Request, layout for the Leegazzy Carvin Legacy emulator by Antonio Pelaez. I’ve shown a big axial cap as a filter in this one because there was plenty of space at the top and I have them exactly the size shown, but as always it will work just as well with a radial electrolytic, and you … Read more
Another one of the amp emulation circuits I’m collecting at the moment, this one based on the Bogner Uberschall by JOK3RX on freestompboxes. You could get this in a 1590B but with two stomps, a toggle and 5 pots it may even be a pain to put in a 125B, so as with the other … Read more
While in the mood for amp sims I thought I’d add this one which I think sounds excellent in the demos. Similar sort of vein as the Diefet, but this time based on the Bogner Ecstasy. It’s a 9V circuit, but I thought it would again be worth including a charge pump with this and … Read more
With 7 pots this was never going to be put in a 1590B anyway and so I wasn’t so concerned about keeping the size down, although I bet it could fit in a 125B and would be very impressed if someone did it. :o) I think most people will opt for a 1590BB though. This … Read more
Another request for a discontinued Madbean board, this one based on the Dr. Z Carmen Ghia preamp. Info about the original project and board: The Rump Roast finds its origins in the preamp section of the Dr. Z Carmen Ghia amplifier. The Carmen Ghia is a very understated and elegant design consisting of a single … Read more
One of the layouts that is frequently mentioned so I thought I’d do a tagboardeffects version of it. There’s a couple of axial electrolytics in there, simply because I have them in that size and to me they suit the layout as it is better than radial, but as usual, use whatever you have. Info … Read more
Info about the great ROG Ampeg emulation project: The Flipster, runoffgroove.com’s only circuit primarily intended for use with a bass guitar, was released in June 2004. It was another adaptation of a vintage tube amp for use as a distortion pedal, namely the Ampeg SB-12 Portaflex introduced in 1965. Several bass players in the DIY-fx … Read more
JHS’s ROG Supreaux Deux! From the inception of the Supro Company in 1935 until its closing in 1968, no other brand of amplifier has had such a fascinating, mysterious and legendary story. The Supro® amps deliver the voice of rock and roll, from Jimmy Page’s legendary Led Zeppelin recordings or Brian Setzer’s early Stray Cat … Read more
*Errors at the tone stack section have now been fixed…*Errors in the schematic (coupling caps at 0.068µ and not 0.68µ) have now been fixed on the layout… As requested. Paul Nelson‘s Orange Graphic MKII stomp box adaptation. I knew this one will get huge the minute i saw the schematic, but it turned out a … Read more
A request. Info from ROG: One of the often overlooked Fender amps is the tweed-era Princeton. They are excellent guitar amps, especially for blues playing. The major drawback was the 4.5 watt output wasn’t enough to keep up with a band. Again, using the technique pioneered by Doug Hammond, we decided to try to capture … Read more
