[sdiy] slightly OT: best tube tremolo? table radio amps revisited

[dave at westphila.net]

The tremelo/vibrato found in the brown fenders sounds really good.  It
splits the signal into high and low frequency bands and modulates them 180
degrees out of phase.  Uses 3 12AX7 tubes to do it but it's much more
interesting to my ear than the plain bias vary tremolo.
