Recoomend A Clean Boost

[jacobyjd]

It goes from loud to louder.

That's why it's called a booster! 

Absolutely! I'm not disputing that

However, I found that even at the minimum setting, I was getting TOO much boost when used as a solo booster in my effects loop. It made my bandmates whine

Hi guys,

Can someone recommend a good clean boost.  I built the beginners project but I'd like to build a boost that has no gain and if it has a tone control it'd be great.

Thanks!

You can build my Sparkle Boost, replace the "Gain" pot with a 1k resistor...and then tack Mark Hammers "Stupidly Wonderful Tone Control" onto the end...great sound, easy build.

Hi Mark,
I am just wondering, what boost are you referring to in this post - the beginner project one?

I am personally looking for a boost circuit that just boosts volume (to use on the inputs of a passive ring modulator), preferably using discrete components. A gain of 17.5 would probably do it for my purposes, I think.

It should be a simple enough thing, but searching, I have had a hard time finding this because it seems that most people want a boost that will have some overdrive or will boost treble or some other tonal characteristic.

Thanks

Virtually ANY JFET-based, single bipolar transistor-based, or op-amp based gain circuit would do the trick.  You'll find circuits for them on AMZ, GEOFEX, at Tonepad and GGG, at Don Till's site, and in virtually any op-amp circuits compendium.  Realistically, they almost all have reasonable enough input impedance, and you really only need to start looking at specific design characteristics once the gain starts to exceed 10-15, when the design has to start anticipating how to make the resulting clipping sound acceptable.
