Does anyone know what kind, model no., etc of reverb tank I could use as a direct replacement for my Webb? The old one starts sproinging if somebody in the club sneezes.

What model is the spring unit? The numbers should be on the top of the can.

I don't have access to it now, but it's the one that came with it in '78.

I just spoke with Jimmie Webb last week about reverb tanks. He said that the original tank # was : 4FB 2A1B

BUT, I dont know if that's for that '70s vintage or if it's original for the '80s/'90s models or what. I think there were 3 different tanks in the 614-E history. The first was a 2-spring, then a 3-spring for a long time, and now I'm not sure what the stock one is. So somewhere in there the original was this model #. Mine is a '77 or '78 614-E and it has a grey metal 2-spring tank. Maybe a Hammond and not an Accutronics, I cant find a number on it. Track down Danny Hullihen, he seems to know a lot about the Webb reverb tank situation. Danny did say to me that the different tanks used by Webb all sounded pretty much the same in that amp, but he tends to prefer the 3-springer. But then there's the issue of a short can or long can as well. Confused? I am now that I think about it.


By the way, to add confusion, often times a 2 spring tank is listed as a 4 spring, and a 3 spring is called a 6 spring. This is because for each spring, it's actually two springs connected end to end. The key issue for any reverb tank is it's input and output impedances which must be right for it to sound right.

Brad: as per your other Webb thread, my S/N is 969, so it's got to be pretty much the same as yours, (960). So...is there a direct replacement, or maybe something I can do to fix it?

Ok, here's more mind junk for ya'll.

*********************************************

Accutronics Reverb Tank #4FB 2A1B =

4 - 17" long can with 2 springs (4 really)
F - Input impedance of 1475 ohms
B - Output impedance of 2250 ohms
2 - Medium decay 1.75 - 3 seconds
A - Both input and output are grounded
1 - Has no "lock"
B - Mounting plane horizontal - open side down

Tanks that start with 8 are the short 3-spring types.

Tanks that start with 9 are the long 3-spring types.

***************************************************


Michael, I'd replace it. The springs can get both sloppy and feedbacky when they age. I think you should just replace it with the one mentioned above. That seems to be what we've got in our old Webbs. I'm real happy with the sound. Check out Antique Electronic Supply or Mojotone.com for decent prices on these tanks. Shouldn't cost more than $25.

Ok, did a little research. You wont find this tank thru any dealers that I can find. You gotta go straight to accutronics.
http://www.accutronicsreverb.com/

Call them and order it. It's $23.70 and will take about 2 weeks to get. Give them the number 4FB2A1B.

Good Luck,

Thanks Brad. That sounds like the ticket. You can close this one.
