The Low Tide schematic was posted on a few previous threads: https://www.pedalpcb.com/docs/LowTide-Schematic-PedalPCB.pdfHAARP - Looking at the schematic, if the noise is only present when the WET control is turned up, I think it must be coming from the FV-1, 3v3 or Vref. Any thoughts?
Low Tide - The silkscreen in the build doco doesn't match the PCB I have. It makes checking component values and build errors very difficult.
Does anyone know where I might find the schematic or an image of the latest component overlay? Or where I could request this?
I've completed the ElectroVibe. It's STUNNING !!! It's the kind of pedal that will probably trigger a pedalboard re-build so I can fit it on.
Does your PCB layout match this build doc? There was an older build doc as well, but I can't seem to find it.
To hear the most intense modulation effect, set the Rate control relatively high and the Slew control to 0%. That will cause the delay to shift in pitch quite abruptly & randomly.
The amount of effect & it's response to your playing is somewhat limited by the internal trimpots. How did you set the BBD Bias & Gate trimpots? Here is the info:
- BBD/BIAS trim pot - Similar to the pot on a CE-2 or Caesar. Adjust for the least amount of distortion with modulation. Pretty obvious when set correctly. Set the Depth to 100% and turn up the output loud enough to clearly hear the signal. There is a range on the trimmer where you will hear the chorus/delay effect. At either end of the range, there is quite a bit of fizz. Just set the trimmer for the least noise.
- GATE trim pot - User preference, it controls the frequency of the low pass filter portion of the gate - Set MIX to 100% wet, LPG 0%, Depth 0%. Turn Gate Trim CW, you should hear the filter "open up" as you turn it up. You want to set the Gate Trim so the LPG knob goes from completely off at 0% to completely open at 100%, with a good amount of different settings in between - “I did have to fiddle with the external gate pot on mine to get a setting where I could hear the chorusing clearly, you may have to play around a little to get it completely tuned in”
- LPG ADJUST (i.e., GATE TRIM) - The recovery filter’s lowest frequency can be adjusted, to fine tune the way it will react to incoming signals. Lowering this frequency emphasizes the action of the low pass filter, effectively raising the threshold of sensitivity. Adjustment should be made with the following settings: MIX full wet, LPG minimum, DEPTH minimum. While listening to a signal going through the pedal, you’ll hear the effect of the recovery filter at its resting state. Carefully turn the trimpot labelled LPG adjust (i.e., GATE TRIM), clockwise to raise the filter’s frequency, counter-clockwise to lower. Be very careful, adjustments should be minimal as the trimpot is very sensitive. After each adjustment, LPG should be turned up momentarily to listen at the envelope’s response to the incoming signal.
