Preamps with High Pass Filters

Aaron · #1 02-01-2008, 08:47 PM

What is available for preamps with high pass filters? Preferably adjustable high pass filters.

Have we got a deal for you. Our very own fdeck makes one that is well thought of - and reasonably priced too.

gnergaard · #3 02-01-2008, 10:56 PM

I have one.
I use it on almost every gig.
best $50 I ever spent.

I've got the fdeck pre and it works brilliantly for my situation- EUB into a Nemesis 2x10. It doesn't have a huge amount of gain (+2 dBs, I believe?), but it really opens up the tone from the piezo pickup. With the phase switch, it's an excellent little tool for only $50.00!

BTW, your trio have any gigs coming up soon?

We've been on a hiatus, but we'll be getting some gigs booked now that the guitarist is back from traveling.

I've been really excited about some other things lately -

I've recently been playing with Bar Tabac. They have been my favorite group in the area, long before I started playing with them. I have a ton of respect for what they bring to music, and it is a real honor to be a part of it. We have a show coming up on the 15th of February at the Temple Bar that will be a special treat. The sound is a bit of a blend of wartime Parisian jazz and eastern European folk music, among a number of other things.

I was originally thinking something that had a single fully parametric eq plus a hpf, but that pre might be all I need. A fully or even semi parametric EQ is probably too much hassle for playing live.

i´m happy with the l.r.baggs gigpro i bought from François

I use this. I dig it in rooms where I need a little extra control.

Pro Platinum is a really nice box it costs $169.00, but it's got all the bells and whistles. Gig Pro has great features too at $95.00. FDeck's little box is only $55.00 shipped and has a 10 meg ohm input, Variable High Pass/ Lo Cut Filter, and a Phase Switch. Depends on your needs. Wouldn't it be nice if these controls were standard on all DB heads. AI and SWR and Phil Jones have done it. It doesn't seem to be rocket science.

I use the EA iamp200 (four-band, parametric tone-shaping) along with deck's marvelous little gem. I know that some find a parametric tone-shaping section overwhelming but, IMO, it is worth learning how to use one. For my part, both my job and my hobbies have resulted in my ability to identify frequency bands and spectral profiles pretty well by ear. I even have a technique to teach people to learn to do this so that they can better adjust their amps "on the job."

As for the HPF, you hardly need a gain control ("boost/cut") to adjust the action of the filter. Controlling its corner -frequency ("cutoff') is all that's needed and that's what fdeck's circuit provides.

To be sure, preference differ and if the L. R. Baggs works for you, then great! I had one for a day or so. For me, it would be a fine device had the company not chosen to "voice" the pre-amp by fiddling with the frequency response. The fdeck pre-amp/HPF is built to have a flat response throughout the passband (the frequencies you wish to "pass" or let through).

My main reason for wanting a fully parametric eq is to take out specific bands that are feed back. I generally don't have feedback problems, so I figure the less time I spend before a set twiddling with knobs finding out what specific band is feeding back the better.

hpf and phase switch should take care of any feedback issues.

That is my hope. I also wanted to scoop out some rumbling low end on my contra when I start bumping up the juice.

+1 on the fdeck HPF-Pre. Very effective and very good sounding and transparent for a bargain price.

Aaron,
That's what the Lo Cut/Hi Pass Filter of The HPF works on.

The feature that is really nice on the Fishman is it can be used as a direct box to the pa (xlr out) and there is a switch that'll either make that out pre or post eq. If you have to send a signal to the pa this is invaluable. So many clubs have idiots behind the soundboard that gives you some control from stage of your sound in the house system.

That's a very nice feature. I understand that it also has a optical compressor. Is that useful for DB?

Yeah. It's usually a busboy. Actually, it's usually the busboy's next door
neighbor. I've known some pretty intelligent busboys.

I sold my Contra before I picked up an HPF-Pre, but I always thought they might work well together.

[ I sold a GigPro to francois too.

I had the Series I Contra, and like you said the low end could get really massive in a way. I think it might have actually been partly due to piezo thunk and infrasonics, not just the fundamentals in the low register, at least in my case. But I betcha what you've outlined should tackle the rumble. Might work out real nice.
