Default Guitar Pedal

Hi Y'all

I would like to build a very simple active Stomp box for guitar
that would provide about a boost in gain.
Similar to a pedal that Roland offers without the EQ portion.
The idea is to replace a volume pedal not make distortion.
This box would boost the signal a bit for lead or cut it back for rythm.
Does anyone have a circuit for this? Or could possibly recommend
a chip to use? Op Amp?
Something that uses a 9V battery.

Thanks

You don't need an op-amp or anything that needs 9V!
You can do it only with a pot.If you want LEDs add a battery.
See here and

That Solo Pro would do it. It's basically like adding two volume pots to your guitar with a switch to switch between them.

I'd think you'd want to use a 100k or 500k audio taper pot like your guitar does. Though 1M shouldn't do anything, just gives more resistance the more you turn it.

Yes, that's an A/B level circuit, but that's passive, and would not add gain to your signal. Try www.generalguitargadgets.com and look at those mini-boosters or something like that...

You can buy a little Danelectro EQ pedal for about $30. Adjust all the EQ controls the same amount up for an across the board boost. It does what you want. CLicking the pedal in and out puts the boost you want in and out.
