Hey all, I've got a simple question regarding a rather unusual guitar setup. It's for a noise-punk band I play in, where the goal is to have the guitar be as harsh and treble-y as possible, like if you can stand in the same room as the guitar without earplugs, something is wrong.
Current setup is guitar through three distortion pedals into an A/B/Y box, with one output going to a 6505+ half-stack and the other going into a Peavey Mark VI bass head with no speakers connected, then from the high-frequency output of that (HPF set around 1.5kHz) to a small PA head, which feeds 2 speaker cabs, each consisting of 6 piezo tweeters. It'll make your ears bleed.
Anyway, we used to blow tweeters all the time feeding them a full-range signal (luckily replacements are only $2 apiece), so the Mark VI is being used for high-pass filtering, because it's the only high-pass filter we have access to currently. It's been working out great, but obviously it seems like a waste to drag a whole extra amp to gigs just to use as a high-pass filter.
I'm looking for a simple, cheap alternative but am not sure how to go about it. I'm imagining just making a simple R/C circuit in a RadioShack project box, but I feel like it might require something more complex than that. Decreased signal level is not really an issue; the tweeters' amp is set with the volume less than "1" now and it's unbearably loud. Noise imparted to the filtered signal is not really an issue either; at this point the guitar is close to white noise anyway. Something passive would be preferred but not really necessary.
Suggestions and advice would be very much appreciated, thanks in advance!
