I just completed the build of a Quaverato. It seems to be working properly. I have however noticed a dramatic difference when the Quaverato has a buffer (or engaged pedal) before it, as compared to guitar straight into Quaverato.
The buffer or engaged pedal into the Quaverato results in a significantly brighter tone and more volume than without.
When the Quaverato is engaged without a buffer, it significantly darkens the tone, compared to the bypass signal.
It is not really a problem, and I have experienced the same type of effect in other LFO modulation pedals.
But I want to know if this normal for the Quaverato, or is there an issue here.
Thank for the post Mark.
Yes, what you’ve discovered is expected for the Quaverato. This happens because the high frequency signals have much less impedance going through the pedal input and U2A (the first opamp stage) than the low frequencies. You should be able to adjust the HPF and LFP trim pots (while testing it inline with a buffer pedal) to make it sound more natural. If you want to go deeper, a mod you can do to reduce this effect a buffer has on the brightness of the pedal is to add a capacitor in parallel to R3, which will allow the high frequencies to pass around U2A without being amplified/buffered.
That may be more information that you wanted to hear, but hopefully that answers your question.
Thanks for the reply. I am glad to know it is working as expected. I always have some buffered pedal upstream, and I prefer the brighter sound.
The pedal sounds great. I especially enjoy the harmonic mix feature.
The assembly instructions and board layout are excellent. And the build experience was very enjoyable.
