Tools, Tones and Toys for Guitarists
From ROG: This project has returned from beyond the grave for a tune-up. Compressed, harsh, and ’80s sounding are fitting descriptions of its sonic character. Yes, it is a niche sound which is quite the opposite of some JFET-based distortions developed by the ‘groove, however we feel it is a great time capsule of an … Read more
Jon Patton’s Bearhug FET Compressor (Yeah! That’s the same cool dude who demoed Valvewizard’s Engineer’s Thumb a while back!) As requested. From Jon: The Bearhug is a (fairly) low-parts-count, quiet, tonally transparent compressor using only transistors. It can do subtle peak limiting or squishy sustaining, with a decent amount of boost (probably ~6-12db). Notes & … Read more
Apparently there was some slight issues with the schematic above, namely the R6 was not correctly placed – that had been corrected in the next ETI issue back in 1993. The layout seems correct to me.. 🙂
As. Requested. Info from ROG: There has always been much talk about the mystical hand-built amps that a particular man sells for around $10,000 each. Some claim these are the greatest amplifiers known to man, while others maintain it’s all hype. The runoffgroove.com team doesn’t know for sure, because neither of us can plunk down 10 … Read more
Zero information around about this circuit. The schematic is signed by Alquinta, and the design looks really nice. Only info i could easily find was the little note on the bottom schematic file: “Bass overdrive with a dirty edge (Low to Med Gain)” The transistors (Q1-Q3) can be 2N5089, BC549C or similar. John’s modded layout: … Read more
Request. A compact LPB1 layout with a trimmer instead of the external pot which can be used as an internal booster for other effects that need a bit of a push and if you do want an external volume control
This design is pretty close to OD250/Dist+, but i thought it should be added anyway, as there are some slight differences. Funny thing is that the same circuit was marketed and sold as both Vox Distortion and Guyatone Zoom Distortion Box. From what i can tell from the demo, it’s really nice sounding thing. These … Read more
Geiri verified this one and made a cool demo! On his build, the gain pot is wired in reverse – that has been fixed in the layout below. Mark Hammer’s Chaos Distortion is turning 10. From Mark Hammer: A friend’s son wanted a heavy-metal kind of thing so I thought I’d try and do something … Read more
Request. Manufacturers info about the reissue version which is a circuit match: The WH10V2 features the same circuit as the original with one major upgrade: a very sturdy metal housing. Ready now for the rigors of the road, the WH10V2 features the same multiple feedback opamp circuit as the original, a type rarely found in … Read more
