Has anyone who's built this with the Tonepad board had a problem with (seemingly) the noise transistor (best results in terms of the filter itself were with 2sc1815 and 2n5089 for me) adding a lovely high pitched whine to the signal? Pedal works beautifully other than that (and there's even some nice sequencer-y effects from the whine and the S+H! :lol:)

Did this one with all the mods - not convinced how useful they are ultimately as I only really want the S+H side so am quite tempted to knock up another enclosure and go for a more original vibe!
