The String Ringer, from Elta Music, is a classic LT 44 transformer ring modulator. It is a modern replica of the Lovetone Ring Stinger. It has 1/4" connections for almost every parameter, making it essentially a module that can be interfaced with any 1/4" gear (or 3.5mm with converters). It has a built in modulator LFO, as well as a VCO to be used as either the Carrier or Modulator. There are three foot switches for LFO on, Bypass/Active, and Oct/ring. Made in Russia.
