Hi all, great forum! First off, please bare with me as this is my very first build (beyond simple ABY or relay boxes). Also, yay for me, this effect fired up on the first try! I love it when there isn't any trouble shooting.
Also, I have read every single thread I can find here about this filter, even the old ones from 2007 (which don't really apply, but I read em anyway). The 440 filter I assembled works fine (I think, see below), ie, led lights, sound goes through, effect 'effects' the signal... it acts like an envelope filter and all knobs respond to adjustment. I'm using a Warwick Thumb Bass 5 string into a Mesa M9/PH210.
So far, I've made only one modification to the effect: I switched the Manual pot from a A100K to a C100K
.... Hard to tell which I like better so far. Seemed to switch the sweep control from the last %50 of clockwise turn to the first %50 of clockwise turn.
Guess I shouldn't be surprised going from log to anti-log...My questions are:Is there anyway to broaden the range of the Manual knob
(beyond what I've done already)? ie, so that the entire range of rotation effects the signal.Does this filter ship with the 'bass mods'?
ie, the caps to use for a bass? There were no 'extra' caps in the kit. I did notice there were no .022 caps, so I'm guessing this kit has been updated for bass use. I just need a confirmation as this effect kills most of the frequencies below about 600Hz.I'm getting a high pitched squeal (high frequency) through the signal whenever I turn the knobs to their extreme positions. Is there a way to fix this?
Most notable is Attack turned all the way down and/or Sensitivity turned all the way up, and/or Manual turned all the way up (this occurred with the A100K Manual pot as well).Is there a way to improve the gain or response of the filter with distortion effects?
Or, like, at all? Though the low-end is mostly killed running bass > filter > amp, I find all but the highest frequencies remain when I run a distortion (such as fuzz) into the effect. This didn't happen nearly as much with the Boomstick Bottom Feeder I used to own, which is also a 440 clone. That is, am I possibly getting phase issues, or is it just the nature of this effect?
Most of the mods I've seen for this filter are for the first version, and thus the component locations are different, so changing R8 on the first version may or may not translate to R8 on this newest version. As such, please reference any modifications to this effect for the new board, version 1.1.
Thanks in advance. Any help you all have to offer to make this louder, more sensitive, more bass friendly and less squealy
is greatly appreciated by me (and others I'm sure).
