That entailed a slight redesign from previous units:&nbsp; there is no mixing of wet and dry signals here for instance.&nbsp; Also, the equalization was changed a bit to allow for the high pass filter to be applied to the input signal while the LPF was applied to reverb return.&nbsp; <\/p>\n\n\n\n<p>Yet the biggest change involved the reverb return circuit itself.&nbsp; Amplifying the small signals from a spring reverb can be very challenging with tubes.&nbsp; The springs themselves are very prone to picking up spurious noises and interference, and the signal itself is very small:&nbsp; similar to a dynamic microphone.&nbsp; Therefore, we challenged ourselves to find an even quieter solution which would provide ample gain as well as low noise.&nbsp; After studying some phono preamp designs, we hit on the perfect solution that is easy to install and sounds fantastic.&nbsp;&nbsp;<\/p>\n\n\n\n<p>&nbsp;&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Built for Tim Gane Yet another spring reverb unit, this one was built into an old DDR measuring device&#8211;
