This is a very nice RJT 60 Jazz Master. Entwistle X 90 Ceramic P/ups A T N circuitry disabled, selecter is in situ and the rest is stowed neatly behind the Pick Guard if you should want to Re- Introduce it. As far as I know it was by-passed for the previous owner to avoid confusion as So many configurations may have been mind blowing. As it satands, these pups are meaty and sstill very much variable Thick or Thin. Come try it, but price is not very negotiable. As it a outstanding guitar and not a gamble
