Title: Fix vs low/high pass filter
Post by: Cleet Torres on July 05, 2014, 04:59:50 PM: Apologies if this is a bit (or a lot) of stupidity on my side.

Can a Fix be tweaked to act as a high pass filter? I am looking for a high pass filter, and given my other Bottlehead gear, The Fix would be a nice match on my rack.

Thanks guys.

Cleet.

Would you still be agreeable to sharing this? I'm getting Orca mini's for tweeters for my horns and want to modify a Fix (since I have one) to house a switchable filter.

PM me an email address and I'll send it.

The old thing is pretty grody after all these years, and most of the switch labels are worn off now - they were written with a sharpie originally. I think the switches and pots all came from Radio Shack. We did a lot of interesting experiments with it though.
