General Questions / Planning my Harbinger One build
« on: May 06, 2013, 03:08:02 PM »
I have been reading about the power options, and have a question.

My board power supply has an 18v output which I don't use, so I can power it with 18v on my board.  But when I go over my friend's house to jam I don't always bring my board - sometimes I will throw a couple pedals & 9v power supplies in a backpack.

Has anyone considered setting it up to handle both 9v & 18v?  Maybe use a center-off toggle switch to kill power altogether and save the wear & tear on the bulb?

Thanks,
Bob

Build Reports / Finished my 1st 2 Madbean builds
« on: May 06, 2013, 02:57:47 PM »
I finished a Karate Shop / Harmonic Energizer:





And a Honey Dripper / Colosound Dipthonizer





I initially had some noise problems with the Karate Shop, but thanks to support from the forum that is resolved and it sounds great.  The Honey Dripper worked perfect first try, and it is an amazing effect!

Tech Help - Projects Page / Minor problem with Karate Shop
« on: April 05, 2013, 03:36:39 PM »
Hi - This is my first Madbean pedal, but I have ~ 20 successful builds.

My Karate Shop worked first time (great board & documentation, BTW!).  The problem is hiss.  The hiss is pretty loud, and gets worse as I turn the frequency knob clockwise.  I just verified all component values and orientation.  All stock values, with C1 using the recommended substitute of 2.2n.

Has anyone else had this issue?  Does anyone have any suggestions?

Thanks, Bob
