Hi Folks,

I'm gathering parts for the Pangea build & have found myself lost in 'Specification land' with the options for component choices.
Hope someone can help with some info. Sorry if this is a stupid question.
My choices for a 2N3904 Transistor differ only by DC Current Gain. Is this spec better to be higher or lower or does it really not matter at all in the context of a 9Volt stomp-box?
I have choice of 30, 100 or 300 hFe.
Just wondering

Thanks
Matt

Hi folks,
In case anyone wanted to add this simple mod to Sharkfin 2015- (Explanation views are from rear of 3PDT BYP Switch & rear of Linear pot)-
Requires disconnection of Bank C entirely from the BYP Switch & reconnection to a 500K Linear pot for Wet/Dry signal 'Blend'.

Disconnected BYP Switch C1 ('R' from PCB) & attached to the terminal 3 (left lug) of the 'Blend' pot.
Disconnected BYP Switch C3 ('I' link from BYP Switch B1) & attached to terminal 1 (right lug) of the 'Blend' pot.
Disconnected BYP Switch C2 (to 'O' on PCB) & attached to terminal 2 (Centre Lug) of the 'Blend' pot.

Values other than 500K will work for the pot.
Full anti-clockwise is 100% Dry signal. Full clockwise is 100% Effect signal.

When effect is not in Bypass, this 'Blend' pot allows the effect signal level to be balanced with the clean signal level & operates across the output jack.
Very handy when pedal is in Sample/Hold mode to add more playing flexibility & bring in a layer of drive among the all encompassing fields of bubbles.

When effect is in Bypass & effect signal is cut from output, 'Blend' pot controls the dry signal level only.

Only negative I've discovered so far is if you have the 'Blend' pot fully clockwise to 100% effect & then you kick into Bypass mode then your signal will be muted as the output is fully slanted by the 'blend' pot to 100% effect output only. I haven't had a good play on it yet but there was a noticeable drop in signal level from dry to effect outputs in the original circuit so this 'Blend' pot may also help to achieve balancing that out.


All Thanx to Charlie at Moosapotamus who came up with this mod a few years back for JD Sleep's FSH-1 version of the Maestro Filter Sample/Hold circuit at GGG.

Cheers  

  Hi folks. Very new here so sorry if this question has already been covered previously. Not sure how to find it at this early stage.
I just finished Sharkfin 2015. Great PCB from MadBean & great fun. Have no problems with it & worked fine straight off. No unwanted noises & very quiet in bypass too
I just need a little help with a mod & was wondering if anyone has put a Wet/Dry mix pot on their build of Sharkfin 2015 & where they connected to the circuit?
I'm not sure if I have to drop one of the switches from the 3PDT Bypass Switch to the output & replace it with a pot or whether it's a little more or less complex than that.
I'm guessing a Linear pot of about 500K would be ok but the Bypass Switch is freaking me out a little & I could do with a little guidance as to where & how I should wire the Linear pot in & also confirm a useful value for it.
Any help would be much appreciated.
Thanks
