2018 – misplaced link corrected. Thanks to music6000 for the heads up. Thanks to YuGi from freestompboxes.org and the fennecelectronics.it forum for the schematic. This is an interesting design and with loads of non standard values just to annoy us! Info about the original: THE SECRET-1 STANDARDWhen the Secret-1 Ltd first came … Read more
