This is a modded Benson Preamp by Dylan159 on Freestompboxes. Dylan has taken the original and simplified it but has retained the overall character. Quite a detailed explanation via the link above, including a schematic, LTSPICE model traces, audio and his vero layout. What a solid effort. For me, this is useful, as it has a standard … Read more
Full details available here, which is my point-to-point layout for the Matsumin Valvecaster. Original values are used below. MATSUMIN VALVECASTER – TAG BOARD LAYOUT
One of my older vero layouts for the Benson Preamp that I posted on Guitar FX layouts forum a while back – updated due to the bass and treble outer lugs being the wrong way around… I have previously posted the point-to-point version, but I forgot to post the vero layout at the time. I … Read more
This is one of the first circuits I ever built due to the simplicity, and it’s hard to go past as a simple boost with a bit of fattening up of the signal. The Echoplex EP-3 preamp doesn’t provide tons of gain, but it does work very nicely as a slight boost, or as an … Read more
The Hudson Electronics Broadcast is a great little pedal – while now overshadowed by the Dual Broadcast, which has the high and low gain settings on a foot switch with individual level controls, it’s essentially the same under the hood. I never thought a lo-cut pot would be so useful until trying this pedal. It … Read more
I quite liked the single Hudson Electronics Broadcast; the Dual is just that little bit more practical. It can run from clean through to downright nasty tones. The low-cut is really great too. You will need to build a 24v charge pump for this or run the entire thing at 9V – which does work, albeit … Read more
Got a little simple boost/preamp for your Thursday. Should be a pretty easy fit in a 1590A. J113 alternatives would be J201, 2N5457, and probably a couple other JFETs that are obsolete. 😑
Apparently it’s tube week. Here’s the Tube Driver made famous by David Gilmour. It uses a 12AX7 which is pushed by a dual opamp followed by a Fender-style tone stack. I kept the power section from John K’s version of the Blue Tube. Fits easily in a 1590BB. Here’s the schematic for reference.
Came across John K’s vero of this circuit with a few mods (Mid pot, bipolar charge pump) and figured we needed a layout for it as well. Runs on 9-12v. Pots are all board mounted with the tube off board. Here’s John’s original layout.
Originally a bit of a flop from Boss, the FET Amplifier was made famous by U2’s The Edge. It features a 2-band Baxendall tone stack and the Volume control is more like a gain control. Originals use 2 single opamps that are pretty hard to come by these days, so they’ve been replaced by a … Read more
