More bass in a Green Ringer?

[lerxst88]

soooo how could I do this?

[jefe]

The stock input cap is .047 uF, try different caps... that's where I would start.

The way that a frequency doubler works is to move everything up by an octave (or at least fake it real good).  Why would you expect it to be able to have more bass if you make the bass double in frequency?

Probably the only way to achieve what you want is to have a split signal from the first transistor and feed an unaltered treble-cut signal to be blended in with the final doubled output.  That's a little complicated for a Green Ringer and not really worth it IMHO.

well my brother uses it in his band and it has a great sound to it but cuts out the low end a bit. he plays bass too so low end is important

[John Lyons]

To put it in other words.

Here's a circuit that doubles the frequency (octave up) and in doing so cuts bass.
If you use it for bass you will be cutting bass as it doubles the frequency, pretty
straight forward...
You could use it with a blend circuit and get some bass back but you will
lose some of the effect of the octave doubling.
There is really no way around this...you either add an octave up and lose bass or
add back in bass, losing some of the octave up.

Try a Electro harmonix POG or HOG, that would solve the problem....$$$

You can try putting a resistor in parallel with one of the diodes - this will allow some of the non-rectified signal to pass through so you get a blend of the bass frequency and the octave up.  I think something in the 10-100k range would work as a starting point with higher values = more octave up.

No, I don't think that's going to work, simply because whatever one does to disturb the optimal balance between the two signals coing from the phase-splitter is going to ruin/degrade the octave effect.  I wish it were the case that one could retain the octave effect and simply push it to the background with some simple resistor changes, but that's not how it works, unfortunately.
As John says, if the OP wants both the octave effect and the bass content, really the only viable route is to get your bass content from the input, via a separate parallel path, and blend clean and processed together.

Wouldn't more bass in overall (by bumping up the input cap or possibly and active eq up front) result in a green ringer with 'more bass' content overall.  You're still splitting the frequency, but you've got a little more to go around, thusly a little more left over? 

[Mark Hammer]

How do you know there isn't enough right now?

[MikeH]

You just blew my mind...

Shouldn't upsetting the balance between the halves of the phase-split signal have approximately the same effect as blending in the clean signal?  For pure sine waves, the math works out so that blending some of the clean signal with the rectified signal should give you the same shape as attenuating one half of phase-split signal.  Is there something about the envelope or extra harmonic content of a guitar signal that causes problems that I'm missing?

Here's what playing bass thru the green ringer sounds like with a 47uF input cap...

That was one of the first pedals I ever built. There is a stratoblaster wired in before the GR and an orange squeezer wired in after it, so those are having some effect on the sound, too. Having a booster in front of the GR helps a lot, highly recommended. If I was going to build another GR for myself I would put a sho in front of it. If you compare the bass clip to the guitar clip, which was done with the input cap switched to a o.01uF, you can hear that the larger input cap definately takes away some, but not all of the octave effect. Single notes on the bass have very little octave effect at all, but playing double notes on the bass makes the octave effect stand out more. That's why I played both in the clip, so you can hear the difference.
