One of my Twins' reverb tanks has gone bad; makes a dull ticking sound (okay, honestly, it's more of a farting sound) when jiggled, rather than the usual "boing." Nothing is visibly amiss inside, and I'm not going to spend the time to try and fix it since they are relatively cheap.
I always find the Fender Twin reverb a tad boingy for steel (I never play six string any more), and thought a three-spring reverb might smooth the sound out a little. I notice, however, that the impedances on the 9 spring pans don't match those on the two-spring spring pans used in the twin (10 vs 8 for input; 2575 vs. 2250 for output). Is this a no-go, or is there a little impedance flexibility here?
Also, does anyone have any experience with the MOD brand tanks? They claim to make transducers closer to vintage accutronics specs, among other things.
Thanks.

I'm using a 3 spring (9 series) tank in my "Twin" clone. The reverb starts about 1 1/2 and is too much by 3! Tried a "Mod", 2 spring (4 series) tanks, and a "Belton" 3 spring tank, but I couldn't tell the difference.
The slight difference in impedance is not a problem. |

Note that the "long-decay" tanks have a longer pre-delay, helping to separate the intial attack fromt eh reverb field a bit. I have both Type 9 and Type 4 long-decay tanks in verious amps and both sound fine, the Type 9 being a bit more dense (less choppy). Either way, I have recorded with them both and they both sound great. |

rip out the (unexciting in my opinion) LDR vibrato circuit and use the panel holes for dwell and tone controls - then you'll have the best reverb possible for steel guitar and I bet you don't use the tremolo much with steel anyway

Thanks for all the comments, guys.
Interesting idea Tim, I might just try that! I haven;t used the tremolo on a twin since 1978, and then just for one song.

Thanks, Tim, when I do open it up again, I have a switched pot to take the "vibrato" out of the circuit.
I haven't decided to add a "dwell" control yet though. |
