Looking for short reverb. 32 ohm input, 220 ohm out. The reverb time decay can't be right. Milliseconds not seconds. They are not echo chambers.
Asked by Anonymous on August 5th, 2017.
The length of time required for the arrival of the very first reflections is called the delay time (usually on the order of tens of milliseconds, e.g. 33 ms) and is related to the volume of the room (or distance of the reflective surfaces from the listener). The number and density of reflections increases rapidly with time and they become cluttered while simultaneously decreasing in level until they are no longer audible. The length of time required for a sound to decrease in level by 60 dB is called the decay time (usually on the order of a few seconds, e.g. 3 s) and is related to the acoustical properties of the reflective surfaces in the listening area. For example, poured concrete walls will reflect more (absorb less) acoustic energy than drywall.
This tank has a medium decay and can range from 1.75 to 3 seconds. Unfortunately we do not carry a tank with a 32 ohm input impedance and 220 ohm output impedance.

I have a ROLAND JC-77. The original reverb tank is 2 spring unit. But some people replace it with 8AB2D1A . Which do you recommend 1AB2B1B or 8AB2D1A ?

We always advise replacing reverb tanks with the exact replacements originally installed in your amplifier. The most important considerations to be made when changing the tank is the input/output impedance as well as the connectors. You will need to verify which (input or output) connection is grounded. All other factors can be altered without damaging the amp.

I'm looking for a reverb tank for a Crate Vintage Club 20 amplifier. The original tank was a Belton two-spring short-tank--the only designation that I can see on the tank is a small sticker that reads "70-222-01". Is there any tank, exact or close to it, that will work for this amp? Thanks!

We do not have sufficient cross reference materials to verify what tank was originally used in that amp. We suggest bringing the amp to a local tech to determine the input and output impedances that amp requires and that will significantly narrow down your available options.
