Tools, Tones and Toys for Guitarists
I’ll be posting a few circuits from Dylan159’s Unreleased Ciruits. There was the Fuzz Facelift posted earlier and i’ll continue with more of these goodies. Next up: Troupple boost. Gamers might get the reference. This came out from my wish for a simple, clean treble boost that could work from a variety of supply voltages … Read more
Someone mentioned that the circuit in an earlier post would have possibly been an inspiration for this one. Not sure if i share the sentiment, since that 80’s japanese design and this have basically, or in quite broad terms, just the gain pot method in common with each other. Anyway. Quite a few people seem … Read more
Second post for today is the Overdrive from Manfred’s trace (at FSB). This comes from the same series as it’s distortion brother (see the earlier Vesta Fire Distortion post), but the design is slightly more obscure. Still, the inverting input filter path to ground gain pot method on a non-inverting gain stage is used. However, … Read more
Not that long ago, Manfred traced his Reagun Distortion unit and posted the results on FSB. These pedals were sold as Vesta Fire, Nadine’s and Reagun brands around early to mid-eighties. All these were made by Shiino Vesta Fire Corporation (SVFC), which became Vestax back in 1987. Designwise these are not bad at all. This … Read more
Next up from Vitalii’s traces is Moon Metal from later Exar series. Youtube demo found isn’t all that great, but there’s very nice EQ section and gain range seems quite good as well. Not a small circuit, but i think this could be quite usable.
Traced on FSB by Asbestosaurus, this circuit looks at a first glance a bit like OD250/Dist+, but no. And the Sense control makes this quite interesting. I built my layout version one, but this is redrawn to make it better.. Anyway, nice to see something cool done to a single opamp drive topology.
This one is kind of a take on a single opamp overdrive with hard clippers ala OD250/Dist+, but the gain control is placed on the feedback loop like in many standard overdrive designs. Nothing too speacial or different, but a nice addition to overdrive palette nevertheless. Snippet from the spiel:The BL-8 delivers a creamy yet … Read more
Another one from Vitalii’s traces. This one seems quite nice modern metal distortion with reasonable frequency characteristics. Should be enough gain too. The 47K at the top (horizontal one) may be a point to tweak for even more over the top gain. Like so many of these pedals of Polish origin, this one seems to … Read more
Traced by GratefulEight, this overdrive seems like a circuit worth to try out. From the source: The Earth Drive is the ultimate boost/overdrive pedal, designed to retain your instrument’s natural character while providing an organic, full-bodied, yet transparent sound. Use the Earth Drive as a clean boost to add warmth and smoothing, or turn up … Read more
