Re: BM/HRM soundcheck

What's with the trimmers on the PS board? If they're dropping string adjusters are they in series, or parallel? Yeah a friend of mine, named Paul Klatser, came up with the idea.

Re: What causes the "bloom"?

In my case; the moment I added the PI trimmer to my DLite things got way better... More bloom, more harmonics... grtz Lars What value do you use on that pot? And do you have identical values on the plate resistors? In what position do you think the pot gives the most bloom? Tommy I have 100K and 11...
