Yo bassman out there! Booster question?

[The French connection]

Did anyone have an idea of what booster could be suitable for bass guitar. I'm looking for a one knob killer. I've tried a Hog's foot (Mole) but it cuts too much mids/highs and it become really muddy. I was thinking about LPB or AMZ mosfet boost but i'm not sure if i had to change the input cap for the bass frequencies. Did the NPN boost could be a good candidate also? What i need is a booster that will give a little 'hump' to the sound and gonna overdive at high level. Some kind of presence booster with grit at high level. It's gonna work in conjunction with a colorsound bass fuzz all together in the same box.

Thanks!

reply 16 I have built that note the curves and limited gain change.  For a passive bass
You can change the EQ for more high end by increasing C5 this also reduces the lower frequency range gain.

The NPN boost ver 2 sound interesting on bass at low gain settings again with a passive bass.  I have built this people seem to like it.

You can also use a TS a dist+ all kinds of boosts and overdrives etc.  If you play live you don't always need more of all the frequencies you often only need a an EQ to fit in the mix with more in some areas and less in others
Most basses have a high enough signal level and bass amps often have enough gain
So I will guess you need an EQ more than a boost
Adding more bass is sometimes what you don't want to do.

How about Dan Armstrong's Yellow Humper?

Thank you! L1 is an inductor? These component scares me a bit and seems pricey. What is the use of these component in this kind of circuit? Is it in regard of impedance and filtering? Does it really worth the complexification for the final result? I use the npn boost (beginner project) with my guitar and it's one of my fav booster but does this version 2 is a big improvement. I'm a hobbyist and i'm looking for something simple and effective for three bassman friends (all passive bass). They love the fuzz but find the boost (The Mole) useless. I think they are looking for something that gonna give a little help in the mix when it's getting hot. I got the feeling a LPB will do the job but i want something 'sexier' for them, that's why i was thinking about the NPN boost. So in this regard, should I change the capacitors to meet the low frequencies of bass guitars?

How about Dan Armstrong's Yellow Humper?

Yellow humper looks promising and i can easily had a 100K volume pot at the end i guess. I'll breadboard it and see if it's better than the mole.

Thanks again!

All the parts to the left of INPUT are the guitar or bass and cable part of the sim.  Remove all  the parts left of the input antipop resistors when you build.

You need the guitar/bass and cable sim with some effects to graph the frequency response because of the interaction of the guitar/bass cable and effect or amp.
This is the crap you read on the web about touch and feel and sensitivity to guitar/bass volume etc. 
It is science not magic.

Stupid me!  I guess it's the french thing. Now i get it.  I'll give it a throw assuredly.
Thanks, you learned me something today.

I use an just an EHX boost clone, works great and it annoys my guitar player to no end.

I had built an optical compressor and a sonic maximizer for a bass player a little while back. I have a bass rig here so I tuned the circuits a bit to work for bass. I gotta say the sonic maximizer helps boost the vol and dial in the tone with a bass when its set up right. I made a post a while back here with the values I changed to make it play nice with bass. Id suggest that since you can still keep your clean tone and maybe even shape your tone without adding any overdrive. Can use a separate pedal for any crunch you might want. the optical comp worked great as well keeping notes even and adding a little boost in volume as well.

I'm sure there are other rigs that are great but I really liked that set up. It was simple and it really made the bass sound solid and punchy. It seemed to help the bass stay separate in the mix a lot less mud, kept it clear.

The guy I built it for loves it and told me it gave him enough extra volume  and clear tone that he started taking a smaller amp to practice.

I too use both a compressor in the front and a sonic maximizer last. They are always on pedals for me. Once I added them, I wondered how I ever played without them.
