Ah well' l thanks for your insightfull reply i guess its the old adage' there is nothing new under the sun....joking aside i didnt expect these ( New to the market preamps to be anything revelationary) for myself as my above script John East's brilliant preamps are still @ the highest standard for replacement & upgrading a Jazz Bass. Interestingly these T.F preamps are for j basses with 'Body Routed' output jacks only....as is the Sadowsky preamp also.... dissapointing that....?
