Anyone using an Fdeck with a Walter Woods head? I am curious how this would benefit me...

I use a Full Circle, WW Electroacoustic High Power into a 4ohm Acme Low B1...

Any suggestions? Should I use the Fdeck? Not sure what it would accomplish..just been reading how these help the sound and usability of the cabinet? Settings? Should I use it in the effect send/return loop of the Woods?

..new to this high-fi world...should have just kept the Polytone.

Thanks...

I've used the FDeck into my Walter Woods Ultra, with the Euphonic Audio VL 108 and 208. Woods amps already have a built in 1 Meg Ohm input impedance, while the FDeck which is set at 10 Meg Ohm. To my ears the difference between 1 and 10 Meg Ohm is enough to have me prefer the 1 Meg that the Woods already provides.

Acme and EA cabinets seem to require more amplifier power to achive higher volumes. It's my personal belief that's because they have exteneded low frequency response. The advantage of using the FDeck is that you can use it's variable HPF to take some of that low end out, but a little cut goes a long way. If you set the cut off frequency to high, you loose the character of the bass.

You can do it that way. Inserting the FDeck into the effects loop eliminates the 10 Meg Ohm input impedance, while retaining the High Pass, and Phase functions of the device.

Absolutely not, Walter Woods built superior bass amps, when his only competition was Polytone and Ampeg. There's no contest between them IMHO.

I have a WW Ultra, and an fdeck II. The low eq on the WW offers plenty of low cut control. I prefer the 1 meg input on the Woods as well.

Putting the fdeck in front of the Woods colors the tone, to my ears.

Where the fdeck really shines for me is going direct to FOH on ampless gigs. I use it often this way and really like it.

Agree, the Acme B-1 Cabinet has an extended low end, the HPF would be good to use if you need to a sharp slope eq cut off point on the low end. Many of the low freqs the the Acme cabinet brings out are the ones I prefer to taper off. It's really up to you; what you want to hear when you amplify your bass.

My Euphonic Audio VL 208 has that extended low end as well. Although it's pleasant to hear that on stage, I don't believe that it extends out into the house very far. It's also a drain on amplifier power to produce those lows. The EQ section of a Walter's amps goes a long way to taming that problem.
Those frequencies tend to get out of hand really fast.

Absolutely. I run my workhorse heavily modded Englehardt with a realist into series 2 F-Deck and WW into an Accugroove Tri-112L.

I prefer the series 2, and I like what the filter does when I need low cut. I can surgically remove low end problems and barely need any EQ on the amp. One of the best $70 I've spent. The phase switch is useful at high volumes too.

Thanks for all the replies on this...

I did find the Acme to produce some heavy sub frequencies...agreed that those are not necessarily ideal for my purposes...but the cabinet itself sounds pretty killer..better than anything that I have owned in the past.

I will try the HPF and see what happens, not a huge expense.

I am also getting a Big E 45 built...looking forward to using this cabinet as well...this may replace the Acme...won't know until I hear it though...

I received my MAS45 about a month ago and I really want to compare it with a B1 or one of the new 112s. It's been a few years since I sold my B2 (mistake, I was playing in a Top 40 and wanted a more traditional sounding rig for EB). I didn't like how the realist sounded through the B2 but now that I'm on the EAP I want to try again. I think that would sound killer.

How many of you are still using your Acme with DB and what piezo/mic are you using?

I did a comparison between my Audiokinesis TC 112 and The Acme Full Range. It sounded really good but not as defined as the Thunderchild. The older Acme B1 and B2's had very good low frequency response, but the trade off was the power from the amp that it required to do that. I always
felt that it was pleasing to have the lows on stage to listen to, but they didn't travel very far out into the audience.

Ric.

I experimented using the FDeck Series 2 & Series 3 through the effects loop of my Walter Woods Ultra and wasn't happy with the sound. IHMO they sound better into the front end of that amplifier. It can definitely help you roll of that extended low end of the B1 in a room where
it was an issue.
