Too much headroom on Hwy 89

[Traintrack]

A good album title!

Built this one and @ 8 o'clock on the volume it is dog barking time. Can there be value to swap to pull this output back a bit?

Thanks

More voltage=more headroom, less voltage less headroom. Though I don't know how much voltage you could lower. Maybe you could try with the "dying battery simulator" theres info on that at GEO

Bye bye

hope it helps

if you mean the overall output, you could try a smaller value vol pot, say 250k, or 100k.  if you mean gain/dist, it's built to be a high gain rocker so something must be wrong w/ yours.

I have tried a 100K Pot and it still can blow up an amp!

Funny about the low voltage, I tried a dying 9v and it still is over the top. The gain and tone all adjust fine.

It's the Volume knob that spikes at 8-9 o'clock.

I figure that there must be something up with my values in the build, but i built two of them and they are both lethal.

Any suggestions?

try an audio taper pot. The pot 'action' won't be all bunched up in the lower region.

Thanks ED,

I was also wondering about increasing the R-16 or the C-12+13.

Thoughts?
