18 watt Stout with Reverb and Hotswitch |

Note that Hoffman boards are not assembled by looking at my builds. I do test builds first and change the designs based on those builds. You assemble Hoffman boards using the documents listed below. The Layout Diagram, Schematic and BOM for this board are on this page |

The 18 Watt stout project was such a great success that I decided to go ahead and design a
Stout with reverb. The amp sounds great and has reverb, how can you beat it? The reverb circuit is based on a Fender
combo reverb circuit but the Stout does not have the deep Fender reverb that a Fender combo has. If you are expecting
surf quality reverb, this circuit does not produce that type of reverb. The amp has an extra stage of gain and all that
is needed is some ambience. This reverb circuit does that just fine. If you look at a Fender reverb schematic you will
see that there are two stages of gain before the signal splits off and is sent to the reverb loop. The stout only has
one stage of gain before being sent to the reverb circuit and so the reverb is toned down and not as dramatic as a Fender
combo. It sounds just fine to me for an amp with higher gain. You cannot use a ton of reverb for higher gain amps, the
reverb needs to be very slight and subtle in this type of amp. You can also build this project with the Hot switch mod on full time and no relay. Personally, I leave the Hot switch on full time. The project would be a bit easier without the relay power supply and relay. See the library page for the Schematics and Layout diagrams. |
