Bias adjustment

Post by D Mocker » Fri Sep 18, 2009 6:20 pm

I just bought a used Drag'n'Fly off the forum. It's my first D*A*M pedal and it sounds great, but I wonder if I need to adjust the bias. On the D*A*M website it says "unity at full bore is the norm". On my pedal unity volume is around noon and it picks up radio stations even at lower levels. Do I just turn the little white dial counter clockwise?

Thanks,
Damon Mocker

Probably best to leave it especially if it sounds good. I find that a fuzz's output has a lot to do with the amp being used.

:hihi:

The newer Fly's do have a tad more volume than the older models but the overall output volume will appear to vary with different geetars and amps. The trimmer adjustment, I imagine, will not cease any radio interference. That will be down to your location.

Altering the trimmer in the Fly will do no harm so if you wanna double check for yourself just be sure to make a note or mark the current setting of the trimmer pot. Best advice I can give in messing with trimmer pots...use the correct size of screw driver. :tu:

Thanks for the replies. I'll just leave it alone. I played it some more today and I certainly have no compaints about the tone. :headbanger: Even the radio signals add some cool weirdness. :cool:

I just want to post an update on this issue. I replaced my old cables with Lava cables. All noise issues have been cured and the Fly is sounding better than ever.

After reading this thread I spent some time twiddling the bias of my Drag'n'Fly and it did a world of good.

The setting it came with would splutter out a bit after a while like a little two-stroke engine running out of gas. I messed around a while to get the smoothest setting that still had enough hair and the performance of the pedal was dramatically improved. I suggest the first thing anyone should do when they receive this pedal is set the bias to your liking.

What worked best for me was maxing the 'Attack' and 'Filter' knobs and putting the 'Level' knob at unity, then I held a note and adjusted the small pot inside until the note wasn't spluttering and juddering randomly. Then I did minor adjustments to the bias until the pedal was as fat sounding as possible without the sound randomly cutting out. Though if you are looking for a spluttering sound you can do the opposite.
