Hi All,
Looking for any links or ideas for boosts for a tube amp input jack.
Granger amps has a couple of options superFET jack and another using PN4392.
I like the idea of the superFET jack as the gain can be adjusted with a trimpot that is accessible through the input jack.
It m sure I've seen this elsewhere years ago.
The aim is to modify a fender style high low jack arrangement to high and boosted.
Is my own diy tube amp and I am experience with the safety with the b+ voltage
What do you suggest?
Hey! That's pretty cute!!

Any amp can be pot-adjusted, on the input or the output.
Wasn't an extra preamp stage a key to the first Mesa Boogie amplifier?
