Tengo un Bugera V22 que tiene un botón de Booster que por lo visto para solos va fenomenal.
Estaría de PM poder controlar ese boton con un pequeño pedal.
Parece que los yankis ya lo han hecho pero, no acabo de entender como hacerlo.
A ver si alguien lo entiende más o menos.
A month or so ago I promised to work out a boost switch/ footswitch mod for the V22 ... i 've forgotten who it was that was interested, but true to my word, I ripped my amp apart and worked it out.
I thought about installing the mod to mine, but I don't really need it so I gave it a miss...
The mod is pretty simple really, the boost works by bypassing a 10 Mohm resistor in the tone circuit. All you need to mod the amp is a bit of hookup wire, a 1/4" stereo socket, a good shielded stereo input cable and a stomp switch.
You will need to solder two leads to the back of the boost switch or one to each leg of the 10 Mohm resistor as shown in this photo:
You will need to mount the 1/4" jack to the back of the chasis and solder the leads to the tip and the middle ring, NOT THE SLEEVE! the sleeve is your ground and needs to be grounded to the chasis.
Try and keep your cable as short as possible, you don't want to add any more resistance than you need to...the object of this mod is to mimic a dead short so using 30+ foot cables could have a negative effect on the tone. Just keep them short and it should work out fine.
Just a word of warning:
1. This mod WILL negate your warranty
2. Unplugging the amp & connecting a 47 k ohm resistor from pin 3 on V1 to ground (the chasis) for a few minutes will get rid of the zapper and possibly eliminate all of those expletives you would have used when you got bit.
3. A soldering iron is not a toaster. If you overheat components they will die.
4. This mod "SHOULD" work just fine, however if it doesn't and your amp blows up and kills grandma... you are allowed to shout four letter words and call me names, but you can't throttle or sue me.
